“Oh the weather outside is frightful, but my lawn looks so delightful, so as there’s no grass to mow, let it snow, let it snow, let it snow…”
Waking up to find your garden in a ‘white out’ can be fun – thoughts turn to building snowmen, making snow angels, pelting loved ones (and maybe not so loved) with snowballs while watching little ones systematically mess up every single patch of untouched snow. As far as your lawn is concerned, snow generally causes little in the way of problems so there is no reason to worry when you wake to find it covered by a white blanket.
Snow isn’t as regular an occurrence as it was in the past few decades – southern parts of the UK have not received particularly long sustained periods of snow cover for a long time. Given that damage to our lawns from snow is very rare, we should still be aware of a fungal disease called Snow Mould.
Snow Mould can sometimes develop when the snow melts. It is most likely to form where a large amount of snow has gathered, such as the piles of snow dumped when clearing a drive. Snow Mould is basically the same as another lawn fungus called Fusarium Patch, a mycelium fungus that attacks the leaf and crown of lawn turf whilst the snow is melting. It can cause the grass to die back, it can turn white and often becomes matted. In some cases, lawns will recover during the spring as temperatures rise but often the grass is killed – this means dead patches may require re-turfing as the fungus can be so aggressive as to kill the roots of the grass plant.
