Spring lawn care in Columbia doesn’t have to be overwhelming. LawnStarter can be your reliable partner for tackling the heavy lifting, but there are simple steps you can handle yourself to get your grass looking its best.
Start by cleaning up winter debris and testing your soil, then repair bare patches, mow at the right height, water wisely, fertilize at the right time, apply pre-emergent to prevent weeds, and aerate or dethatch if needed. Follow these steps, and your lawn will bounce back ready for Columbia’s long, hot summer.
1. Clean Up Winter Debris
Columbia winters may be mild, but leaves, pine straw, and small sticks still pile up. If you leave them, grass struggles to breathe, sunlight can’t reach the soil, and wet spots invite disease. Clay-heavy areas can stay soggy longer, which encourages mold and fungus if debris is left on top.
What to do:
- Walk your yard and remove sticks, leaves, and pine straw.
- Rake lightly over flattened areas to lift the grass without tearing it up.
- Pay extra attention to shady or damp spots where debris sits.
- Keep an eye on areas near trees; pine needles can acidify soil and affect pH if left too long.
When to do it: Late February to mid-March, before warm-season grasses (Columbia’s best grass type) like Bermuda, Zoysia, or Centipede start greening.
Once debris is gone, you’ll spot bare patches or areas that may need repair. This also gives your soil a chance to dry out slightly before spring rains.
2. Test Your Soil
Columbia’s soil is a clay-sand mix, sometimes acidic, sometimes slightly alkaline in pockets. Testing is crucial because it affects fertilization, lime applications, and which grass type will thrive.
What to do:
- Collect 5 to 10 small soil samples from different areas of your lawn and mix them together.
- Send a sample to Clemson University’s Agricultural Service Laboratory for analysis.
- You’ll get a report with your soil’s pH, nutrient levels, and recommendations for fertilizer, lime, or other amendments.
When to do it: March to early April, before fertilizing or overseeding.
Tip: Centipedegrass prefers slightly acidic soil (pH just below 7), while Bermuda and Zoysia handle a broader range (5.8 to 7). Test now, and you can adjust with lime or sulfur to set your lawn up for summer success.
3. Repair or Reseed Bare Patches
Winter foot traffic, shade, or soggy clay soil often leaves bald spots. Columbia homeowners often notice patches near walkways, driveways, and shady backyard corners.
What to do:
- Loosen the top inch of soil.
- For Bermuda or Zoysia: use plugs or sod pieces.
- For Centipede: add compost to help roots establish.
- Water lightly, just enough to keep the soil moist.
When to do it: Mid to late April, once the soil warms (approximately 65°F) but before the summer heat.
Tip: Shade matters. Bermuda struggles in shade; Zoysia tolerates partial shade; and Centipede can tolerate light shade but not heavy traffic. Sun-loving areas should be planted with Bermuda or Zoysia for the best results.
4. Mow High (and At the Right Time)
Spring growth in Columbia is delicate. Cut too early or too low, and you’ll stress the grass, invite weeds, or dig ruts in soft clay soil.
Recommended heights:
- Bermuda: 1 to 2 inches
- Zoysia: 1 to 2.5 inches
- Centipede: 1.5 to 2 inches
- Tall fescue: 3 to 3.5 inches
What to do:
- Wait until the lawn is fully green.
- Sharpen blades because dull ones tear grass.
- Don’t remove more than 1/3 of blade height.
- Only mow when the soil is firm and dry.
When to do it: Late April, sometimes mid-April if the ground dries and warms early.
Remember: First cuts are more “wake-up trims” than heavy haircuts. Taller grass shades the soil, reduces weeds, and builds strong roots, especially important in hot, humid Columbia summers.
5. Water Wisely
Spring rain in Columbia is generous. Don’t fall into the trap of overwatering. Shallow roots today mean trouble tomorrow.
What to do:
- Skip sprinklers until the soil actually shows signs of dryness 2 to 3 inches down.
- When watering, soak deep enough to reach about 6 inches of soil.
- Morning is best. Water before the sun evaporation steals it.
When to do it: Most lawns can hold off until late April/May, depending on rainfall.
Tip: If your lawn still feels soft or muddy, wait. Let the grass tell you when it’s thirsty. Bermuda and Zoysia are drought-tolerant once established; Centipede prefers consistent moisture but dislikes standing water.
6. Apply Pre-Emergent Herbicide
Crabgrass and other weeds love the spring in Columbia. Pre-emergent is your best friend, but timing is key.
What to do:
- Apply a crabgrass pre-emergent labeled for your grass type.
- Lightly water it in or rely on rainfall.
- Avoid disturbing the soil afterward; no heavy raking, aeration, or dethatching.
When to do it: Mid-March, when the soil is around 50 to 55°F, before warm-season grass starts greening. The second application is optional, 8 to 10 weeks later, depending on weed pressure.
Tip: Apply near walkways, driveways, and garden edges. Weeds often start there first.

7. Fertilize (But Wait Until the Grass Is Ready)
Warm-season grasses hate early fertilizer. Early feeding can make blades grow fast, but roots lag—a disaster in Columbia’s summer heat.
What to do:
- Follow soil test results.
- Use slow-release nitrogen.
- Spread evenly, avoid clumps, and water lightly.
When to do it: Early to mid-May, once your lawn is fully green. Centipedegrass likes to wait even longer (closer to late May). This timing lets grass grow strong roots before heat and humidity hit.
Fertilizing at the right time builds deep roots for summer survival. Bermuda and Zoysia respond quickly; Centipede grows more slowly but requires less maintenance.
8. Aerate or Dethatch (Only if Needed)
Clay soil can compact fast, especially in high-traffic yards. Thatch over 0.5 inches can block water and nutrients.
What to do:
- Use a core aerator to pull plugs from compacted areas.
- Dethatch only if the layer is thick and the lawn is fully growing.
When to do it: Late May to June, once your grass is actively growing.
Gary Forrester, a Horticulture Extension Agent at Horry County Extension Service, Clemson University, also points out that “removing thick thatch layers in spring in warm-season lawns will keep the growing points of the turf close to the soil surface, which will help protect the buds from freezing temperatures later in the year.” Spring dethatching not only improves nutrient and water uptake now but also helps your lawn survive winter stress better.
