Dangermouse ... very admirable work with your dragon fruit plants!
I'm starting over at a new place. Here you see an American Beauty cultivar planted in a 25-gallon pot with a cactus/palm soil (Kelloggs, if you're on the west coast). This is on the east side of my home and the trellis is about 18 inches from the wall of the house. You also see a 1/2-inch irrigation system with two streamer-type heads for the pot. During the summer here it comes on twice per week, twice per day for 4 minutes. Yes, I know I build like the 3rd little pig. But I got tired of going out to visit one of my plants and find out its dying because some rat or rabbit had chewed through the cheap rubber irrigation tubing. When you have 210 cherished plants, you just can't afford maintenance interruptions.
