    Hi guys,

    A commercial area for my mother was recently transformed from dead grass to decorative gravel. The grass was totally dead so they put weed blocker down over the grass(i know it should have been removed) and laid the gravel. Got a few big rains and the grass has been revived! I sprayed some weed killer on the spots, but is it going to work considering the blocker is there preventing it from soaking in good? I used the groundclear stuff from Lowe's. Also, how close is too close when it comes to the trees? Only trees there are palm trees and supposedly there roots go straight down. Any thoughts?

    All grass/weed killers that I'm aware of work by sticking to the leaves of grass/weeds and are absobed that way and kill the root. Any pre-emergent (I'm assuming that's what was used to block weeds) only stops seeds from germinating. Also, as long as you don't directly spray any desireable plants they should be fine. Hope this helps. :waving:
