Even having both types, they still are available/receptive on different days... So it's not as solid as most promote it. I think wind and insects/bees are the best pollinators for avocados. That said, I think 1 tree of either type should provide good fruit production. I think investing in attracting bees into the yard is best. My 2 cents.
Hello! I must say I'm a fan of your videos and find them always useful and easy to understand! About avocados my curiosity was especially intense, since I started many (more than 20) years ago with a seed planted in a pot and eventually transfered the seedling to a spot in the ground. I live near Lisbon Portugal and climate is close to S. Francisco California. Now, At the time I didn't have a clue that I was risking total failure and the tree took some 15 years to mature and flower the first time. (true...I kept it too long in pot culture so those first years were wasted). When it flowered the first time I had already collected much info about avocado culture and characteristics including its special flowering habits and was not expecting to get any fruit. But to my surprise that first year I had about 30 fruits and even to greater surprise they were of good size, easy to peel and quite dense and oily creamy nut flavored. So I must have been very lucky in my first and only attempt. Now I know that the flowers are type A becaise they are synchronous with a grafetd Hass tree I bought in a gardening center, and also they are assynchronous towards two bacon trees I also purchased. My main point here however is about a detail I noticed in the flowering of these 3 varieties I have planted . The first to set flowers always is Bacon, and for some 2 weeks or more that's all there is. Only later do the Hass and my "new variety" trees come to flower, and the period when you could find the 3 varieties flowering together is short. So my question is: Would it not bem more important to know the flowering periods than the A or B types when planning a plantation? To be honest I noticed that even before I got B varieties to complement my A variety trees they flowered profusely and were litterally covered in small fruits that they eventually shed , keeping only a small percentage to take to full maturity. I believe that the trees would not survive if all fruits were kept and fed to the end. So why do people only consider the flower types and never take into account other factors? Thank you Jorge
Thank you MH MH! I waited all year for this educational opportunity to share with you, and other's interested in the details of avocado pollination. Thank's for taking the time to write me! :-) Charles
I am currently planning and designing a 44,000-Tree "Class A Hass" Avocado Orchard on 250 Acres. I need to know the ratio of Class B Fuerte trees to mix with the "Class A HASS" to give me effective cross-pollination and bountiful harvests. Any information would be much appreciated.
We just published a lesson with orchard avocado tree expert Carlos de la Torre with links to his RUclips Channel so you can get the most accurate answer. Also, he explains in the following lesson that not all Type-B avocados are effective at accomplishing significant cross-pollination. Check out this recently published lesson: ruclips.net/video/H3oC26-Khgc/видео.html
The evolutionary benefit might be avoiding self-pollination and maintaining genetic variation by cross pollination. Genetic variation is in theory an adaptive advantage, giving more flexibility to adapt to new environmental challenge...But it still remains a huge question: why self-pollination doesn't bother some plants at all, they thrive and are perfectly fine with it since eons, while other species want to avoid it?
Because some are just genetically perfect and they still didn't faced a challenge to exist, so they still didn't developed the complex system of cross pollination
Great video. I just got the impression the orange flower is behaving like a couple that get along really well ...while the avocado is like a couple where one is complaining of headache or the other is pretending to be busy or asleep. Just me being a little extrovert. I love your works.
Thank you I've been asking avocado tubers if air layer was possible I saw you fig air layering it was inspiration the smaller pots in larger pot I still use
Now I got it when people say that you need two avocado trees, doesn’t mean that you are going to have a female and a male one but it’s means that you are going to guarantee the pollination according the time when the flower become male o females and can be pollinated I was confused because I also read that avocado trees are self-pollination but this depends on the variety.
Those suckers are usually good to remove on other types of trees, but those suckers on the avocadotrees form the skirt on an avocado tree, which really helps with temp regulation, moisture retention and other benifits. Also note as others have said, a and b trees need consideration to when they flower.
I cut my indoor avocado tree from the top and it now looks like it's turning and dying from the top. It is a grafted Hass avocado tree. it was bare and dying and then I put some citrus tone in the soil now it growing but I don't want the brown to travel the stem and to new growth branches. I don't think the tree is rot from the bottom. What should I do? Should I order IV Organic paint and cut the tree from the top and paint it with the IV Organic?🤔
I found it interesting that you used a Q-tip. I've read that people who have problems with pollinators just do it themselves with Q-tips. Some also say that honey bees are sometimes not enticed enough by the flowers so they spray a sweet solution on them. Well, from the looks of this video they seem to love your flowers!
