North Alabama's climate creates unique opportunities — and challenges — for lawn fertilization. Get the timing wrong, and you'll waste money and potentially damage your grass. Get it right, and you'll have the greenest lawn on the block.
Warm-Season vs. Cool-Season Grasses
Most North Alabama lawns feature warm-season grasses like Bermuda, Zoysia, or St. Augustine. These grasses go dormant in winter and actively grow from late spring through early fall. This growth cycle determines when and how often you should fertilize.
The North Alabama Fertilization Calendar
April–May: Apply your first fertilizer of the season once soil temperatures consistently reach 65°F. This is typically when you see your lawn "green up" after winter dormancy. Use a balanced fertilizer or a product with slightly higher nitrogen.
June–July: A second application in early summer keeps growth going strong through the hottest months. Avoid fertilizing during extreme heat (above 95°F) to prevent burning.
August: A light application in late summer helps the lawn recover from summer stress and prepare for fall.
September: Your last fertilization should be no later than mid-September. Fertilizing too late in fall can stimulate growth that won't harden off before the first frost, making your lawn more susceptible to winter damage.
What About Fall and Winter?
Skip fertilizing from October through March for warm-season grasses. The lawn is dormant or semi-dormant and won't benefit — and you'll just be feeding weeds.
If you have a cool-season grass (like fescue) overseeded for winter color, you can apply a starter fertilizer at overseeding time in October.
