Lawn Weed ID

Asked June 20, 2020, 10:10 AM EDT

I recently bought a new home in the Salisbury area Aug of 2019. The lawn has become heavily infested with black medic and this other weed that I have not been able to identify. The small subdivision (12 homes at present) are being built on what was once a small farm and all the lawns have deteriorated to the point that very little turf grass exists. The neighbors have a practice of scalp mowing their lawns at about 1 to 1-1/2 inch which has over a couple of years resulted in the black medic and this other weed predominating and choking out the lawns of healthy turf grass. A remaining 10 lots is heavily infested with many types of weeds and serves as constant feed of new weeds I believe. Can you tell me what this weed is so I can better understand what I'm dealing with. Thanks

This looks like Rabbitfoot Clover (Trifolium arvense). This is not your typical lawn weed. Please see the following link, https://www.marylandbiodiversity.com/view/3854
Scalping a lawn does encourage weeds. The mowing height for tall fescue is 3-4 inches. To improve your lawn you should start with a soil test. You probably need to do total lawn renovation. The benefit of that is you can incorporate organic matter into the soil.
Please see our information on soil testing and lawn renovation.
Tall fescue is the recommended turf species but zoysia would also do okay on the eastern shore. Also, consider lawn alternatives for appropriate areas in your landscape if they exist.
