zone 9, 2 years and no fruit. :(

Do you have GH? They not only need to be mature, but they need lots of heat and sunshine to bear fruit = long summer.

I got rid of my plant after having it for nearly 3 yrs; it takes too much space and they are prickly!

(Btw, why don't you add your general location and/or growing zone next to your name as others do...)

Yes it's in the greenhouse from April-May till Oct-Nov There were a few small cuttings in pots I left in there all winter. They did fine till end of Jan when they either got too wet or the few nights of cold got to them. The greenhouse is probably zone 9a/b. Leslie is yours in a pot or ground?

Rina, thank you I will find out how to update that. It gets a long season

I planted mine in November and got fruit the next summer. Call me lucky!

For most people however it takes at least couple years to get any fruit.

Most of mine are in the ground. Two are from tiny cuttings I bought on ebay - they have rooted, but only about 12" tall. One was in a gallon container, and it's only about 2' tall right now, but multi-branched, which is probably its problem. Two others were cuttings from a neighbor, too new to tell. My most promising one is the tallest, acquired as a scrap lying on the floor of a nursery - he's in a pot outdoors, and is about 5 feet tall.

It took me five years to get fruit - mine it outdoors in an extremely large pot, but it is nearly impossible to move the pot at this point, and so it might as well be in the ground. I got five flowers last year, and I only pollinated one of them successfully. You have to hand pollinate the flower (it can be self-pollinated) within a couple of hours of the flower opening - if you wait until the next morning, it will be unsuccessful. My flowers opened up about an hour after sunset, and while they stayed open until about 10 the next morning, the pollen was no longer active.

I had a lot of pitaya juice on my recent trip to Brazil, and it was fantastic - I just got back last week and plan to post some photos of the botanical gardens when I get time.
