Dragon fruit in ground vs pots (SE Florida)

[dross99_si]

We're new to dragon fruit growing and see so many people keep them in pots. Is it not good to just put them in the ground? We would be growing in zone 10a SE Florida.

I don't think there is anything wrong with planting them directly in the ground as long as your soil drains extremely well because dragon fruit prefers drier soil.  We live in South Lakeland and unfortunately our soil does not drain very well so we have ours in pots with a trellis inside each pot. 
Hope this does not offend anyone but there is another spot with great information on dragon fruit with a number of participants that live and grow dragon fruit in Florida and that is on Facebook, Dragon fruit growers of North America.  A moderator there, Michael Floridino, has a significant size farm in Central Florida and is also a wealth of information.  As you plan to start, if you are doing anything of size, it might be worth trying to arrange a trip to see his operation.
Best of luck to you and I look forward to seeing posts of your progress.
