Starting earlier reduces that conflict. If seed germinates and begins rooting before heavy leaf drop, the lawn has a better chance of surviving routine cleanup. Light leaf removal still matters, but the young grass is not as vulnerable as freshly sprouted seedlings.

During cold months, the ground often freezes, making water unavailable to grass roots. At the same time, dry, cold winds pull moisture from the grass blades. Without enough moisture, grass blades dry out and die, leaving brown patches across your lawn.
