Brown spots in your lawn may signal that Grubs are present and feasting on grass roots. To determine if Grubs are the culprit, pull on the brown grass. If it pulls free with no roots, carefully dig and lift a section to check for c-shaped Grubs. If you do have grubs it's worth contacting Turf King to control Grubs in Muskoka and Orillia, if you do not in spring they'll continue their underground lawn destruction! www.TurfKingMuskoka.com
