Denise, move. :) I suppose california might do it, south and central america would probably be better though. Hylocereus likes a lot of room, if you're growing it as a house plant getting flowers out of it may quite a task. If you want similarly impressive flowers from a somewhat smaller plant look at Epiphyllum oxypetalum and some of the white hybrids. Oh, or Selenicereus grandiflorus. Hylocereus is much loved by slugs, one of my ravaged seedlings was in such a state i had to cut most of it down, they are extremely good as rootstocks for grafting though. The aforementioned slug snack had a small piece of peanut cactus (these days known as Echinopsolobivia chamaeceresylvestrii or something along those lines ;) ) placed on top and it had definitely taken after just 1 day.

I am looking for Jambu Wax Plant or Seed. I have Dragon Fruit plants and cuttings to trade. Plant is about 10 inch, very well rooted. Also have punch of cutting. Plant is self polinated. fruit is large up to 1.5 pound. Red/pink outside, white inside. Please email if interested.

Another day, another plant woe... I thought dragon plants were indestructible but mine is looking peakier by the day. Its leaves are turning brown, and I don’t understand why - I water it when the moisture sensor tells me I need to (when it’s dry down to maybe a cm or two), and it’s near a big south-facing window. What am I doing wrong? (Houzz is not letting me post a photo right now for some reason but I will try again in a bit)

The moisture meter doesn’t work. Those things only measure salts and not actual moisture. Get rid of it and use a wooden dowel sharpened at both ends. Stick it in the soil all the way to the bottom (don’t worry about roots) and pull out and inspect. Dark, damp with soil stuck to it = don’t water. Nearly clean and dry = water. Does the pot have a drain hole? If not, make one or repot. You're not flushing the soil enough and salts from the water are building up. Water the plant next over the sink and flush the soil with about 10x what it takes to saturate and come out the drain hole. You're water is high in fluoride. Try collecting rain water or use distilled. You're likely over watering if you’re soley going by the moisture meter.
