When Does Bermuda Grass Go Dormant in South Carolina?

Your lawn is starting to look a little tired. Maybe there are patches turning tan. Maybe it just does not have that summer green anymore.

Here is what is actually happening — and what you should and should not do about it.

What Bermuda Grass Dormancy Looks Like

Bermuda grass is a warm-season grass that thrives in heat. When soil temperatures drop below about 50°F, it starts to shut down. The grass blades stop growing, lose their chlorophyll, and turn from green to a golden tan or straw color.

This is dormancy — not death. The roots stay alive underground, waiting for warmer temperatures to return.

When Does Bermuda Grass Go Dormant in Upstate SC?

In the Greenville, Spartanburg, and Anderson area, bermuda grass typically enters full dormancy in mid-October to early November. The exact timing depends on a few things.

Night temperatures consistently below 50°F. In the Upstate, this usually happens in late October. Some years it arrives earlier, some later.

Your yard's sun exposure. South-facing slopes and yards with full sun stay warm longer and hold green a week or two past shaded areas.

Drought stress heading into fall. A dry August and September can push early dormancy by a few weeks.

The transition is gradual. You will notice the lawn slowing down in late September — growth drops off, the color starts fading. By mid-October, most Upstate bermuda lawns are well into the dormancy process. By November, they are fully dormant.

Is My Bermuda Grass Dead or Just Dormant?

This is the most common question. Here is how to tell.

Signs of normal dormancy:

Uniform tan or straw color across the whole lawn
No new growth, but the turf is still firm underfoot
Green color returns to the edges and high-traffic spots first in spring

Signs something is actually wrong:

Patches of dead grass surrounded by green areas (not uniform)
Lawn that does not come back in spring where it should
Soft or mushy spots that smell bad

A dormant bermuda lawn looks rough but bounces back reliably in spring. A bermuda lawn with disease or root damage will have irregular dead patches that do not recover.

What to Do While Your Bermuda Is Dormant

Do:

Limit heavy foot traffic. Dormant turf is more fragile than growing turf.
Watch for large patch fungus in the first weeks of dormancy. The transition period is when this disease strikes. Signs are circular, discolored patches.
Make note of thin or bare spots for spring repair.

Do not:

Apply nitrogen fertilizer. Fertilizing dormant bermuda is wasted product at best and can feed weeds at worst.
Water heavily. Dormant bermuda needs very little — maybe once every three to four weeks in dry conditions.
Scalp the lawn in fall. Some homeowners cut bermuda very short in October thinking it helps. It does not. It removes the protective layer of dormant blades.

When Does Bermuda Grass Come Back in Spring?

In Upstate SC, bermuda grass green-up typically starts in early to mid-April, when soil temperatures climb back above 60°F. In a warm spring, some lawns start showing green as early as late March. After a cold or late spring, it can be mid-April before you see real growth.

Do not be alarmed if your lawn looks dead in February and March. That is completely normal for dormant bermuda.

What Happens to Your Trimly Robot Mower in Winter?

If you have a Trimly robotic mowing subscription, your mower is covered year-round. During dormancy, your Segway Navimow automatically goes into standby mode — it stops cutting when growth stops. Trimly Fleet Managers collect mowers for winter service: blade sharpening, firmware updates, and full inspection before spring reinstallation.

If you are on growing-season billing, your subscription pauses automatically for the off-season and resumes in spring. You only pay for the months your mower is active.

Spring installations and reactivations begin in March — reach out early if you want to be first on the schedule.

Frequently Asked Questions

When does bermuda grass go dormant in South Carolina?

Bermuda grass goes dormant in Upstate South Carolina when soil temperatures consistently fall below 50°F, typically in mid-October to early November in the Greenville, Spartanburg, and Anderson areas. The transition starts in late September as growth slows and color fades.

Why is my bermuda grass turning brown in September?

Bermuda grass begins its dormancy transition in late September in Upstate SC. Slowing growth and fading color are normal signs the grass is preparing for winter. If the browning is uniform across the lawn, it is almost certainly dormancy. Irregular dead patches in a ring or circle pattern may indicate large patch fungus.

Does bermuda grass come back after going dormant?

Yes. Dormant bermuda grass is alive underground. In Upstate SC, bermuda green-up begins in early to mid-April when soil temperatures exceed 60°F. The lawn will look dead through winter and early spring, then green up rapidly once temperatures warm.

Should I water bermuda grass during dormancy?

Dormant bermuda grass needs very little water — roughly once every three to four weeks during extended dry periods. Heavy irrigation during dormancy encourages weeds and can promote fungal disease. Let the lawn rest.
