Is My Grass Dead or Just Dormant?
Before you tear up a brown lawn or dump money into it, find out whether it's actually dead or just dormant — a survival mode grass drops into during heat or drought. Most brown summer lawns are dormant and will recover; the fix is patience and water, not a reseed.
How to tell
- Dormant grass browns fairly evenly across an area and follows the heat and sun, not random patches.
- Tug a handful: dormant grass resists and the crowns at the soil line are firm and off-white.
- Truly dead turf pulls out in a loose handful, and the crowns are brown, dry, and crumbly.
- Dormant grass greens back up within a week or two of a deep soak or a cool spell; dead patches don't.
What to do
- Step 1
Do the tug test
Grab a handful of the browned grass and pull. If it holds firm and the base is white and firm, it's alive and dormant. If it lifts out easily with dry, brown crowns, that patch is dead and will need repair.
- Step 2
Water deeply, then wait
Give the lawn a deep, early-morning soak and watch for a week. Dormant grass perks up and re-greens once it gets water or the heat breaks; what stays brown after that is the part that actually needs renovating.
- Step 3
Repair the dead spots at the right time
Save real repairs for the right window, and match the method to your grass. Cool-season lawns (fescue, bluegrass, ryegrass) are reseeded in early fall, when cooling air and warm soil give new seed its best start. Warm-season lawns repair fastest during warm-weather growth — bermuda and zoysia from seed, sprigs, or sod, and St. Augustine only from sod, plugs, or sprigs (it can't be grown from seed). Repairing in the wrong season, or reseeding in summer heat, usually just wastes the effort.
Not sure this is the one?
Dead or dormant? is one of several causes that look alike from the porch. Answer a few quick questions in the free diagnosis tool and it checks your symptoms against all of them — and what to do about each — no signup required.
Diagnose my lawnPreventing it next season
Mow high, water deeply but infrequently, and avoid feeding cool-season grass in summer heat — a lawn that goes into summer strong rides out dormancy and bounces back instead of dying.
Frequently asked questions
- How long can grass stay dormant and still come back?
- Healthy turf can survive several weeks of dormancy. The longer the drought, the slower the recovery, so a light watering every couple of weeks during an extended dry spell keeps the crowns alive without breaking dormancy.
- Will watering bring a dormant lawn back to green?
- Usually yes — dormant grass re-greens within one to two weeks of consistent water or cooler weather. If a patch stays brown after that, it's likely dead and needs repair — reseeding for cool-season lawns in fall, or plugs, sprigs, or sod for warm-season grasses like St. Augustine that aren't repaired from seed.
