dj, my understanding is that they must have something to climb up, and then hang down, and that it is the hanging parts which form fruit, so anything at all that would enable it to climb a couple of metres or so should do it.

Thanks Pam. I guess it really doesn't matter how it's handled, as long as it goes up and then down.

There's been some voice that the pitaya will fruit quicker if in a pot, rather than in the ground. Is their some necessary concern about this?

How about water requirements; i've heard 2.5 to 5L a day! It seems a bit much. I have Blacksoil (lots of clay) and am concerned that too much water will rot the cacti. Does anybody have any ideas there?

cheers: dj.

I haven't had any experience with Pitaya itself, but have other fruiting cactus. They won't set fruit if they don't get water and feed when flowering. I would treat the Pitaya like any other vigorous vegetable/fruit, the more you put into it, the more you will get back. I really don't think rotting would be an issue. Joylene

Dragon fruit: if you grow it in a pot they only fruit till the soil is gone, but they wont die, the root of the plant will out grow in a pot. once the soil in the pot is gone can't really put soil in it. to have fruit faster, best plant in longer stem, the pole should only be 1.5 meter in Height, as they wont fruit untill they start to over hang. Dragon fruit is like a Cactus in the desert, they don't need 5L of water everytime, in winter I only water it once a week. in summer everyday in the morning.
