- In this video we show you how we collect seeds from our plants, provide tips on how to propagate them, and best practices to prevent rot. Every species is unique and requires different conditions to sprout, and even then nothing is guaranteed. Growing cactus from seed can be a slow but very rewarding process. We do our best to show what has worked for us in the past and hope it helps your seedlings as well!

That is the coolest dad ever
very nice tech. the most valuable lesson i see here is to be continuously sowing seed to keep up your skills and adjust tech as you go. i sow infrequently and can't remember how i did it. it is good to be able to review the procedure and materials before i start, and gives me confidence i won't make a foolish mistake.
Hi!!!! I just bought some Lenta seeds from y'all & I am Sooooo happy & can't wait to receive them! Am I allowed to say that??? Anyways, I was going to try y'all's method this time! I have a question pls,,, you said u use JUST pumice & sand for ur mix?? That looked like very fine sand. Won't it just fall through the pumice to the bottom??? Also, did I hear right, did u say you just were using Beach sand??? All I can really find is All-purpose sand or course silica sand??!! But I Also found a small grained akadama! I wonder how that would work?? Isn't that how the folks on the other side of the world use?? These are my questions!!! I would sooooo appreciate if u would get back to me, hopefully soon so I can do this with the Lentas!!! I sure do love y'all's videos!!! I especially love the Father-Son team!! Y'all make a great team!!! Thank you so much. Sincerely, Anita 🌵
Hello, we would be happy to help. We use sandy soil primarily from the Mojave desert and pumice. We do not use beach sand and primarily use sandy soil. This sandy soil has a mix of sand soil and might have some clay. Both all purpose sand and silica sand will work but I would guess silica sand would work better. Akadama is useful but expensive so we don’t use it. Turface is a good alternative and is cheaper and so is floordri, so long as it’s high fire diatomaceous earth. You can find floordri in auto parts stores because it is used to suck up oil but works well with plants. Just make sure your soil doesn’t grow mold! Best of luck and hope you enjoy the lentas!
Hi nice method,
I just quite a similar one here in Madrid Spain (dry Mediterranean climate with hot summers reachin 105F in July-August). As you mentioned it is much easier to keep control of fungus and the plants are quite hardy, my seedlings seem to deal just fine with drought, sun hot and cold climate. However, I have noticed that after 6 months or so, the growing rate decline, then I start to fertilize but still they groth seems a bit slow to me in comparison with one can see with other methods.
Further with the baggie method, I believe that it can be useful for a small number of seeds, or some really valueable or delicate, but not as a general method (also instead of recycling plastic you have to buy the baggies). Also I experienced that not all species like to be in a moist environment after germination (Saguaro, Coryphanthas, etc.) and other genera do quite well under those conditions (Frailea, Turbinicarpus, Astrophytum, etc.).
I would like to know the temperatures that you are reaching there.
Hi MCactus, Similar climate. Spring now about 25C during the day and maybe 12C at night so still bringing the 1 month old seedlings ( plus I just started more ) inside for night and putting on a heat mat to get all the seeds to germinate that I can. Summer temperatures maybe 80-90F during day and 65F at night. I think exposing small cactus seedlings to drier conditions will slow down the top growth but you'll get better roots. Ever buy a big fat cactus from a nursery and find there are almost no roots ? That's how you grow cactus fast- all heat, water and fertilizer and a good chance of a plant that goes into a growth check once out of the greenhouse. Anyway I take the plastic off at night and put it on during the day if its warm and dry to acclimate small cactus to drier conditions and getting the roots to grow. Bottom water useful at this time encourage roots to go deep. Plus keeps fungus away .
have you ever tried captan? its a powder fungicide. i mix it into the water that i initially water the soil with for prevention. but you could shake it on with a brush or pepper shaker. i do notice that it knocks back mold growing on fallen, dead pereskiopsis leaves. so maybe it could be used for treatment but I can't say either way. a little goes a long ways. that's why i mix it into the water in the first place. it only takes 24 hours for mold to grow.
I’ll have to check it out! Thanks!
New to the channel and growing from see. Absolutely love the videos. Do you have any recommendations on where i can purchase material for soil. Thanks guys!
You can pumice "aka dry stall" at feed stores. Don't buy stall dry. You can also use Turface. This will make up 1/3 of your soil mixture. Course river sand from wherever you can find it will make up another third. The final third we use granite based sandy soil, usually from the desert. Or you can get decomposed granite from a building supply store. Premade bagged soil from garden stores tends to not work. Hope that helps!
Amazon is where I get most my seed & cactus minerals from. Although, last I checked, they had zero surface, no sandy material for making the substrate. And Amazon claims to be the cheapest but they really aren't any cheaper then most stores. But I live out in the boonies so I don't have much choice but to buy everything online.
I just throw them in sealed tissue culture cups. Often I get undifferentiated callous tissue instead of seedlings, which I can initiate into way more plants.
Very interesting video. You grow your cacti in a pretty spartan way (similar to the natural conditions I suppose). How often do you fertilize your seedlings, if at all?
Best regards,
Nino
Natural conditions are much hotter and very wet for short periods of time at least for the desert species. Most of these cactus species need heat and water to fool them into thinking it a Desert monsoon in March in a coastal climate where I live. After the plastic heat dome and heating pad its a cooler Mediterranean climate they grow in that doesn't really get warm until July so they need to be drier than they would be in a desert. A little easier to germinate in July but I don't get much growth before Winter dormancy and if the seedlings are too small they don't do well over Winter. They will get more water in July when its hotter at night and some Fertilizer at that time . Regards K
Love to see the different techniques but that is a lot of work bringing seedlings in daily. The baggy technique on a heating pad and fluorescent light is much easier (faster?) although fungus is at a higher risk. Keep the vids coming.. Happy growing!
@@bonbahmerdealors Baggie method is popular but I have this crazy urge to check on them daily with a 4X loupe so I would be taking the baggie off to see them and that sort of defeats the purpose of a sealed bag. I usually just start 6 pots at a time and after a couple months they are outside day and night to harden off. I plan to try some strombocactus and they are so small I probably will need to use the baggie method sealed up for months. Thanks for the comment K
@@kes1171 I just had successful germination with Oreocereus celsianus seeds that I had in the fridge for at least 5 years. The seeds germinated within a week at about 18°C on the normal gritty substrate that I misted from time to time. I didn't expect success honestly due to age of the seeds and lower temperatures but seeing that it is a mountain dweller it makes sense.
i had good success with captan fungicide
Thanks, I’ll check it out!
The cactus at your local garden center are full of blooms. Do they spray them with something to make them have four blooms per plant all at once?
We don't spray our plants with anything to get them to bloom more. What other garden centers do, I'm not sure. I would imagine though plants that are on display for the public are probably tended to very carefully so as to display their fully beauty.
Do you fertilize them?
No, we don't fertilize them until they get older
Use bacteria to prevent fungus. There's a cheap product called "garden friendly fungicide" or Impello Bioscience's product "tribus original" which is more expensive (but will benefit the cactus growth rate)
How do u use it?
Thanks to yputube algorithm
