Wow! Lucky man with a beautiful mango tree! 😍 I just saw two mango trees in the area of Redwood City ca and Palo Alto ca, just one survived, it’s 4 years old, fruiting from his second year. I am making videos about mango trees as well!
Pittsburgh is 9b on Hardiness Zone Map. You can play around with mango trees up to 9a, so yes, you can plant them even above 37 degrees North if you find the right microclimate.
I have a sapling that started in my compost bin. I have it in a 5G pot and it’s about 6in right now. It has around 8 leaves with some new growth. I live in Chico Ca
I’m growing mango tree in the same area with my avocado trees in Sacramento Elk area, let see if it will survive this coming winter. Both of my avocado 🥑 one from Lowe’s and one from nursery and they survived winter of last year, today I have 6 avocado 🥑 awaiting to be picked..not sure if I should pick but I’ll wait for the right moment since it is now the season to pick 😆nervous 😆
I'm in San Jose too. I don't remember the name of the Mangoes I bought - but I got them from a local Indian grocery store. I know they were not any Indian variety. I think they were called "Kent". Very sweet. I sprouted 10 seeds from them...and hoping they will live :-). Try any Mango you can buy from a local grocery store. Just make sure they are well hydrated always. I hope we both are successful in our mango-experiments.
You can grow it from seed and some mangoes will actually come up true to type, but often times not sealed likely end up with something inferior, but truthfully, even inferior mangoes are delicious. One problem with sprouting them from seed is that most of the fruit that comes in from outside our country gets heat treated, and it kills the embryo so often times they will not sprout because the embryo is dead. Grafted trees ensure getting exactly the plant that was utilized for the graft.
@@aleem076 yes try it. I’m not a professional but I feel like California has good weather to sprout the seed but when it come down to growing the actual mango I’m not there yet..
Alan, I'm in Evergreen, San Jose. I've sprouted a few mango seeds. Do you have any tips on how I can grow it here? last time I tried it grew a few leaves and then died.
@@ThePurpleFlower My mango tree is still doing good. I have another 6 leaves starting to sprout. It needs to be watered every day if it is outside Mine is outside in a pot.

OK, this is an official competition. Please send me a picture to gary@goldengatepalms.com. I'd love to see it. The mango farthest from home. The World's bravest mango!
@@Valterxicao I have them north of Braga. It all depends on the varieties. Osteen, Kensington Pride, Sensation, Keitt and some others, that flower after the end of March can grow very well here
@@Atimatimukti Show me photos. One thing is to have small trees and protected from winter, another is the one that is in coimbra with about 3 and a half meters of height and 4 meters of canopy ... completely unprotected of winter. I have some trees in the street in the zone of leiria, I have a tommy atkins grafted in the street with 2.5 meters of height
@@Valterxicao My trees are small but I do not protect them in winter. If temperature goes below 4.4ºC when they are with flowers then I protect them. But I only have varieties that flower from April on so very rare if not impossibe to get those temperatures here. Besides, I have a micro clima here in Vila Verde. In my farm, temperatures can be more than 5ºC hoter than farms around. No ideia why this happens but being well protected from north winds can be a major fact. I also grow avocados, macadamia, anonas cherimoia, pitaya,white zapote and sapodilha besides the more comon ones. This year I will try the Ora Pro Nobis from Brasil outside the greenhouse. Sugar cane grows very well (almost a weed :-) )
I need some scions from this tree did you cut some:)? Horn like end-shape of the fruit resembles me of a south-east-asian variety, but dont know exactly. I am from Europe zone 7/b, i am a 20 g pot grower, but i know that people grow them in Sicily(Southern Italy)with success, comercially too. (Kensington Pride,Glenn, Tommy, Keitt) Oranges, Avocados, Pomegranates Rome/Italy downwards close to the coast. Turpentine mango grows and fruits on the French Riviera, also some citrus on the french/italian coastal border. Some people try to grow mangoes on Sardinia, Mallorca, Corsica with more and a less success. Southern Spain is the warmest in Europe, a bit warmer than Sicily, there is a greater production of mangoes in the Malaga area. East side of southern Europe like Greece or Cyprus grow also some mangoes. Outside of Europe Israel for sure. Thanks
My tree is a 4 years in the ground tree. Will not grow big due to turpentine root stock. I see it as a bonsai and is very happy that she bears huge fruits (longer than a dollar bill). Will be harvesting them end of September and eating them green. Thanks
@@StanTheObserver-lo8rx Hey Stan, I'm in Hayward too. I'm growing a Glenn Mango. It's in a pot until I figure out where to plant it. It survived last winter with no protection. It's about 4-5ft tall. Heard Glenn is a hardier mango. It fruited for me but the fruit fell after getting about the size of quarter. Better luck next year.
