Bare patches in GTA lawns are caused by salt damage, heavy traffic, grubs, and clay compaction. Step-by-step repair guide for seeding, sodding, and soil prep in Ontario.
Technically yes, but germination success will be very low — under 30% — without removing dead material, loosening the soil, and maintaining consistent moisture. Seed dumped on compacted or sealed soil sits on the surface, dries out, and either fails to germinate or germinates and dies within days when roots cannot penetrate the soil.
Recurring patches in the same location almost always indicate an unresolved structural issue: compaction, shade, poor drainage, salt accumulation, or recurring pet activity. Identify the pattern and address the root cause before repairing. A professional lawn assessment can identify recurring-patch causes quickly. Trim Gym offers free property consultations in the GTA.
The most effective prevention is a dense, well-fed lawn going into winter — thin or stressed grass is far more vulnerable to ice damage, salt, and snow mould than healthy turf. A fall fertility program, core aeration in September, overseeding thin areas before freeze-up, and reducing road salt application near lawn edges all reduce the severity of spring bare patches.
