Cold, wet weather can cause fungal diseases in your lawn. This spring has been extraordinarily cold and damp in northern Maryland, so be sure to keep an eye out for fungi. While we can’t predict the types of fungus that will prevail, nor can we control the weather, we simply have to watch and try to make sure the grass and soil have proper care and nutrients. One of the common diseases that appears in this type of weather is Red Thread disease. It’s easily identifiable by its red or pink color. Unfortunately, by the time it appears, it’s already too late. It has already affected the grass blade and become a patch. To make matters worse, it can be spread by windy conditions to other parts of your lawn.
Once you’ve identified Red Thread, you simply have to wait it out and let the infection run its course. One of the causes of Red Thread is low nitrogen levels in the soil, so you should be sure the soil is healthy. Any fungus on the lawn is an indication that something isn’t being done correctly. You can get a better idea of what might be causing it by consulting a lawn care professional. You can also follow a few simple steps when caring for your lawn, like not overwatering, using a sharp lawn mower blade and not cutting the grass too short. Overly wet grass and very short grass can be an ideal environment for fungus or bacteria. Talk to your lawn care professional about fungus prevention and balanced soil nutrients. They can offer good insight and services so that you won’t see that red thread running through your green grass.
