Top 10 Lawn Care Tips Every Homeowner in Columbia, SC Should Know

1. Understand Your Grass Type

Most lawns in Columbia feature warm-season grasses like Bermuda, Zoysia, or Centipede. These thrive in heat but need proper care to stay green and dense.

Tip: Identify your grass type before choosing fertilizers, mowing heights, or watering routines. For example, Bermuda grass should be mowed lower than Zoysia, and each has different nutrient needs.

2. Mow at the Right Height (and Frequency)

Mowing too low can weaken your lawn, while letting it grow too tall invites pests and disease. In Columbia’s climate, grass grows fast—especially in spring and summer.

Tip:

• Bermuda grass: 1–1.5 inches
• Zoysia grass: 1.5–2.5 inches
• Centipede grass: 1.5–2 inches

Stick to the one-third rule: never cut more than one-third of the grass blade at once.

3. Water Deeply, Not Daily

It’s tempting to water your lawn every day in the South Carolina heat, but deep, infrequent watering is better for root development.

Tip: Water early in the morning, 2–3 times per week, delivering about 1 inch of water per week, including rainfall. Avoid watering in the evening to reduce the risk of fungal diseases.

4. Fertilize with Purpose

Your lawn's nutrient needs vary depending on grass type and season. Over-fertilizing can do more harm than good—especially in Columbia’s hot summers.

Tip:

• Apply fertilizer during active growing seasons (late spring through summer for warm-season grasses).
• Use a slow-release nitrogen blend, and always follow the label.
• Avoid fertilizing in high heat (above 90°F).

5. Prevent and Control Weeds Early

In Columbia, crabgrass and clover are some of the most common weed issues. The key to preventing them is stopping them before they sprout.

Tip: Use a pre-emergent herbicide in early spring (February to March) before soil temperatures reach 55°F. For existing weeds, use spot treatments with a selective herbicide.

6. Aerate Your Lawn Annually

Heavy clay soils are common in the Midlands region of South Carolina, and over time, they compact. Compacted soil restricts root growth and water absorption.

Tip: Aerate your lawn once a year—ideally in late spring—using a core aerator. This allows oxygen, nutrients, and water to penetrate deeper into the soil.

7. Watch Out for Lawn Pests

Warm climates like Columbia’s are a hotspot for pests like grubs, armyworms, fire ants, and chinch bugs. These insects can destroy large sections of your lawn before you even notice.

Tip: Inspect your lawn regularly for brown patches, thinning grass, or small mounds. Use targeted pest control solutions and consider seasonal lawn treatments to keep pests at bay.

8. Dethatch When Necessary

Thatch—a layer of dead grass and roots—can prevent water and nutrients from reaching the soil if it becomes too thick (over ½ inch).

Tip: Check for thatch buildup by cutting out a small square of lawn. If it’s too thick, dethatch in late spring or early summer, using a dethatching rake or machine.

9. Use Mulching Mowers or Grasscycling

Instead of bagging your clippings, consider mulching or grasscycling—letting grass clippings fall and decompose naturally.

Tip: This returns valuable nutrients to your soil, reduces waste, and keeps your lawn greener. Just be sure your mower blade is sharp and clippings are short enough not to smother the grass.

10. Hire Local Lawn Experts for Seasonal Help
