Bare spots in lawn: causes and fixes

A bare spot in a lawn is not a condition -- it's a symptom. Reseeding over a bare spot without identifying and correcting the cause produces the same bare spot a year later. The work order is: identify cause, fix cause, then.

1. High-traffic areas

Appearance: Worn paths, often following predictable routes (between doors, along fence lines, near play equipment). The grass is absent or severely thinned, and the soil is typically compacted and hard.

Why it happens: Per Penn State Extension, repeated foot traffic compacts soil and directly damages grass crowns, particularly on cool-season grasses with lower traffic tolerance than bermuda grass or zoysia.

Fix:

• If traffic cannot be redirected: install pavers, stepping stones, or a gravel path. Grass cannot compete with daily foot traffic on the same line.
• If traffic can be managed: core aerate, overseed with a high-endophyte perennial ryegrass (highest traffic tolerance among cool-season grasses), and restrict use for 6—8 weeks.
• Perennial ryegrass and tall fescue tolerate traffic better than Kentucky bluegrass or fine fescue. Per NC State TurfFiles, selecting a traffic-tolerant species for high-use areas reduces recurrence.