Hello Jerry, Thank you! :-) And with regards to spraying the flowers, I would recommend planting native flowers which will attract the native pollinators in the area that will visit the wild-flowers and pollinate the avocado on the way... check out some of our videos discussing native plants by searching: "IV Organic Native Plant". I also interviewed Lisa Novick who is the plant expert on natives in the Los Angeles area. Check those interviews out to learn how planting the right stuff can improve the success of your fruits and vegetables in your garden! Charles :-)
Great demonstration! I'd guess the incompatibility evolved as a way to prevent inbreeding, which would have weakened the species. Having A/B types makes it more likely for a plant to be pollinated by a more distant relative, even if lots of close relatives were growing nearby.
Hello Tohopes, I LOVE that explanation! The cross-pollination between related species of avocados would further increase the diversification of the seedlings to better handle changes in the environment and increase the perpetuation of it's species compared to the other 99+% of angiosperm related flowers that encourage fertilization between the sex parts in each of its individual flowers-- on the same plant. GREAT EXPLANATION!!! Charles :-)
My great grandpa had acres of avocado in Mexico and said the key to production was to "make the wood bleed." He would take a crowbar or bat and whack the trunk of a mature tree a good 2-3 times until sap came out (just enough to crunch through the bark). My dad had a single avocado tree in his yard that gave a couple sad avocados a year, and finally tried out the crowbar method. Suddenly that single avocado tree gave so much fruit he was sick of it. I'm wondering now if the trauma to the trunk of the tree somehow forced it to... disregard its type A/B cycle so its pistil and pollen are available at the same time. Any thoughts?
I did the same to my poorly fruiting avocado tree...went out early so neighbors didnt observe me whacking my poor tree with my kids baseball bat and low and behold...avocados! This trick definately works.
My guess,whacking the tree dislodges the pollen from the male and falls onto the female part of flower hence pollinating the flowers. I see how that could work.
I believe the reason the avocado has evolved with its flowering as it does is to limit the amount of fruit on the tree. One tree produces way too many flowers and I've had a Hass tree one year have almost all the flowers fertilize and there were a million little baby avocados on a tree that the tree could no way support and most of them dropped off. It's very unusual for that to happen but it's probably evolved so that it does not produce too much fruit.
Great Video. Question. I live in Florida. I have a 5 ' tall Haas Avocado that is planted in full sunlight. To protect the plant from the extreme sunlight and sunburn, I want to use the IV Organic featured in your video. But we have a rainy season in Florida. Will the constant raining just wash the IV Organic off the avocado tree? I'm wondering how resistant the dried IV Organic will be to our daily rains. Thank You.
Not always true my friend about the length of time a tree requires to grow from a pit before it produces avocados on it's own. I have a well documented avocado tree here on RUclips which I grew from a pit that bloomed first when it was 4 years old & produced about 50 delicious full size fruit when it was 5 years old. The next year when it was 6 years old it produced 330 fruit - the largest of which was nearly one pound & about 7" long. Last year not so good, but this year, at almost 8 years old, it has millions of blossoms starting to hold their fruit. We've already had guacamole for years from our 7 year - 10 month old tree. It will be 8 years old this may & all I do is water the heck out of it. And by the way, since I water the daylights out of my trees I've never had to paint the branches to avoid sunburn either.
Hello Duster Dan, You are correct, there are exceptions. It looks like your avocado trees performed 2x faster under your growing conditions and care! :-) I just checked out your avocado trees that you published--- LOOKING GREAT! Thank you for sharing your avocado growing successes!!! Charles :-)
I planted an avocado seed myself ,I think 6 years ago it just start flowering,I was a bit worried base on all these information about the avocado plant needing more than one plant in order to pollinate. Thank you very much ,your explanation now gives me new hope.
Hi there, I have a very old Reed avocado on my property and would like to know, what is the best fertilizer and best way to care for it. it is over 40ft tall above the house. and can't get the fruit. when is the best time to also prune it, and will giving it a heavy prune. Like top off. effect the tree for the next season? as being so high I have trouble with the birds getting the fruit before it is ripe. thank you
Even though it's best to keep larger-maturing trees small than to reduce them, reductions to managable size can be accomplished over time. A skillful reduction of the tallest branches will let light into the center of the tree without opening it up so much that the bark will be sunburned. That light should encourage interior sprouting. You select and nurture those interior sprouts, and make sure that light continues to enter and keep them alive and growing. Continue to reduce the upper canopy in carefully-planned phases, all the while keeping the bark shaded, and only pruning off 20% or less of the total foliage annually. You could probably achieve the reduction you want in 5 to 7 years.
