Hi, I contacted you last year about several issues in my ground cover juniper bushes. You suggested Snapshot and that helped alot. My problem is I also have crabgrass in this ground cover and while it controlled most weeds, it didn't help at all with crabgrass. Is there another product you can recommend that I can use in addition to the Snapshot that would be better for the crabgrass? I don't want to kill the ground cover just control weeds and crabgrass. What is the best month to apply the pre-emergent for east Tennessee? I think last year I spread it at the end of March.
Fusilade is a good option to use for crabgrass and other grassy weeds in juniper as directed on the product label. As far as timing for a pre-emergent like Snapshot, it should be applied before soil temperatures reach 55 degrees. If the Snapshot did not prevent the crabgrass it sounds like it was applied too late. You may also contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.
