Winterkill – How to repair the damage!

Cold weather lawn damage is a common problem for homeowners in colder climates. Winterkill can be visible in your lawn anywhere from small, isolated areas, all the way up to full-scale destruction. This unsightly and often unpreventable blemishing of your property can be brought on or worsened by any number of factors including ice, snow, snow mold and compacted soil.

Mild winters with many rapid thaws and re-freezes are particularly likely to leave your lawn with, at least some, winter damage, especially if there is insufficient insulation from snow. These types of winter can cause plant stress and irreversible damage to individual plants through crown hydration. That’s when your grass, thinking that it’s Spring, begins to take on water only to have it freeze again damaging its plant cells which usually will cause the plant to die.


While not all winter damage is controllable, fear not! All winterkill is repairable!

How to repair winterkill:

Step 1: De-thatch your lawn

Thatch is a layer of dead and living grass, leaves and other organic materials all mixed together. When the snow has melted and risk of frost is gone, rake away or use a de-thatcher to remove the layer of thatch. This will make it easier to treat your lawn and reach the roots and soil for improved treatment.


Step 2: Reinforce or replace your grass
