1. Wait for Warm Soil<\/h2>
Coulston, a homeowner and founder of Coulston Construction in Kansas City, Missouri, timed his raking, aerating, and overseeding with the natural greening of his lawn, a sure sign that the soil temp is ideal for repairs. <\/p>
“I\u2019ve learned from experience that doing it too early just leads to wasted seed and patchy results,” says Coulston.<\/p>
These tasks, along with warm soil, are a good mix for repairing winter damage. You need healthy grass tough enough to handle raking and aeration, and soil warm enough to germinate grass seed. <\/p>
For cool-season (northern) grasses<\/strong>, like Coulston’s tall fescue, that means soil temps above 50 F<\/strong> for several days running. For warm-season (southern) grasses, at least 60 F<\/strong>. The visual cue?\u00a0When you see green grass on most of your lawn\u2019s surface, you\u2019re good to go.\u00a0<\/p>
Paul Landis of ProTurf Landscape & Lawn Care in Maryland uses the last frost of spring as his guide. If your repairs include overseeding (and they often do), Landis says to wait \u201cuntil after the last frost date in your geographic zone\u201d to protect seedlings from low temperatures.<\/p>
Pro Tip:<\/strong> Wait for the soil to thaw and dry before starting repairs (you don\u2019t leave footprints). <\/p>
2. Remove Debris and Dead Material<\/h2>
Best post-winter grass treatment to start with? Cleaning: unglamorous, but so effective. Remove twigs and fallen branches. Use a flexible leaf rake to clear away leaves, dead grass, and thatch<\/a>. Let the sunlight reach the good grass hiding underneath. It\u2019s been waiting all winter.<\/p>
If there\u2019s no sign of disease, toss it all in your compost bin. Weeds poking through? Pull them now. The soil is soft, the roots are shallow, and they\u2019ll slide right out. <\/p>
Note: <\/strong>If the thatch layer is thicker than 1\/2 inch, raking won\u2019t suffice. You\u2019ll need to dethatch the lawn<\/a> with a dethatcher (no way around it).<\/p>
3. Assess and Identify Causes of Winter Damage<\/h2>
Before you do anything (treat, reseed, fertilize), walk your lawn and figure out what actually caused it to have dead grass after winter. Here are the top 3 causes that mess with winter lawns and the signs they leave behind:<\/p>
