When The Cold Brings Mold©
The weather is still cold and damp and most of us are not thinking of our lawns. But this time of year you still need to pay attention to what is going on with your lawn, especially if you've had lots of snow.
Pink snow mold can form with or without snow cover and often manifests itself as pinkish matted areas on the lawn. This disease appears when temperatures are in the 40 to 50 degree range and weather has been damp. Most lawns are not severely damaged by pink snow mold, but if it developes during the fall, it can damage the lawn more severely as it continues into the spring. After the weather warms up, pink snow mold spores will lie dormant in soil, grass plants, or thatch, and will once again germinate when temperatures cool down. Control of this disease is not to difficult and prevention is always best. Keep your lawn cut well into the fall so that the grass does not flop over and mat. Also, avoid piling snow very deeply, as this encourages the development of the disease. If the disease is severe, the application of a fungicide will help control it. Gray snow mold is noticed after the snow melts in the spring and it appears most often where snow has been piled deeply. The grass blades will have a white or bleached appearance and often mat together. The bleached areas of grass can range from a few inches to several feet across. Prevention and control are the same as for pink snow mold. Here are a few websites to visit which show good photographs and additional information about these diseases: http://www.agric.gov.ab.ca/pests/disease...
