I’ve had dragonfruit plants potted for a number of years. My largest reached 3 feet tall (they are kind of a vining cactus) and was a huge pain to move each year (here in Mi it gets cold enough to kill these by mid-october). It was a pain to move because of its growing structure and because it leaves behind almost invisible tiny needles if one isn’t careful (and given it is a vining type plant I always got myself each time I moved it)
I had 3 of them for 4+ years. This year I lost 2 of them because with my recent rotator cuff injuries; I needed help with them and the temperature dropped a few nights more quickly than I had thought it would (mid-October). My youngest did help me move the smallest (2-gal) and I think it will recover…
I never got these to bloom (though I did get buds a couple times), nevermind fruit. They tended to be lanky unwieldy plants which have no problem putting out awkwardly larger growth on spindly thinner stems. The effect being that the plant needs to be constantly supported, at least when growing in my climate.