Thank you for a detailed explanation of polination process, still have one question about it- how do I manage a successful polination process in a greenhouse with no insects, by hand? How do i know which flowers to collect pollen from in the morning and in the afternoon? Tried to make flies do it but it didn't work - they are lazy and not doing the job, and don't have bees in blooming period in my area🤷
My 3-year-old, potted avocado tree appears healthy, but has become very "leggy." Many of the branches are over 3 feet long, but they are bare starting from the trunk, and then lots of leaves near the ends of the branches. They are hanging low. I'm told that trees should not be allowed to bow down or even go horizontal. Should i prune these branches back?
I wonder how long pollen is viable. For instance if a bee or some other pollinators have some remaining pollen on their body from the day before, would it be possible that this pollen is still viable and can fertilize the ovary?
I planted two seeds from store bought avocados and they have take off but no fruit yet. I do have one I bought from nursery about three years ago but no avocados but it does flower but last summer took a beating from heat in Northen CA. Should I graft my seed growing avocados since they are big trees now and if yeast when should I graft it?
So, I understand about open pollinated/heirloom plants and how they become a hybrid if they cross-pollinate. If I have just one Haas avocado tree, the seed would stay true correct? I could plant the seeds and they would 'come true' to the one parent plant. What an interesting plant! All assuming there are no other types of trees around. Is that what I understood you to say at around 19 minutes?
Hello ,Please tell me i have young tree and it flowers turn into black balls what is that when u pick it your fingers turn purple .what is male and female tree.
What if you tie a bag around the bunch of avocado flowers? Would the pollen from the previous night/day pollinate the female flowers during the day/night?
Such great information. Thank you. The Cherimoya is somewhat similar but a bit more complicated to pollinate since none of the chirimoyas natural pollinators are in California. From what I understand the Cherimoya flowers are female in the morning and then become male at night. Since natural pollinators aren't here in CA, most people hand pollinate the Cherimoya collecting the pollen at night and then using a brush early in the morning to brush the pollen into a female flower before it dries up. The Cherimoya tree is actually fascinating. And the fruit is delicious and SUPER expensive (usually about $9 per pound). I have two baby Cherimoya tree in my back yard that I'm growing from seed. I actually just recently used your IVOrganics on ir to protect it and the trees are going great! Would be awesome if you did a video about the Cherimoya tree.
Hello Sergio Rios, I love chirimoyas!!! And it has been my goal to grow the things that are (1) most expensive to purchase (so that I am getting the best return on investment in my garden), (2) most delicious eaten the same day (such as figs), (3) and just to make the most healthiest, freshest, most nutrient rich and organic foods to share with my family, friends and neighbors-- the foods you cannot buy anywhere else! I will be on the lookout for an area to squeeze one of these trees into my landscape. Great suggestion & thank you for that awesome testimonial! :-) Charles
Hello Mr Charles! Your info on avocados rock! Also thank you very much for name Chirimoya, which it's it correct name, no cherimoya! I wish the same would go for the Guayabas, instead of guavas! Do you have any plans for investors? I'm wanting to invest in your product Drop me a line Silvia M.
@@2013december, Yes, I now have 3 . I had a tree that was at least 65 yrs.old that was in terrible shape, so last year I stumped it , and this year it's producing two beautiful offshoots . God is good .
I have my 2 in semi sun. They don't get full sun. Here the temp. go up to 1005 in the summer. I'm trying to grow a second avocado in a container. It's growing beautifully but don't know if it will give me fruits.Great video.
Mine is a type B. It flowers like crazy but none of them turn into fruits. Is there anyway I could get the pollen transferred from the male ones (in the am) to the female flowers (in the pm) and speed the process?
Hello Stela, Thank you for the compliment! :-) Ask my friend Carlos, in Miami. Here is his RUclips Channel: ruclips.net/video/wg9T7rh2ed0/видео.html When you write to him, let him know that you were referred by Charles at IV Organic. Keep me posted! :-) Charles
I am also looking for some but I live in Australia. If anyone in Australia can help me out I would love to buy some hass and other varieties too. I have bacon and fuerte I got from nursery but I want to graft onto my seedling trees I have at home.
So, When the plant dies, seeing how full your trullis is, Is there a time your yard is left naked every 3 to 10 years? I realize you plant new starts, but how do you cycle them in? Several base vines? I am in Utah zone 7. Hopefully I can get a system that works here.
