>>2120488>>2120669Growing dragonfruit in a pot here in 6a. I'll regurgitate what I've picked up plus from my experience with it so far.
>StartingGet yourself 2-4 cuttings of your desired variety and start rooting them. If you feel like starting it from seed, go for it just be prepared for it to take literal years. I personally am not going to mess with it until I have multiple plants and I can cross-breed them. You should root the cuttings in whatever soil mix you're going to use for the big plant, or you can root them in water with a seedling heating mat. I did 2 cuttings rooted in soil (but used rooting hormone) and 2 rooted in water with heat mat. The water cuttings sprouted roots first, but picrel was the first to grow a new branch and was in soil so make of that what you will.
>MaintainingNaturally I haven't had to do too much to my cuttings, but because I used a high quality soil they won't need feeding except for every 6 months and I keep the soil about as moist as any other well-draining soil. You don't want to bog it down with water, but because it is a fruiting orchid cactus it does actually like more water than your standard set-and-forget cacti.
>ContainmentBecause I want my soil to last for a while as well as give the plant the best chance, I'm going to eventually transfer it to a 25gal nursery pot. Yes, this is a tree-size pot. You will have a tree-size cactus. You will need a trellis/support for the cactus cuttings. I advise simply looking up dragonfruit trellis designs, but you will need to build one and insert it into the pot so you can place your cuttings on each side of the center post. Wrap the center post in something like burlap to help the cactus cling as it climbs, and secure it to the center with stretchy gardening tape.
Hope this helps!
