Fertilizing Centipede Grass in Alabama: Fertilizer Ratios and Weed Control Options

Fertilizing Centipede Grass in Alabama: Fertilizer Ratios and Weed Control Options

You run a lawn care business in South Alabama. Your client has centipede grass mixed with other types. The standard recommendation is 15-0-15, but you have 24-2-11 (Lesco). Can you use it?

Fertilizer Analysis

24-2-11 is higher in nitrogen, which will green up foliage faster. That’s not inherently bad—centipede responds to nitrogen—but excess nitrogen invites disease and thatch. Follow the bag rate: typically 4.2 lbs per 1,000 sq ft. Split applications are safer than one heavy dose.

Weed Control

You didn’t specify the weeds. MSMA (a selective post-emergent) controls many broadleaf and grassy weeds but not nutsedge. For nutsedge, you’ll need a targeted product like halosulfuron or sulfentrazone. Always verify state registration and label restrictions before applying.

Best Practice

• Soil test first—centipede prefers pH 5.0–6.0.
• Apply nitrogen sparingly (1–2 lbs N/1,000 sq ft/year).
• Use the right herbicide for the specific weed spectrum.
• Document everything for your client.

Higher-nitrogen fertilizer works, but with centipede, less is usually more. Tailor the program to the soil test and the weed pressure.
