How To Get Rid Of Black Mold On A Lawn

When black mold appears seemly out of nowhere, leaving patches of black slime on the lawn, grabbing the nearest fungicide is tempting. But for this problem, chemicals rarely work. Though unsightly, black mold is relatively benign and not difficult to treat.

Use plain water to get rid of the unsightly black patches quickly and easily. Set a hose nozzle to its strongest setting and spray the slimy black mold directly. The water dislodges the mold spores. Washing off the mold works best during dry weather or a few days before a period of dry weather. Once dislodged, the mold spores are less likely to hold up when the lawn dries out.

In wet or dry weather, use a lawn rake to get rid of black mold on the lawn. Rake the affected areas lightly using a flicking motion to break up the mold colony without damaging the lawn. After raking mold-infected areas, clean your rake and any other tools you used in a solution of 1 part standard bleach to 9 parts water. Either wash the rake with the solution, or dip it in a bucket with the water and bleach solution.

A lawn mower can minimize the appearance and damage of black mold on the lawn. In spring and fall, mow the lawn 2 1/2 to 3 inches tall and for summer set the mower to 4 inches tall, as you normally would. After mowing an area of the lawn affected by black mold, rake up the clippings and get rid of them. You can use the rest of the lawn clippings as mulch but make sure you don't get the black mold into the mix.

If you're short on time, just let it go. As it's most likely to show up during humid weather during the year, both in cool winter climates and wet spring and fall times, the mold will usually disappear when the weather dries out. If a shaded area succumbs continuously to black mold problems, consider removing the lawn and installing a shade garden instead.
