Warm-season lawns don't grow on the same schedule as the grass up north, so the fertilizing calendar looks a little different too. If you're maintaining a lawn in Atlanta or Charlotte, timing your feedings around how your grass actually grows each season makes the difference between a lawn that thrives and one that just survives.
Here's how to time your fertilizer applications through the year, and why the schedule matters just as much as the product itself.
Why Timing Matters More Than You'd Think
Bermuda and zoysia are warm-season grasses. They actively grow during the warmer months and go dormant once temperatures drop in the winter. Feeding your lawn when it isn't actively growing can encourage the kind of shallow root growth that leaves your yard more vulnerable to weeds, disease, and drought stress later on.
The right approach follows your grass's natural growth cycle: light in early spring, steady through summer, tapering off before dormancy, and off entirely in winter.
Early Spring (Late March–April): Wait for Green-Up
It's tempting to fertilize the moment the weather warms up, but the better move is to wait until your lawn has fully greened up, typically when you've mowed it two or three times. Fertilizing bermuda or zoysia too early, while the grass is still transitioning out of dormancy, can feed weeds more than your turf.
Once green-up is complete, a light nitrogen application helps kickstart healthy growth for the season ahead.
Late Spring Into Summer (May–August): Peak Growing Season
This is when bermuda and zoysia do most of their growing, and it's also when your lawn benefits most from consistent feeding. In the Atlanta and Charlotte climate, this typically means multiple lighter applications spaced through the growing season rather than one heavy dose. Splitting feedings this way supports steady, even growth and helps your lawn hold up against summer heat and foot traffic.
This is also a good window to address soil health more broadly. Healthy, well-fed soil grows grass with deeper roots, and deeper roots are naturally more resistant to the pests, disease, and drought stress that show up during a hot Southeast summer.
Early Fall (September): Last Feeding Before Slowdown
As temperatures start to ease, bermuda and zoysia growth begins slowing down in preparation for dormancy. A final light feeding in early fall gives your lawn the reserves it needs to stay resilient through the cooler months without pushing new growth so late that it gets caught off guard by a frost.
This is also the point where many Atlanta and Charlotte lawns benefit from aeration, since it helps whatever you feed your lawn actually reach the roots instead of sitting on compacted soil. Humates play a role here too, helping soil hold onto and deliver nutrients more effectively.
Late Fall and Winter (October–February): Hold Off
Once your bermuda or zoysia lawn goes dormant, it's generally time to stop feeding it. Applying a fast-release fertilizer when the grass isn't actively growing won't do much for your lawn and may encourage winter weeds instead. Our organic fertilizer works differently, though. Because it continues breaking down over time, nutrients build up in the soil and help support a stronger spring green-up. That's why we typically make a later fertilizer application than providers using synthetic products. Otherwise, this is the season to let your lawn rest and focus on winter weed prevention while your warm-season turf isn't actively growing.
A Simpler Way to Think About It
If there's one rule to hold onto, it's this: feed your lawn when it's actively growing, and leave it alone when it isn't. For Atlanta and Charlotte's bermuda and zoysia lawns, that means light feeding in early spring, consistent applications through summer, one last light round in early fall, and a full pause through winter dormancy.
Every yard is a little different, though. Soil condition, shade, foot traffic, and grass type all affect the right schedule for your property. If you'd rather have a program built around your lawn's specific growing pattern instead of guessing at timing, our fertilization program uses soil-focused, chemical-free amendments designed to work with your lawn's biology rather than against it, timed to when your grass can actually use them.
FAQs
Can I fertilize bermuda or zoysia grass in the winter?
No. Both grasses go dormant in the winter and aren't actively absorbing nutrients, so fertilizing during this window mostly ends up feeding winter weeds instead of your lawn.
How many times a year should I fertilize warm-season grass?
Most bermuda and zoysia lawns in the Atlanta and Charlotte area do best with several lighter applications spread from spring green-up through early fall, rather than one or two heavy feedings.
What happens if I fertilize too early in spring?
Fertilizing before your lawn has fully greened up can end up feeding cool-season weeds more than your turf, since your grass isn't actively growing yet.
