Do you see patches of straw-colored sections in your yard? While the initial diagnosis may be your turf isn’t getting enough water, there’s a common turf disease making the rounds in Colorado.
Ascochyta leaf blight is a common problem on Kentucky bluegrass lawns according to a report by Colorado State University. The Ascochyta fungus “likely survives as spores” on clippings or dead leaves. That’s why the first line of defense against this problem is proper turf management.
Keeping lawns and plants watered is an important part of proper management. Associated Landscape Contractors of Colorado recently released reasons why mulch is good for your landscape, including how the organic materials decrease evaporation rates from your soil by as much as 35 percent.
Mulch insulates plants, suppresses weed growth and provides an even appearance. It comes in a variety of colors and can even be crafted from your local pruning debris. However, you shouldn’t increase your trips out with the lawnmower to create your next batch of mulch.
Frequent mowing and dull mower blades can make the Ascochyta even worse, so it’s important to keep a lawnmower’s blades clean with bleach, especially if it’s being used on multiple properties.
Keys to solving this problem are:
Uniform soil moisture – With properly placed mulch and a well-monitored water irrigation system, drought stress won’t be a concern.
Have patience – Ascochyta blight isn’t a crown or root disease. Therefore while it looks bad on the surface, it’s just that – on the surface. With enough time and normal management practices, your lawn will recover, and new leaves will emerge.
