hahahah my bad Bugweed, I was initially seeing if there's a general answer.
But to be specific, they are watered with reverse osmosis from local supermarket, but recently, I've been using rain water collected from off my house roof--I know, it's risky but I accumulate so much more water that way than having buckets sitting out in the open. That's probably the reason for their deterioration, huh? I top water them as well as fill up their rubbermaid tray. Some pots are deeper than others so the big pots sit in about 2 inches, while the shallower pots are raised so about only 1-2 cm of the bottom touch the water.
And now for the rant: I'm this close to giving up on growing flytraps outdoors here in Houston, TX. There are just too many factors to consider. When I moved them in February from a classic terrarium indoors to grow under dappled sunlight beneath my trees, I was amazed at how vigorous they grew. Fat traps and deep reddening and catching all the bugs they wanted. However, as the summer approached with intense heat, I started noticing a significant slowdown in growth. The traps aren't as red and many wither before they fully develop. I don't see any presence of aphids or other pests so I'm thinking it's more of the way I'm growing them. What started out as a crown of 7 to 8 traps have dwindled to only 2 traps per plant on some. Several of these had started to develop flower buds but I had cut them off when they were around 4 cm in the hopes of conserving energy. But now even the emerging buds are withering before they push out of the crown. They're in pure peat.
Why is it that when I left them alone indoors in a humid terrarium under grow lights, they grew so much better? My sphagnum was pretty and stray sundews cropped up like weeds. Now I'll be lucky if I barely get one stray coming out of the pot. Of course, the only drawback I had was the presence of mold from time to time, but at least each plant had at least 7 to 8 traps! I think I just need to leave them the f#$$ alone. I keep moving them all over my backyard since I at first I felt they weren't getting enough light or they were getting pecked by birds (recently started hanging cds to scare those away). Ok, end of rant.
