I live in NJ, and have a crabgrass problem this year. I'm not sure what to do to be crabgrass-free next year. Normally, I just pull out the clumps by hand. But there are too many now.
Should I just keep persistently removing by hand/shovel?
Is there something I could spray?
Should I just let it be and use a pre-germination preventer in the spring ?(like I did this year... )
Any experience or insight appreciated.