I have a avocado tree, I'm not sure what type A or B. My avacodo tree has lots of flowers, bearing only 1 fruit in last 7 yrs. I would like to plant 1 more avocado tree, but don't know my current tree A or B? Please help. Thanks
Where is the bro have 9 avocado trees that I planted from seed. They are 1 year old this month and theyre about 1 ft to 1& 1/2 ft tall. A couple of them aren’t doing so well. I’ve been considering grafting a couple of them to see if that would revive them. Any idea where I could get some scions? And any advise would be greatly appreciated. Also I live in north Texas so we’re not so lucky with clay soil.
I have a avocado tree that is like 2 or 3 year old from seed that was given to me. its been in the ground for over a year now. Its now starting to grow pretty rapidly.(looks amazing) but I was wondering. because its from seed should I graft other varitys onto it? or just let it do its thing? I herd if you do from seed there is only a 20 percent chance of it producing fruit. Any advice???
I have a question. I have a 12ft hass avocado tree it has two main stems right up aginst eachother coming from the ground. Should I cut one? they are both healthy and thick stems about the same height.
My pinkleton is dying g up in Sacramento. Don't know what to do. Bought at Lowe and it's only been a month since I put down soiled. But my Fuerte and Beacon Hass are doing fantastically except for Pinkleton.
sweettravellumkan Lowes has a 1 year free replacement as long if you have your receipt. If you lost your receipt they can look it up by your debit /credit card.
How do o know if my avocado is a or b , mine is a hass from planted from a seed bought at a store. Is an 8 feet tall now. It grow small in the yr.2013, then it froze that yr., then 3 more branches came out out that 1 tree. It's now 2020 and still alive but never have bloom. What type I need so this one cannbloom?
Can I buy a type B fuerte from the store and cut it off above the graft and then graft it to my hass? Or do I need to wait for the store bought fuerte to fruit first?
Hello,good video for farmer who plant fruite plant, what do u mean by B type? A type,you mean does not need male and female plant at same time to plant?
I am going to say that I planted my Avocado from a pit, about 10+ yrs ago. I have no idea what type it is. It has never had flowers On it. but we did find a small fruit on the ground one year, it had fallen off the tree. I've never found another one since. By the way we live in the deep South and it is hot here. My tree gets direct sun all day and I've never found any sunburn on my tree. It was a very big tree and one winter it got below freezing and died off, but started growing again in the spring. Is there a way I can tell what type of tree I have.
Great video thanks for sharing all your knowledge! I live in Perth Australia and we have a type B „Wurtz“ Avocado for several years without any fruit so far. Since we are now in spring (September) I have some flowers on our Wurtz and hope for some fruit. After your A and B explanation I believe we would get more success by also having a type „B“ but we don’t have a lot more space in the garden and so I wonder if I can graft a type B scion onto a branch of my existing Avocado type A. Do you think this could work? And what would be the best time to do this spring, summer ...? I would also be interested where and if I could buy your Sunscreen protection products in Australia if you’re selling them here. Thanks for any information and happy gardening!
That depends upon the ultimate size of the variety that you plant. The new 'GEM' variety is adapted to dense planting, but 'Fuerte' grows to be a large tree.
I grew saplings from seed in 2002. All were of same variety - Fuerte. After 8 years all three trees bore flowers & fruits.Apparently the trees were self pollinating. This season, in Mar 2019, I found that another plant grown from seed of my mature trees is bearing flowers for the first time - in 6 years. I found that an unsuccessful graft on its trunk had girdled the trunk at three places. I failed to remove the plastic wrapper! Also I had chopped off the upper part of the tree to keep it within 8 feet height. Could these action, by default, be the cause of early fruiting?
An evolutionary reason for the 'A' 'B' pollination schedule could be that the fruit is very heavy. Too many successful pollinations could result in the branches breaking due to many fruits hanging from it, thereby defeating propagation
My avocado tree produced a bunch of fruit last year but none this year while my smaller avocado tree is producing, not sure what is going on but any information would be appreciated. Love the videos!
Hi, i live in Huntington Beach, CA, zone 10. I would like to grow asparagus and brussel sprouts, but both of them are not recommended in my zone per one seeds website. Would you mind to provide your thoughts ? Thanks
I had an avocado tree was grow from seed for three years old. no flower .can you please tell me why my tree is not flowering? thank you in advance. I am staying in tropical climate.
