Grass-specific care
Why Centipede Grass Needs Different Fertilization
Centipede Grass has unique characteristics that affect how lawn fertilization should be applied. Centipede grass is highly sensitive to many common herbicides and over-fertilization. Product selection is critical.
Getting the product, rate, and timing wrong doesn't just waste money — it can damage your lawn. We match every treatment to your specific grass type.

Our approach
Fertilization for Centipede Grass in Georgia
Centipede needs the least fertilizer of any warm-season grass — just 1-2 lbs of nitrogen per 1,000 sq ft annually. Over-fertilizing centipede causes iron chlorosis, excessive thatch, and centipede decline. We apply light, measured doses during active growth and supplement with iron for color rather than pushing nitrogen for green-up.
Treatment timing
When to Apply Fertilization to Centipede Grass
Spring
Light nitrogen after centipede is fully green (late May). Iron for color without growth push.
Summer
One measured nitrogen application. Iron supplementation as needed for color.
Fall
No nitrogen. Potassium only to harden turf before winter.
Winter
No fertilizer of any kind. Feeding dormant centipede promotes decline.
Results timeline
What to Expect After Treatment
Color improves within 2-3 weeks of iron application without excess growth
Centipede maintains medium green color (not dark green like bermuda)
Growth rate stays manageable — lower mowing frequency than over-fed lawns
No iron chlorosis (yellowing) when nitrogen rates are properly calibrated
Lawn enters dormancy with healthy root reserves for spring recovery

Common questions
Centipede Grass Fertilization Questions
Why does my centipede turn yellow when I fertilize it?
Centipede is extremely sensitive to excess nitrogen. Too much nitrogen triggers iron chlorosis — the grass can’t absorb iron fast enough to match the nitrogen-driven growth, turning leaves yellow. This is the most common centipede care mistake in Middle Georgia. We keep nitrogen rates at 1-2 lbs per 1,000 sq ft maximum.
Should I use the same fertilizer as my neighbor with bermuda?
Absolutely not. Bermuda needs 4-5 lbs of nitrogen per year; centipede needs 1-2 lbs. Applying bermuda-rate fertilizer to centipede is one of the fastest ways to destroy it. We use centipede-specific blends with lower nitrogen and supplemental iron to achieve good color without the growth surge that causes decline.
What is centipede decline?
Centipede decline is progressive thinning and dieback caused by a combination of over-fertilization, improper pH, cold stress, and thatch buildup. It usually starts with patches that thin and yellow, then spreads over seasons. The primary trigger in Middle Georgia is applying too much nitrogen — the lawn looks great for a few weeks, then declines rapidly.
How often do you fertilize?
We fertilize on most visits — 6-8 times per year. The blend and rate change with the seasons to match your grass type’s growth cycle.
Can you over-fertilize a lawn?
Yes, and it causes more harm than good. We use calibrated rates for your specific grass type. Centipede, for example, needs far less nitrogen than bermuda.
