Why Won’t Your Bare Spots Fill In?
You’ve tried everything and the grass still won’t grow. We’ll find out what’s actually blocking it and fix the problem for good.
Symptom overview
What This Looks Like
Bare spots that refuse to fill in despite your best efforts usually have an underlying issue preventing grass from establishing. In Middle Georgia, the problem is almost always below the surface.
Possible causes
What Could Be Causing This
Severe Soil Compaction
Heavy foot traffic, parked vehicles, or construction equipment crush Middle Georgia’s clay soil into a hard layer that grass roots can’t penetrate. These areas stay bare because nothing can establish in concrete-like soil.
Buried Debris or Shallow Rock
Rocks, concrete rubble, or construction waste buried under a thin topsoil layer prevent roots from growing deeper than an inch or two. The grass dies as soon as temperatures stress it because there’s no root system to support it.
Heavy Shade
Areas under dense tree canopy may get too little sunlight for any warm-season grass to survive. Even shade-tolerant St. Augustine needs 4+ hours of filtered light. If you keep planting and it keeps dying, shade may be the limiting factor.
Pre-Emergent Herbicide Barrier
Pre-emergent herbicides create a chemical barrier in the top layer of soil that prevents seed germination. If you’ve applied pre-emergent and then tried to seed or even establish plugs, the herbicide can prevent new grass from rooting for months.
Dog Traffic Paths
Dogs running the same path along a fence line or between doors wear the grass down to bare dirt. The combination of traffic compaction and urine makes these spots nearly impossible to regrow without changing the dog’s behavior.
Diagnose it
Narrow Down the Cause
Have you tried planting grass in these spots before and it died?
Repeated failure to establish means the soil conditions won’t support grass. Dig down 6–12 inches to check for rocks, debris, or concrete-hard clay.
Before replanting, address any visible drainage, shade, or compaction issues first. One attempt with the right prep is better than multiple failed attempts.
Are the bare spots along a fence line or between the house and yard?
These are likely pet traffic paths or high-traffic walkways. The solution often involves redirecting traffic or accepting these areas need hardscape (stepping stones, mulch) instead of grass.
Random bare spots in the middle of the yard point to subsurface issues — buried debris, compaction, or drainage.
Did you apply pre-emergent herbicide in the last 3–4 months?
The pre-emergent barrier is likely preventing new grass from establishing. Wait until the product breaks down (check the label for residual time) before attempting to resod or plug.
Pre-emergent isn’t blocking growth. The issue is physical — soil quality, compaction, or shade.

When This Is Most Common
The best window to repair bare spots in Middle Georgia is May through July, when warm-season grasses are growing aggressively and sod establishes quickly. Avoid patching in winter (dormancy) or late fall (not enough growing time before dormancy).
Common questions
Frequently Asked Questions
What’s the best way to fill in bare spots in a warm-season lawn?
For bermuda and zoysia, sod plugs or full sod pieces work best because these grasses spread laterally. Fix the underlying soil issue first (aerate, add topsoil if needed), then install sod during active growing season. Keep it watered consistently for 2–3 weeks.
Can I just throw seed on bare spots?
Most warm-season grasses used in Middle Georgia (bermuda hybrids, zoysia, centipede, St. Augustine) don’t establish well from seed. Sod or plugs are more reliable. Common bermuda can be seeded, but it’s a coarser variety than what’s typically in established lawns.
Should I use topsoil to fill in bare spots?
If the bare spot is lower than the surrounding lawn, yes — add topsoil to level it before sodding. But topsoil alone won’t fix compaction or buried debris. Address the root cause first, then level and sod.
