Looking Out for Common Diseases on Your Lawn
This article was published originally on 6/11/1999
Just a quick reminder on common lawn diseases that you might encounter as we head into the summer season. For diseases with an irregular pattern, be on the lookout for powdery mildew, rust, and leaf spot or melting out. Here are a few quick visual diagnostic tips for these diseases:
If affected areas are circular in pattern, watch out for dollar spot, fairy ring, necrotic ring spot, and summer patch.
Preventing fungal lawn diseases is a lot easier than trying to cure them. This can be done by planting resistant varieties; aerating to improve root growth, soil drainage and air exchange; dethatching, fertilizing properly, and watering deeply but infrequently especially during dry periods of summer and fall. Chemical sprays may be helpful but are only effective when applied before the disease becomes severe, and may not be necessary when proper cultural practices are followed.
