Dragon Fruit in Containers

[gwrace]

I recently received some dragon fruit cuttings and seeds. I plan to grow these out in containers with some type of trellis system. There may be  few nights each year where these may need to be moved into the greenhouse. The objective is a fair amount of fruit production. What have you found to be the optimum container/pot size so these plants will fruit? I currently have several types of tropical fruits growing in containers but none require trellising or use areal roots like these cactus. Would appreciate any tips or helpful hints.

The container size depends on how much fruit you want, a 25 gallon on wheels is good to move in and out. And you would get a good amount of fruit.

I read some where that dragon fruit roots are shallow.

I'm no expert, if some one can confirm that would be great.

If true would a 25 gallon in a wider pot be better (if they make it) then the traditional 25 gallon nursery pots?

Yes the roots will tolerate shallowness and the plant will not be stunted. I'm not sure what's the maximum they will go but 1.5-2ft deep seems okay for me.
I use wide storage containers for my plants but should have used something that's UV stable so it doesn't degrade as fast.

I agree with markee.

You might want to used plastic 55 gallon drums cut in half (two containers) for pots.

Mount the half drum pots on wood base with wheels.

Building a good trellis might be a challenge.

I grow Dragon Fruit in pots because of gopher problems, but do not have to move the pots.
