As temperatures drop and lawns lose their lush green color, many homeowners start wondering: does grass grow in winter? The short answer is: it depends. Both the type of grass you have and your local climate play a major role in how your lawn behaves through the colder months.
If you’re in South Carolina or the Southeastern U.S., here’s what you need to know about what your lawn is doing during winter — and how to take care of it.
When Does Grass Stop Growing in Winter?
Grass doesn’t grow year-round. Most grasses enter a dormant or slow-growth phase when temperatures consistently fall below 50–55°F. In South Carolina, this typically happens in late November or early December, depending on the year.
Once this threshold is reached, your lawn won’t need frequent mowing or watering — but it does still need basic maintenance to stay healthy until spring.
What Temperature Stops Grass Growth?
Grass growth largely hinges on soil temperature rather than just air temperature. For most lawns:
- Warm-season grasses (like Bermuda, Zoysia, or Centipede) stop growing when soil temps drop below 55°F.
- Cool-season grasses (like Fescue or Ryegrass) may continue slow growth into the low 40s before becoming dormant.
If you’re not sure what type of grass you have, now’s a great time to find out. Remember, how you care for it in winter will differ.
Can You Plant Grass Seed in Winter?
Yes, but it depends on your goals. While traditional seeding isn’t ideal in winter due to cold soil and poor germination rates, dormant seeding is a method that works in colder climates.
Dormant seeding involves planting cool-season grass seed in late fall or early winter, after growth has stopped. The seed lies dormant through winter and begins to germinate once soil temps warm up in early spring.
In South Carolina, this method is best used for cool-season grasses, particularly in shaded areas or lawns with bare spots that don’t recover on their own.
Do You Need to Fertilize Grass in Cold Weather?
In most cases, winter is not the time for standard fertilizer applications. However, applying a winterizing fertilizer in late fall (before your grass goes fully dormant) can help strengthen roots and prepare your lawn for spring growth.
These fertilizers are typically higher in potassium, which boosts cold hardiness. If your grass has already gone dormant, wait until early spring to apply any products.
Not sure if your lawn needs winter fertilization? WP Law can recommend a lawn care plan based on your grass type, soil, and property needs.
Keep Your Lawn Healthy Through the Cold Months
Grass may slow down or stop growing in winter, but your lawn still benefits from the right care and attention. Knowing when to mow, whether to seed, and how to fertilize sets the stage for healthy spring growth.
