How does snow affect grass?

The affects of snow on grass

After a visit from ‘The beast from the east’, gardens all over the UK are currently under several inches (or feet, depending on where you are located) of snow. If you’re wondering how your lawn will be affected by a few inches of the white stuff, read on for top tips and advice from Essex turf grower, Paynes Turf.


Heavy bouts of snow can sometimes cause the onset of a fungal disease, commonly known as snow mould. The disease is caused by the action of snow thawing and then freezing, as this creates a layer of ice between the turf and subsequent layers of snow. Snow mould doesn’t become apparent until the snow melts, revealing patches of yellowing, dying turf which eventually turns brown, and leaves signs of a white fungal growth. So how can snow mould be prevented? To begin with, make sure that the lawn has adequate drainage; if water isn’t draining away quickly from the surface, aerate the lawn.

How to care for a snow covered lawn

It’s not only gardens that have been affected by the recent snowfall – our turf fields are also under several inches of snow. And when our fields are covered by snow we are unable to harvest, as the turf could become damaged.

In the same way, care should be taken in gardens when snow is covering the grass. Try not to walk on snow-covered grass whenever possible as the grass leaves could become damaged; the blades of frozen grass leaves could easily snap, which will allow frost to reach the cells in the leaves.

Don’t attempt to remove snow from your lawn with a garden spade as you could do far more damage than good. The action of scraping a spade over the grass is certain to damage the grass leaves, in the same way (if not worse) than walking on the lawn. It’s always best to simply wait until the snow melts naturally.
