This past season I had a lot of annual bluegrass. During the spring I tried to remove as much as possible by pulling and digging up patches. Additionally I kept the grass at a longer height and removed as many seed heads as possible in between mowings. I heard putting down a preemergent treatment in fall can control this grass. What products are recommended. When would I apply it ? Also can this treatment control crabgrass if put down in the fall.
