Q: Winter dormancy? Huh? What?

Dionaea
Mugly!
A: Now just because your plant is stopping in growth and not doing very much, it may not be dying. It might just be entering its autumn dormancy! There is no doubt that a Venus flytrap entering dormancy can look pretty miserable (look at the weatherbeaten plants to the right), but this is all part of life's magical cycle of renewal.

I get so many questions about dormancy and Venus flytraps that I want to be very specific. So pay attention!
