I have been watching this thread and have seen that a lot of member have gained a lot of experience in the last 4-5 years, Now I need some advise.
I'm exploring dragon fruit as a plan B for my avocado grove may be only partially. 2-3 acres out of the 20.
I want to star experimenting in the cultivation of dragon fruit. I'm removing some citrus I have with a length of 100' and will have at least 15" on each side.
What kind of set up would you do, how high and what materials to use.
What varieties would be better for Homestead.
Planted on the ground or in containers?
Also I have two concrete container in the corners of my patio at home. They get a lot of sun. Seem like a 20 gal capacity, they weight a ton. Pictures attached.
What type of support would you use on these pots? What varieties would you plant? Soil to use?
Any help would be appreciated, including rooted cuttings I can buy.
IMO, containers are always the best way to go. 15 gallon minimum, 20-25 if you can get them cheap. You don't want to fill them more than 75% capacity, and you want tp make sure they have proper drainage. Larger containers will allow for multiple plant starts per: 15 gal for one, 25 for 2, more for more, etc. Soil should be loose, sandy or gravely, and have something mixed in to help retain moisture without getting soggy. You don't want wet soil, but you don't really want extended periods of totally dry soil either. I try and use 1 part garden soil, 1 part coarse sand, one part bark nuggets (as small as you can find) and whatever else you can afford to toss in after that (peat moss, perlite, moisture control crystals, etc)., depending on your budget.
As for what type to recommend, lets start with why you are growing them. Are they for you or do you plan on distributing them? Some look better than they taste, and some taste better than they look. If you're going to fruit stand them, Id suggest something flashy like a bright white Vietnamese Giant or a fuchsia American Beauty (or both). If they are for you, then you should plant to taste and not worry so much about glamorous looking fruit. Either way, youre going to want to make sure youre growing more then one type to help with pollination.
Structure-wise, the standard post and cap is the simple solution. My version of that is to take a 4x4 post of (non-toxic) treated lumber, wrap it in a couple layers of burlap (potato sack material), tack the wrap in place and then bury the post 2ft to 3 ft in the ground. To make it double water resistant, you can paint a layer of roofing tar over the area that's going to be in the ground before you plant it. Once your post is in place, you need to add supports to carry the weight of the branches. Ric has one example of a solid support setup in his pics. Another is to just attach heavy steel mesh, the type they use in concrete slabs, onto the top of the post. You can also drill a few holes through the center of the post and run rebar through so it sticks out 3ft on each side (cover the rebar in plastic pipe pieces if you do it that way). Or you can do a combination of any of this. ive seen people attach bicycle rims on top of posts. Some people don't use posts at all, and go with trellises or full rows. There are a lot of ways of growing the actual plant. I would suggest going on YouTube and look up Dragon Fruit and Pitahaya, and see how other orchards are doing theirs, and get inspiration that way.
Hope this gives you someplace to start.
