I'm so glad I sprinkled the sevin on the seedlings! So far, I see nothing going on, and the seedlings are looking great! I left it on them for 4 days. We'll see if that is enough.
I took them outside today, since it was kinda nice, and rinsed them off. I didn't deluge them, wanting the sevin to sink into the top inch or so of their soil. Crap
I forgot to take pictures (so much going on)! I will next time (if I have to do it again)!
