Snow Mold Alert : Twin Cites I recently noticed a fair amount of snow molds showing up in area lawns before the latest snowfall. Please read article to minimize your damage. Snow molds are fungal diseases that flourish under snow, especially when the ground is not thoroughly frozen before the first snow and when snow cover is present for extended periods. Snow molds are named for the webby material or mycelium that grows over circular patches of matted grass. If you see this in your yard the best thing to do is rake the matted areas with a flexible poly rake so the grass stands up allowing air to circulate around the plant to dry out. Do not irrigate whenever molds are present. The following steps can be taken to minimize damage in future years: 1. Avoid excessive applications of nitrogen fertilizer in the fall. 2. Continue to mow the lawn at the recommended height until it is no longer actively growing. The taller the grass, the more likely it will mat down and encourage snow mold development. 3. Rake up leaves in the fall. 4. Manage the thatch layer with aeration to avoid accumulations of more than ½ inch. 5. Spread out large snow piles to encourage rapid melting. Use snow fencing to minimize snow accumulation in problem spots
