Lawn Diseases in the Winter and Spring Can Wreak Havoc on Your Lawn
- February 10, 2020
As winter ends and spring begins, our lawns become vulnerable to a number of lawn diseases. Wet weather and cool temperatures make the perfect environment for several turf-damaging diseases, making late winter and early spring an important time to stay vigilant. A lawn disease in the spring is a bad start to the year and sets your lawn back, restricting healthy growth and weakening your lawn. Here are a few of the common lawn diseases that may be affecting your lawn this winter and spring.
Of the two types of snow mold, gray snow mold is the less destructive one. Gray snow mold forms under the snow, in matted, wet grass. This fungus shows up in the yard as 6 – 12 circular patches of straw-colored grass. The edges of these patches are bordered by gray mycelium. Typically, the only part of your grass that is damaged by gray snow mold is the leaf blade. After it clears up, the grass grows back.
Pink snow mold is the other type of snow mold. Trust us, you don’t want to find pink snow mold in your lawn. Like gray snow mold, pink snow mold forms in matted grass during consistently wet and cold conditions. It forms under the snow and reveals itself as the snow begins to melt. However, there doesn’t need to be snow for pink snow mold to form. All this fungus needs is consistent moisture and cool temperatures. You can spot pink snow mold by watching for 1 – 8 inch patches of copper or reddish-brown colored grass. Look for the telltale pink border of mycelium around the edge of the patches. Unlike gray snow mold, pink snow mold attacks the roots and crown of your grass, often resulting in plant death.
Large patch is another lawn disease that you don’t want to find this spring. This lawn disease specifically attacks warm-season grasses like zoysiagrass, centipedegrass, and St. Augustine grass. Large patch is identified by the large patches of brown, thinning grass. These patches can be anywhere between 3 – 25 feet in diameter.
Large patch typically presents itself between March – June when temperatures reach 55 degrees or more at night. Too much moisture and heavy dew also play a role in the development and spread of large patch.
Brown patch is very similar to large patch, except it is a little smaller and affects all grass types. This is one of the easier lawn diseases to identify because it is exactly as its name suggests. Watch from brown patches of dry, thinning grass. Brown patch can be persistent and will weaken your turf. As your lawn’s immune system is weakened by brown patch, it becomes more vulnerable to problems like lawn-damaging pests, invasive weeds, and more lawn diseases.
Brown patch usually presents itself in the early to mid-spring. Too much moisture, not enough drainage, cool nights, and heavy dew all play a role in the development of brown patch.
One of the more interesting lawn diseases affecting our Tennessee lawns in the spring is fairy ring. Fairy ring shows up in the lawn as large circles of dark green or brown grass. These circles are surrounded by a ring of darker grass or mushrooms, making this a strange-looking lawn disease. Fairy ring may look interesting, but it’s incredibly damaging to your lawn. The fungus makes the affected area hydrophobic. This means the soil and grass repel water. Over time, the grass will wither and die from dehydration.
Fairy ring can form in the lawn at any time of the year but is more common during the wet spring. Be on the lookout after an extended period of really wet weather.
