I have had several clients ask about the damage that our recent snowfall is doing to their land. I am definitely not the expert on this, but found a really helpful answer on Turf King-Hamilton- Lawn Care.
Some plants will benefit from a little extra snow during the winter. Snow around the rose bushes will provide some insulation from the sap-chilling deep freeze of this past week. Bitterly cold temperatures for prolonged periods of time will result in more roses biting the dust this winter.
On the lawn, a thick layer of snow will not harm it, provided that there aren’t leaves left on the surface. The snow and leaves combine to prevent air from the foliage. This is likely to lead to accumulation of water under the leaves which in turn will lead to putrefaction. If the grass is cut short in the fall, the lawn is less likely to get diseased by the longer leaf blades being smothered. The last mowing should always be a little shorter. (the problem I’ve had is that autumn doesn’t seem to know when to quit, and I end up with 2 or 3 last cuts. Don’t cut the lawn too short of course, as this makes it more susceptible to frost damage if there is little snow.
Grass that has been cut too short, on the other hand, is susceptible to frost damage.
If you walk on the lawn regularly during the winter, it is also advisable to remove the snow from these paths. Snow that is hard packed by foot prints on the lawn could lead to damage to the grass plants. (it could also lead you down a garden path)
I would love additional input on this from anyone with first-hand experience. Unfortunately my lawn probably won’t even notice the difference!
