Pet friendly weed control for the lawn

Asked August 27, 2019, 3:49 PM EDT

My 5,000 foot backyard which is 50 shade/ 50 sun and is turf type tall fescue has become overrun with weeds...clover, broadleaf, crabgrass etc. I do not use chemical weed controls as they can be hazardous to my dog's health. Do you have any suggestions to control the weeds? I usually aerate and seed each fall and use a fertilizer in which I have confidence.

Hi -- Advising you on lawn weed control in Montgomery County is a bit complicated because of Montgomery County's new pesticide law which the Court of Special Appeals of Maryland recently ruled in favor of. They upheld the law restricting the use of pesticides (including herbicides) on private lawns and childcare facility grounds. So I am sending you to your county's lawn care page for information, https://www.montgomerycountymd.gov/lawns/law.html.

Also, read our page on lawn weed prevention and management,

And our information on organic lawn care, https://extension.umd.edu/hgic/topics/organic-lawn-care.

In the fall we recommend aeration, overseeding, and fertilization for good care of cool-season turfgrass lawns. Thickening the turfgrass and mowing high (at your mower's highest setting) will help with weed control. Please see our turfgrass maintenance calendar, https://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/lawn_pubs/HG11....
