When Should I Fertilize My Lawn?

The right fertilization window depends on your grass type. In the Charlotte and Lake Norman region, warm-season grasses like Bermuda and Zoysia should be fertilized from late April through midsummer, while cool-season fescue thrives with a fall feeding in September or October. Applying fertilizer outside these windows can stress your lawn or fuel weed growth.

Know Your Grass Type First

North Carolina lawns typically fall into two categories: warm-season and cool-season. Warm-season grasses go dormant in winter and actively grow from late spring through summer. Cool-season grasses like tall fescue peak in fall and spring, making those the ideal feeding windows.

Warm-Season Grasses (Bermuda, Zoysia, Centipede)

Wait until soil temperatures consistently reach around 65°F — typically late April to early May in the Charlotte area. A second application in early-to-mid summer supports continued growth. Avoid fertilizing after late August, as it can push tender growth vulnerable to frost.

Cool-Season Grasses (Tall Fescue)

Early fall — September through mid-October — is the prime window. A secondary light feeding in early spring can help, but heavy spring fertilization often encourages disease and summer burnout. Avoid fertilizing fescue in peak summer heat entirely.

General Tips

• Always do a soil test before fertilizing to identify what your lawn actually needs.
• Water lightly after application to help nutrients absorb without runoff.
• Slow-release fertilizers typically provide more even feeding over time.
• Never fertilize a drought-stressed lawn — hydrate it first.