Hello Peter, Yes. All avocados are self-pollinating. One tree is all you need for success!!! :-) Keep me posted on your avocado growing successes! Charles
You're welcome Peter! I love hearing the positive experiences people are having from these videos... And I too learn SO MUCH from your feedback too!!! So thank YOU for the comments! :-) Charles
Hello Tortaboy, Yes. Adults feed on nectar... and in the process pollinate the flower. Wasps are also predators in your garden eating gnats, caterpillars and flies.... just to name a few. Check out this video I did not wasps last year: ruclips.net/video/MWmRiTjuPq4/видео.html Let me know if you have any other questions! :-) Charles
jill Lavinger Look for the tutorial that is called “Anillado en los árboles de aguacate”, I think you can watch it with subtitles in English. This tutorial shows a process of cutting a ring all around the tree that forces the tree to flowering and really works because I did it in my two avocado trees and worked!!
Thank you for a clear explanation of "A" and "B" avocados ... I got it! In the Central San Joaquin Valley, would it make sense to cultivate perennials that bloom and attract pollinators the same time that avocado trees bloom and what might those perennials be? Thank you , Stella from Fresno, CA
It seems like those avocados are planted fairly close to other trees. thought avocados needed a lot of space. Is planting a non dwarf variety 7-8ft adjacent to other trees considered ok? I'm wondering because I have about that much space left in my backyard :)
I feel like it's possible that avocado trees vary from one to the other in how their flowering happens. The way youre describing it, it sounds like the male and female parts of the flower are open and exposed at the same exact time on the very same flower. And that may apply to certain avocado trees. I'm not sure. But my understanding is that an individual flower will open and close a few times before it dies and that it alternates it's sex each time it opens. Meaning that the same flower will act as male during one showing and then act as a female the next and alternating back and forth until it finally dies. I will send you a link demonstrating the subtle difference between an avocado flower positioning itself as a female and then later positioning itself as a male. The flowers are so small that it's very possible one could miss this very subtle difference.
But after a certain time in blooming both type of blooms are open at the same time I have cica killer wasps approximately 2 in long on the avocado flowers they are nectar and pollen water I also spray my flowers with raw honey and distilled water brings everything
My Reed avocado self pollinates, it flowers twice a year so yield is awesome
The best explaintion I have ever heard, thanks.
Even having both types, they still are available/receptive on different days... So it's not as solid as most promote it. I think wind and insects/bees are the best pollinators for avocados. That said, I think 1 tree of either type should provide good fruit production. I think investing in attracting bees into the yard is best. My 2 cents.

It will be 8 years old this may & all I do is water the heck out of it. And by the way, since I water the daylights out of my trees I've never had to paint the branches to avoid sunburn either.
Hello Duster Dan,
You are correct, there are exceptions. It looks like your avocado trees performed 2x faster under your growing conditions and care! :-) I just checked out your avocado trees that you published--- LOOKING GREAT! Thank you for sharing your avocado growing successes!!! Charles :-)
I planted an avocado seed myself ,I think 6 years ago it just start flowering,I was a bit worried base on all these information about the avocado plant needing more than one plant in order to pollinate. Thank you very much ,your explanation now gives me new hope.
Where do you live? I'm planning on planting an avocado tree in my yard
And where I live the plants die from sun exposure it's gets hotter
Then hell.
Hi there, I have a very old Reed avocado on my property and would like to know, what is the best fertilizer and best way to care for it. it is over 40ft tall above the house. and can't get the fruit. when is the best time to also prune it, and will giving it a heavy prune. Like top off. effect the tree for the next season? as being so high I have trouble with the birds getting the fruit before it is ripe. thank you
Even though it's best to keep larger-maturing trees small than to reduce them, reductions to managable size can be accomplished over time. A skillful reduction of the tallest branches will let light into the center of the tree without opening it up so much that the bark will be sunburned. That light should encourage interior sprouting. You select and nurture those interior sprouts, and make sure that light continues to enter and keep them alive and growing. Continue to reduce the upper canopy in carefully-planned phases, all the while keeping the bark shaded, and only pruning off 20% or less of the total foliage annually. You could probably achieve the reduction you want in 5 to 7 years.
Great video. Growing several types of avocado in Texas. 🙏🏽
🙏👍✅ thanks for very very clear distinction 🥑🥑
Thank you for a detailed explanation of polination process, still have one question about it- how do I manage a successful polination process in a greenhouse with no insects, by hand? How do i know which flowers to collect pollen from in the morning and in the afternoon? Tried to make flies do it but it didn't work - they are lazy and not doing the job, and don't have bees in blooming period in my area🤷
A very well done video. Thank you very much .
My 3-year-old, potted avocado tree appears healthy, but has become very "leggy." Many of the branches are over 3 feet long, but they are bare starting from the trunk, and then lots of leaves near the ends of the branches. They are hanging low. I'm told that trees should not be allowed to bow down or even go horizontal. Should i prune these branches back?
