How to Treat a Frostbitten Lawn

You can't prevent the winter chill, or the havoc it plays on your manicured and cared-for lawn. During cold snaps, your lawn, like other plants and animals, may suffer from a case of frostbite. The best cure is, of course, prevention: Aerate and seed your lawn before the first frost and use commercially available grass care products designed to protect lawns from freezing. However, once the damage is done, time and care will revitalize your traumatized grass.

Instructions

- 1
  Look for signs of frostbite versus other lawn diseases or conditions. Frostbitten grass will have brown, dry blades with roots that are green and alive.
- 2
  Leave the brown blades alone until the danger of another frost has passed. The already-frostbitten grass helps protect the rest of the grass from frostbite.
- 3
  Mow lightly and weed gently after the last frost. Reseed as necessary, but avoid immediately fertilizing your lawn. The grass is actually quite delicate, and adding fertilizer before it completes at least one new cycle of growth further damages the grass.
- 4
  Water lawn on the same schedule used the prior spring.
- 5
  Continue gentle care, light mowing and usual watering, until grass has started to green in most places. By this time, it can tolerate a fertilizer application.
