FOUR WINTER LAWN PROBLEMS
Frosty footprints
When grass blades are frozen they can’t absorb impact, the cells shatter when walked on, leaving dead brown patches.
Fusarium patch
This fungus appears in mild, wet conditions and often occurs after a covering of snow thaws out.
Red thread
Red thread, a fungus, appears in wet conditions, causing dead patches of turf, which usually do recover.
Worm casts
Worms can leave little mounds of soil on the lawn surface; remove the casts by brushing off with a stiff broom.