I wonder how long pollen is viable. For instance if a bee or some other pollinators have some remaining pollen on their body from the day before, would it be possible that this pollen is still viable and can fertilize the ovary?
I planted two seeds from store bought avocados and they have take off but no fruit yet. I do have one I bought from nursery about three years ago but no avocados but it does flower but last summer took a beating from heat in Northen CA. Should I graft my seed growing avocados since they are big trees now and if yeast when should I graft it?
Excellent...Thanks for sharing!
I hv a plant about 3 yrs old not flowering yet . What to do,so that I get flowers.
What about grafting a Hass to a Furte Avocado ? Would that solve the problem?
So, I understand about open pollinated/heirloom plants and how they become a hybrid if they cross-pollinate. If I have just one Haas avocado tree, the seed would stay true correct? I could plant the seeds and they would 'come true' to the one parent plant. What an interesting plant! All assuming there are no other types of trees around. Is that what I understood you to say at around 19 minutes?
What about day 3 and 4. Will the pattern of day 1 and day 2 is repeated on consecutive days?
Hello ,Please tell me i have young tree and it flowers turn into black balls what is that when u pick it your fingers turn purple .what is male and female tree.
Very helpful information.
How to determine an type "A" avocado tree and a type "B" avocado tree without any labels on the trees?
Ya please elaborate ! As well as mine is not giving fruit for last 5 years
My avocado tree is not giving fruit since 10 yrs now so what will i do to that tree cut it and place graft avocado. Thanks
Any info on this yet?
Would it be possible to hand pollinate a type a ?
Info on avocados can be really confusing. Thanks for sharing such helpful info
What if you tie a bag around the bunch of avocado flowers? Would the pollen from the previous night/day pollinate the female flowers during the day/night?
Is there a way to determine the type, A or B, of a plant grown from seed?
If an avacado young has tiny black dots on the truck is that something to worry about? I would send you a picture but I’m not sure how?
Such great information. Thank you. The Cherimoya is somewhat similar but a bit more complicated to pollinate since none of the chirimoyas natural pollinators are in California. From what I understand the Cherimoya flowers are female in the morning and then become male at night. Since natural pollinators aren't here in CA, most people hand pollinate the Cherimoya collecting the pollen at night and then using a brush early in the morning to brush the pollen into a female flower before it dries up. The Cherimoya tree is actually fascinating. And the fruit is delicious and SUPER expensive (usually about $9 per pound). I have two baby Cherimoya tree in my back yard that I'm growing from seed. I actually just recently used your IVOrganics on ir to protect it and the trees are going great! Would be awesome if you did a video about the Cherimoya tree.
Hello Sergio Rios,
I love chirimoyas!!! And it has been my goal to grow the things that are (1) most expensive to purchase (so that I am getting the best return on investment in my garden), (2) most delicious eaten the same day (such as figs), (3) and just to make the most healthiest, freshest, most nutrient rich and organic foods to share with my family, friends and neighbors-- the foods you cannot buy anywhere else! I will be on the lookout for an area to squeeze one of these trees into my landscape. Great suggestion & thank you for that awesome testimonial! :-)
Charles
Hello Mr Charles! Your info on avocados rock! Also thank you very much for name Chirimoya, which it's it correct name,
no cherimoya! I wish the same would go for the Guayabas, instead of guavas! Do you have any plans for investors?
I'm wanting to invest in your product
Drop me a line
Silvia M.
Thank you, very very informative. I have two beautiful fuerte trees , thank you for helping me to understand this variety a lot more.
How are your fuerte avocados doing? Are they bearing fruits?
@@2013december, Yes, I now have 3 . I had a tree that was at least 65 yrs.old that was in terrible shape, so last year I stumped it , and this year it's producing two beautiful offshoots . God is good .
I have my 2 in semi sun. They don't get full sun. Here the temp. go up to 1005 in the summer. I'm trying to grow a second avocado in a container. It's growing beautifully but don't know if it will give me fruits.Great video.
how can we get you to train a group of young people in our District? Marvelous work!!!!!
Mine is a type B. It flowers like crazy but none of them turn into
fruits. Is there anyway I could get the pollen transferred from the male
ones (in the am) to the female flowers (in the pm) and speed the
process?
Great informational video. Wondering if anyone knows where I can buy some Hass avacado cuttings for grafting on my tree I grew from seed?
