My Den keiki is growing roots!!!
 

I just noticed today that my little Den keiki started a root... roots are good. I'm so excited cause this means it's happy. I'm a bit worried that the keiki is too small, it's only about a half an inch. Now that it has roots should I mist weekly with a weak fertilizer solution?

If it looks healthy and happy, it probably is. I'd just let it grow.

Congrats!
Sounds like it's happy. I would just leave it until roots are at least an inch long.
