For a number of years I've been battling this weed that my local Lawn Doctor can not solve. I'm hoping for some advice from this forum that can finally help me tackle this weed that keeps spreading across my Jersey Shore lawn more and more each year. Can anyone provide guidance as to what it may be and any advice as to how I may combat it... For August/September I plan to dethatch, core aerate, lime, overseed, and feritilize. Thank you in advance for any assistance!
