Everyone enjoys what seems to be the annual January thaw, but melting snowdrifts often reveal an ugly mess underneath. Snow mould, what usually looks like circular or irregular straw-colored patches on your lawn is a common disease. Grass that is left long and matted in the fall creates a favorable home for the disease. Areas that are prone to snow drifts or where snow is pilled up through out the winter can also increase the disease chances of survival. Avoid applying nitrogen to your lawn during October, the lush green grass blades that nitrogen promotes, can also lead to the development of snow mould. So what do you do if your lawn shows signs of snow mould? In the spring you want to encourage drying of the effected area, best way to do that is to rake the matted areas, then fertilize lightly to help speed up the recovery.
Hi
Another tip I found useful was to encourage grass growth by mowing the lawn pretty closely quite late on the year – or (if it’s too late in the day for that) to mow again first thing in the spring. New growth seems to help a lot in ridding your turf of snow mould.
