Reviving a Lawn with Large Dead Patches After Scalping

A lawn that's green from a distance but brown underneath, especially after being scalped by a mower set too low, is crying for help. Bagging clippings for years has starved it of natural nutrients, and chemical treatments for chinch bugs may have further stressed it.

Hands-Off Recovery Plan

1. Stop mowing for a month—let the grass grow until it's above the mower's highest setting.
2. Mow high, no bagging. Use the highest setting and leave clippings. If your mower has a mulching plate or mode, use it; otherwise, consider a mulching mower.
3. Water consistently (rain or irrigation) to support regrowth.

This approach lets the grass rebuild root reserves and leaf area. The clippings return nitrogen and organic matter. Recovery takes weeks, but the lawn will come back stronger without chemicals.