@@StanTheObserver-lo8rx Yea, living near the bay adds that humidity and sort of a shield from any potential frost. Gives me hope with growing all my fruit trees.
@@StanTheObserver-lo8rx I'm searching on google maps for that Mango on Tennyson near the Rotten Robbie. Is it over by the apartments next to the gas station?
Southern Spain is commercial mango growing area and further north. But it's possible even further north along the coast of the Mediterranean Sea, maybe up to 42° N as an absolute maximum.
Hello, I am your neighbor in Antioch, California. Are you growing any other tropical fruits like guavas, lychees etc.? Could you please recommend a mango variety that would grow well in zone 9b? Thanks!
Well, it seems that I am going to have to add Mango to my list of trees to get planted and growing! I have a lot of Moringa going right now (50+), 4 Fig trees waist high, and 3 Apple seed grown trees to graft known varieties on. I'll leave a branch to be able to see what the seed tree produces for fruit! Who knows, right?
I’m in Oakland, too, in the banana belt (by Mills College). My main concern with putting it in the ground is all the clay we have here. Bad for the roots. But if you prep your soil enough, it shouldn’t be too bad.
I have a few (one in the ground others in pots) in Chico, but they haven't experienced a winter yet. Gary has a newer variety that's supposed to be the most cold hardy yet, I'm hoping to get one on those.
@@jmart5302 Just entering the cold season so we'll see, few mangos in pots one in the ground all doing well except for one which has never done much. Dozen avocados in the ground for over a yr. most are doing well some thriving with a few maybe ready to carry fruit in a yr. or so. I may put out some heat lamps for a few things any day now just to get them past few coldest hr.s in a night.
@@vicentebarragan2336 I've got several but only one in the ground which got hit hard one time due to an unexpected first frost, one in pot is looking bad other OK (rated as more hardy but it's never grown much for me either) I had heat lamps for cold mornings except that 1st frost. For comparison my less hardy avos--Reed and Wurtz took just a little damage on top but they too had some thermal protection from below too, virtually no damage on another dozen more hardy avos.
Are you kidding? I have mango trees at 41º 43' N in Portugal (and a lot of people here also) and you are at 38º 01'N. It depends on the variety. The problem is not so much the temperatura in winter but the temperature as soon as they go in to flowers. So get varieties that flower after April and give fruit before November and also, dward ones that you can cover easy.Trees can get to -3ºC but flowers and fruit die with less than + 4º 4C (sorry, no Fº)
Do you know the variety of mango you have? I am a plant breeding student and eventually want to return to California and try to develop tropical fruit for northern climates. Portugal sounds like it may be a good place to collect seed.
@@toddanderson7484 Osteen, Kent, Keitt, Tomy Atkins, Kensington Pride, Irwin, Palmer and Sensation. The more dificult from this group is Kensigton Pride from Australia because it very prone to anthracnose (we have a lot of rain in the northwest of Portugal)- Kent is also very susceptible to hunid conditions
I'm convinced that most of CA(especially coastal) is capable of growing the most tender of vegetation. Even coastal areas as far north as San Francisco. Am I wrong? I'm just going by the palm trees that I've seen growing there and using them as a barometer.
The Bay Area has the second most complex micro climate in the entire World next to the tip of South Africa where there is similar geography but with a tropical ocean on one side and a cold ocean on the other playing tug-of-war with each other. And what you are saying is true although generally the closer to the coast you are the more frost free it is but the more cool the climate becomes. As you move inland, temperatures increase but so do freezing night time temps. There are microclimates inland that buck the trend and are warmer and also frost free for various reasons but generally as you leave the coast the heat increases but the vulnerability to freezing temperatures also does. So it all depends on what you are trying to plant and knowing exactly what you can get away with any given micro climate within the Northern California microclimate.
I don't want to be that guy but... I've seen mangos outdoors growing in the south of France. So ya probably that mango is not the northernmost mango growing outside
Their secret is they are from India, grew up with mangos, and just planted a small plant just like you or I would plant an Apple tree. That simple. They thought nothing of it.
@@ScaryHairyGary That's all?? I'm Indian too and grew up with Mangos all around. Now I'm in San Jose. I will go inform all my sprouting seeds that I am from India, they must grow for me. :-D
