I've got a D. binata that's growing well -- has 12" leaves, but at the end where it forks and is supposed to have little hairs and dew, it just sort of dries up. There are no leaves that can catch anything right now because of this. Any ideas why this is happening? I have my other droseras in small individual terrariums, but the binata's leaves are too long for me to do this with. It's inside, by a south facing window, no direct sun, and sits in a saucer of water.
