When you have humid, wet, overnight weather in the upper 60’s and low 70’s what does that create? It creates all three required sides of the Disease Triangle for fungi, and lately, that’s exactly what Kansas City has been having.
Brown Spots In The Grass
Brown spots in your lawn can be caused by a number of different things. Right now diseases can be a major culprit. The late afternoon and evening rains are making for damp humid conditions throughout the night. Add to that the temps are warming up and we have all the ingredients for a disease outbreak.
Quick Tip To Identify if its a Fungus
If you start seeing areas of the lawn with a brownish appearance, take a closer look at the individual leaves of the grass plants. Do they have brown areas? Are they in the middle of the leaf blade or at the top or at the bottom? If you have spots in the middle or bottom of the leaf blade then it is likely a disease. If the brown is on the end of the leaf it is more likely environmental or mechanical injury (i.e. drought stress or dull mower blades).
What To Do If You Have A Fungus In The Lawn
Not all diseases are fatal to the grass. Your best bet now is to contact your Lawn Coach for an accurate identification of which fungus it is and then he can inform you of your options. In some cases the best bet may be to just let it grow out. But if you have had a history of problems you may need to treat. Fungicides are better preventatives than they are curatives. What that means is that the damage that is done will be there but now we are trying to keep it from spreading throughout the entire lawn. In the future you may want to time treatments proactively rather than as a rescue. Some Heritage customers who have a history of fungus were provided with their first preventative treatment last week.
