Black Medic Weed on Lawns

What Is Black Medic?

We received an email the other day asking about the best way to control the weed Black Medic on a home lawn.

Black Medic (Medicago lupulina) is a difficult-to-control weed due to its small leaf size and the waxy cuticle on the leaf that reduces the absorption of typical weed management products.

It normally takes 2-3 applications to start reducing the prevalence of the black medic weed.

In the meanwhile, the most important parts of weed management are fertilizing the lawn to crowd out weeds and thicken the lawn, proper deep watering (as weeds invade weak lawns), and mowing properly and often. (Mowing also helps thicken the lawn. Plus bagging clippings when the weeds are in flower helps as the flowers produce seeds creating new weeds to contend with.)

“I switched to this company years ago. The previous company we used burned our lawn yellow. Lawnsavers has brought the lawn back to life, and the weed control is great! I would highly recommend this company to anyone. Also, they use environmentally-friendly products. Based on the reviews I’ve read what others have said, I decided to give Lawnsavers a chance. I am glad I did!”

    2020-21 important turf and tree high (and low) lights:

      • Nine days of snow, ice and wintry weather in May 2020
        2021 was the driest April May and June in 51 years See Actual GTA daily weather records by clicking here.
      • One of the hottest driest summers on record in 2020 with long spells of grass-killing heat and drought. Read more here in our 2020 summary blog.
        2021 carried on this trend with only a few days of rain in July and August, with extreme dryness and heat.
      • A bumper crop of crabgrass that germinated in the perfect (rainless) storm. As expected, even more arrived this past summer in 2021!
      • Chinch Bug numbers in 2020 were record breaking and persisted through the dry heat they love, secretly killing lawns while dormant! We can help with Chinch bug damage  Expect even more this summer!
      • Fall of 2021 provided excellent conditions for lawn that were treated through the summer with our recovery amendments to bounce back and regain their vigour. (thanks for the compliments!)
