I love my Venus Fly Trap. But I stuffed up and hurt him bad. For some time it has been getting black leaves. I was told he wasn't getting enough sunlight. So I put him outside on a 32 degree day and he was burnt. It had 12 healthy leaves, now it had 3 left that are deformed. This is what I have learnt. Give him as much light as you can with shade and do not move the pot again. Feed it once a month with one fly and water with distilled. Give him a little bit of water each day during Summer, but don't wet soil too much, just make it slightly moist.
