Crabgrass - Knowledgebase Question

Fairfield, NJ
Question by mydollydolly

I hope you can help. I use the Scotts 4 step system for fertilizing my lawn and I have applied steps 1 and 2 already. I also applied the fertilizer with Iron as an extra step. I am growing a ton of crabgrass. It happens every year to me and I can't get rid of it. It's coming up again this year. How do I get rid of it once and for all. Thank you, Karen

Crabgrass is an annual weed that dies out every winter and starts anew from seed each year. It can be prevented using a pre-emergent crabgrass preventer such as corn gluten in the very early spring (when the forsythia blooms) and then repeated later per the label directions. You might also want to consult with your local Rutgers county extension to make sure this is crabgrass and not something else. You could also consult with them as to the best lawn maintenance procedures for your lawn becuase your best defense against weeds is healthy turf. This would be based on running some soil tests and determining optimal fertilization and pH, as well as correct mowing practices. Good luck with your lawn!
