| if i put down round up weed killer, do i have to wait and remove the thousdands of weeds before i put down the pine needle mulch? or can i place it down immediatly? |
| Once the weeds are dead you shouldn't have to pull them - but there is a chance that there are still viable seeds so removing them might be in your best interest. Most people don't though and just spread mulch over the tops of the dead weeds. |