Hello Stela,
Thank you for the compliment! :-) Ask my friend Carlos, in Miami. Here is his RUclips Channel: ruclips.net/video/wg9T7rh2ed0/видео.html When you write to him, let him know that you were referred by Charles at IV Organic. Keep me posted! :-)
Charles
I am also looking for some but I live in Australia. If anyone in Australia can help me out I would love to buy some hass and other varieties too. I have bacon and fuerte I got from nursery but I want to graft onto my seedling trees I have at home.
IV Organic do you know anyone who will sell cuttings to people in Australia? I can’t find anyone sadly who will sell avo scions.
So, When the plant dies, seeing how full your trullis is, Is there a time your yard is left naked every 3 to 10 years? I realize you plant new starts, but how do you cycle them in? Several base vines? I am in Utah zone 7. Hopefully I can get a system that works here.
Very informative video i like it
My GreenGold variety is self fertile too
avocado Mexicola Grande it is type B or type A?
Help, no bees around and my 2nd year plants are flowering profusely. What should I do? HELP! Should I pollinate them somehow?
I have a avocado tree, I'm not sure what type A or B. My avacodo tree has lots of flowers, bearing only 1 fruit in last 7 yrs.
I would like to plant 1 more avocado tree, but don't know my current tree A or B? Please help. Thanks
Do A AND B trees produce the same amount of fruits??
Where is the bro have 9 avocado trees that I planted from seed. They are 1 year old this month and theyre about 1 ft to 1& 1/2 ft tall. A couple of them aren’t doing so well. I’ve been considering grafting a couple of them to see if that would revive them. Any idea where I could get some scions? And any advise would be greatly appreciated. Also I live in north Texas so we’re not so lucky with clay soil.
I have a avocado tree that is like 2 or 3 year old from seed that was given to me. its been in the ground for over a year now. Its now starting to grow pretty rapidly.(looks amazing) but I was wondering. because its from seed should I graft other varitys onto it? or just let it do its thing? I herd if you do from seed there is only a 20 percent chance of it producing fruit. Any advice???
I have a question. I have a 12ft hass avocado tree it has two main stems right up aginst eachother coming from the ground. Should I cut one? they are both healthy and thick stems about the same height.
My pinkleton is dying g up in Sacramento. Don't know what to do. Bought at Lowe and it's only been a month since I put down soiled. But my Fuerte and Beacon Hass are doing fantastically except for Pinkleton.
Pinkerton is not that cold hardy. You should replace the pinkerton with a more cold hardy variety like Stewart avocado.
sweettravellumkan Lowes has a 1 year free replacement as long if you have your receipt. If you lost your receipt they can look it up by your debit /credit card.
But my parents had only one avocado tree, 30 feet tall and it never got avocados for 20 years.
Could you explain why this would happen?
very very clear explanation sir, thank you
How do o know if my avocado is a or b , mine is a hass from planted from a seed bought at a store. Is an 8 feet tall now. It grow small in the yr.2013, then it froze that yr., then 3 more branches came out out that 1 tree. It's now 2020 and still alive but never have bloom. What type I need so this one cannbloom?
Can I buy a type B fuerte from the store and cut it off above the graft and then graft it to my hass? Or do I need to wait for the store bought fuerte to fruit first?
quite detailed thanks
not all flowers open at the same time?
29:00 would spraying stuffs on the leaves lessen the photosynthesis effect? Also, how often do you spray that? Do you spray again and again?
show me how to take care of an avocado booth when it first buds. I live in Vietnam, thanks.
Do atemoyas and cherimoya have a similar issue?
Why cant graft both type A and type B on same rootstock
Hello,good video for farmer who plant fruite plant, what do u mean by B type? A type,you mean does not need male and female plant at same time to plant?
I am going to say that I planted my Avocado from a pit, about 10+ yrs ago. I have no idea what type it is. It has never had flowers
On it. but we did find a small fruit on the ground one year, it had fallen off the tree. I've never found another one since. By the way we live in the deep South and it is hot here. My tree gets direct sun all day and I've never found any sunburn on my tree. It was a very big tree and one winter it got below freezing and died off, but started growing again in the spring. Is there a way I can tell what type of tree I have.
It sounds like it’s a deficiency 🤔 Do you use fertiliser or mulch etc?
Always feed your avo trees proper nutrition if you want it to fruit as early as possible
Wow great info in this video! Thanks!!!
Great video thanks for sharing all your knowledge! I live in Perth Australia and we have a type B „Wurtz“ Avocado for several years without any fruit so far. Since we are now in spring (September) I have some flowers on our Wurtz and hope for some fruit. After your A and B explanation I believe we would get more success by also having a type „B“ but we don’t have a lot more space in the garden and so I wonder if I can graft a type B scion onto a branch of my existing Avocado type A. Do you think this could work? And what would be the best time to do this spring, summer ...?
I would also be interested where and if I could buy your Sunscreen protection products in Australia if you’re selling them here.
Thanks for any information and happy gardening!
how far apart should avocaodos be planted?
That depends upon the ultimate size of the variety that you plant. The new 'GEM' variety is adapted to dense planting, but 'Fuerte' grows to be a large tree.
I grew saplings from seed in 2002. All were of same variety - Fuerte. After 8 years all three trees bore flowers & fruits.Apparently the trees were self pollinating. This season, in Mar 2019, I found that another plant grown from seed of my mature trees is bearing flowers for the first time - in 6 years. I found that an unsuccessful graft on its trunk had girdled the trunk at three places. I failed to remove the plastic wrapper! Also I had chopped off the upper part of the tree to keep it within 8 feet height. Could these action, by default, be the cause of early fruiting?
An evolutionary reason for the 'A' 'B' pollination schedule could be that the fruit is very heavy. Too many successful pollinations could result in the branches breaking due to many fruits hanging from it, thereby defeating propagation
Good information thankyou
My avocado tree produced a bunch of fruit last year but none this year while my smaller avocado tree is producing, not sure what is going on but any information would be appreciated. Love the videos!
Informative
Hi, i live in Huntington Beach, CA, zone 10. I would like to grow asparagus and brussel sprouts, but both of them are not recommended in my zone per one seeds website. Would you mind to provide your thoughts ? Thanks
I had an avocado tree was grow from seed for three years old. no flower .can you please tell me why my tree is not flowering? thank you in advance. I am staying in tropical climate.
Are Avocado Fantastic (Persea americana) self pollinated?
Hello Peter,
Yes. All avocados are self-pollinating. One tree is all you need for success!!! :-) Keep me posted on your avocado growing successes!
Charles
IV Organic thanks I love all your videos thanks for always answering our questions..
You're welcome Peter! I love hearing the positive experiences people are having from these videos... And I too learn SO MUCH from your feedback too!!! So thank YOU for the comments! :-)
Charles
Spiders also help pollinate flowers. There are a bunch of species that help with pollination.
Do wasps pollinate as well as bees?
Hello Tortaboy,
Yes. Adults feed on nectar... and in the process pollinate the flower. Wasps are also predators in your garden eating gnats, caterpillars and flies.... just to name a few. Check out this video I did not wasps last year: ruclips.net/video/MWmRiTjuPq4/видео.html Let me know if you have any other questions! :-)
Charles
My 10 ft tree doesn’t have flowers. It was. a seed my son planted after we ate guacamole. How do I pollinate it?
jill Lavinger Look for the tutorial that is called “Anillado en los árboles de aguacate”, I think you can watch it with subtitles in English. This tutorial shows a process of cutting a ring all around the tree that forces the tree to flowering and really works because I did it in my two avocado trees and worked!!
so march is aurtum ???? in australia its the end of summer
Great info 🌱🍀
Result of flowers ? Does it grow fruits ?
Thank you for a clear explanation of "A" and "B" avocados ... I got it! In the Central San Joaquin Valley, would it make sense to cultivate perennials that bloom and attract pollinators the same time that avocado trees bloom and what might those perennials be? Thank you , Stella from Fresno, CA
It seems like those avocados are planted fairly close to other trees. thought avocados needed a lot of space. Is planting a non dwarf variety 7-8ft adjacent to other trees considered ok? I'm wondering because I have about that much space left in my backyard :)
I feel like it's possible that avocado trees vary from one to the other in how their flowering happens. The way youre describing it, it sounds like the male and female parts of the flower are open and exposed at the same exact time on the very same flower. And that may apply to certain avocado trees. I'm not sure. But my understanding is that an individual flower will open and close a few times before it dies and that it alternates it's sex each time it opens. Meaning that the same flower will act as male during one showing and then act as a female the next and alternating back and forth until it finally dies. I will send you a link demonstrating the subtle difference between an avocado flower positioning itself as a female and then later positioning itself as a male. The flowers are so small that it's very possible one could miss this very subtle difference.
But after a certain time in blooming both type of blooms are open at the same time I have cica killer wasps approximately 2 in long on the avocado flowers they are nectar and pollen water I also spray my flowers with raw honey and distilled water brings everything
How do I identify what type of avacado tree I have?
Yeah! Is there a way to determine the type, A or B, of a plant grown from seed?
Fantastic
Great video! If I understood correctly then Type B avocados have higher chances of self-pollinating? For a single plant
Amazing 😍
