Snow mould
When: April (revealed at snow melt)
Quebec’s heavy, reliable snow cover makes snow mould one of the most common spring issues. Aggressive raking is essential. Matted grey (Typhula) or pink (Fusarium) patches appear as snow melts. Most recover with raking and air circulation alone.
Road salt damage
When: May (visible after melt)
Brown, dead strips along driveways and walkways from winter salt accumulation. Flush affected areas heavily with water in early spring before grass begins growing. Apply gypsum to help displace sodium in soil. Use calcium chloride alternatives near lawns.
White grubs
When: August–September
European Chafer and Japanese Beetle grubs are significant pests in Montreal and surrounding areas. Brown patches that lift like carpet, skunks digging at night. Apply beneficial nematodes in August when soil is moist and warm.
