Atlanta Topdressing Schedule for Bermuda and Zoysia Lawns
A bumpy lawn feels like walking on a lumpy mattress. Your mower scalps the high spots, the low spots stay wet, and weeds seem to pick the worst places to thrive. That's why Atlanta lawn topdressing matters, especially on warm-season lawns growing in heavy red clay.
Topdressing is simple in concept: spread a thin layer of sand, soil, or compost over turf. Done at the right time, it smooths the surface, protects roots, and helps turf fill in thicker. Done at the wrong time, it can smother grass and waste a weekend.
The big rule for Atlanta lawns: topdress only during active growth , when Bermuda and Zoysia can grow up through the material.
The right Atlanta topdressing windows (and a simple schedule you can follow)
In Metro Atlanta, Bermuda and Zoysia usually wake up in spring, then hit their stride in late spring through summer. For timing, don't chase the first warm afternoon. Watch for steady growth and warmer soil. The University of Georgia's calendar also warns against early spring nitrogen until the 4-inch soil depth is consistently warm and rising, which lines up with when turf is truly ready for heavier work like leveling and topdressing (see the UGA Bermudagrass lawn calendar PDF ).
Use this table as a practical Atlanta topdressing schedule. It's written for typical home lawns using rotary mowers.
One quick note before the table: if your lawn is still "half green," wait. Topdressing too early is like putting a blanket on someone who hasn't woken up yet.
| Grass type | March | April | May | June | July | August | September |
|---|---|---|---|---|---|---|---|
| Bermuda | Avoid, turf is transitioning | Light cleanup only if growing | Best window begins, start light leveling | Prime window, 1st or 2nd light topdress | Prime window, touch-ups ok | Light only, watch heat stress | Last call for light topdress if still growing |
| Zoysia | Avoid, too slow to recover | Avoid heavy work, wait for steady growth | Possible, only if fully active | Best window, one light application | Optional spot leveling only | Usually skip, heat stress risk | Usually skip, recovery slows |
Takeaway: Bermuda can handle more frequent light topdressing. Zoysia usually looks best with fewer, lighter applications.
If you remember one thing, make it this: topdress when the lawn is growing fast enough to "eat" the material. Dormant grass can't.
What to topdress with in Atlanta red clay (and how deep to go)
Atlanta soil is often dense clay. That creates two common problems: poor drainage in low spots and hard, compacted ground on high spots. Topdressing helps, but your material choice matters.
Good options for Bermuda and Zoysia topdressing
- Washed, screened sand : Best for leveling because it doesn't break down. Many homeowners use a washed, coarse sand (often sold as concrete sand). Avoid very fine sand with lots of powdery fines.
- Sand plus compost (light blend) : Helps if your soil is tight and you want more organic matter. Keep compost screened so it spreads evenly.
- Screened topsoil : Can work, but it's harder to spread evenly and can clump after heavy rains.
For DIY results, screening is the difference between "golf-course smooth" and "why is my yard full of pebbles?" Aim for screened material that flows through a shovel easily. If you use compost, screen it to about 1/4-inch so it disappears into the canopy instead of sitting in chunks.
Depth guidance that won't smother your turf
- Typical topdressing depth: 1/8 to 1/4 inch
- Aggressive leveling: up to about 1/2 inch total , but only by doing it in multiple passes (for example, 1/4 inch now, then another 1/4 inch after the lawn grows through)
If you can't see grass tips after spreading, you went too heavy. Bermuda may fight through better than Zoysia, but either one can thin out if buried.

Step-by-step: how to topdress Bermuda or Zoysia the DIY way
Topdressing isn't complicated, but order matters. Think of it like painting a wall. Prep work decides whether the finish looks smooth.
1) Mow low, but don't punish Zoysia
Start with a short mow so material falls into the canopy instead of sitting on top.
- Bermuda: a spring scalp can make sense once freeze risk is low and growth is steady. Bagging helps.
- Zoysia: keep it more conservative. It's slower to recover and scalps easily on uneven ground.

2) Fix thatch and compaction before leveling
If the lawn feels spongy, thatch may block topdressing from settling. If the soil is hard as a brick, compaction will limit recovery.
- Dethatch or power rake only if thatch is truly a problem.
- Core aerate if water puddles or runoff is common, especially on clay slopes.
3) Spread the material evenly
Use wheelbarrows and a shovel, then drop small piles around the area. After that, spread with:
- a landscape rake,
- a leveling rake,
- or a drag mat for larger areas.
Work in small sections. It's easier to fix a thin layer than a buried lawn.
4) Brush or drag it into the canopy
Drag until you see grass blades poking through. On Zoysia, stop sooner. Leaving a heavy layer on top is where Zoysia gets stressed.
5) Water lightly, then return to normal irrigation
Right after topdressing, a light watering helps settle sand and reduce dry pockets. Overwatering can wash material downhill, especially during Atlanta thunderstorms.
Keep your topdressing off sidewalks and driveways. Sweep it up so it doesn't wash into storm drains during the next rain.
6) Mow again once the lawn grows through
Resume mowing when the grass has grown above the topdressing. Keep the blade sharp. A dull blade tears leaf tips and makes the lawn look brown.
Atlanta-specific problems: drainage, shade, and weeds (and when to hire a pro)
Atlanta lawns rarely fail for one reason. A few local issues tend to stack together.
Heavy clay and drainage: Low spots stay wet, then thin out. Topdressing can help, but it won't fix standing water caused by grading. If water sits for hours after rain, consider drainage work or re-grading before you keep adding material.
Shade under trees: Bermuda needs sun, and Zoysia tolerates some shade but still thins in deep shade. Don't topdress heavy in shady areas hoping it'll "fix" thin turf. In those spots, reduce expectations, prune for light, or rethink the planting.
Weed pressure: Bare spots invite crabgrass and nutsedge. After leveling, keep your weed plan tight so turf can reclaim space.

When it's smart to bring in a pro
DIY works great for light smoothing. Hire help when:
- you have major leveling needs across most of the yard,
- low spots are deeper than 1 inch,
- drainage problems require grading, not just topdressing,
- you need material delivered and moved fast (sand is heavy, and it adds up).
Conclusion
A good Atlanta lawn topdressing plan is mostly about timing and restraint. Hit late spring through summer when Bermuda and Zoysia are growing hard, keep layers in the 1/8 to 1/4 inch range, and go lighter on Zoysia. If you spread too deep, the lawn can't breathe, and recovery slows. When you stay patient and consistent, you'll get a smoother yard that mows cleaner and fights weeds better all season.
