When cooler temperatures arrive in Georgia, many homeowners assume lawn care can take a break until spring. However, winter lawn care is still important, and understanding when to fertilize your grass can make a significant difference in how your lawn performs throughout the year.
The answer to whether you should fertilize your lawn in winter depends largely on the type of grass growing in your yard. Bermuda, Zoysia, and Tall Fescue all have different nutrient requirements, and applying fertilizer at the wrong time can do more harm than good.
Here’s what Georgia homeowners need to know about winter lawn fertilization.
1. Understanding Warm-Season vs. Cool-Season Grasses
Georgia homeowners commonly have one of two categories of turfgrass: warm-season or cool-season grasses.
Warm-season grasses, such as Bermuda and Zoysia, thrive during the warmer months. As temperatures drop in fall, these grasses naturally enter dormancy. Their growth slows significantly, and their green color fades to brown or tan.
Cool-season grasses, such as Tall Fescue, behave differently. They grow most actively during the cooler months of fall and spring, making winter an important part of their growing season.
Understanding which type of grass you have is the first step toward developing an effective fertilization schedule.
2. Should You Fertilize Bermuda and Zoysia in Winter?
In most cases, no.
Bermuda and Zoysia are warm-season grasses that enter dormancy as temperatures decrease. Once dormant, these grasses are no longer actively growing and have limited ability to utilize the nutrients supplied by fertilizer.
Applying nitrogen fertilizer to dormant Bermuda or Zoysia is generally unnecessary and can encourage undesirable weed growth rather than benefit your turf.
For most Georgia lawns, the best approach is to complete the final fertilizer application while the grass is still actively growing in the fall, then wait until spring green-up before resuming regular fertilization.
When should you fertilize Bermuda and Zoysia?
– Spring: Begin fertilization after the grass has fully greened up and is actively growing.
– Summer: Continue fertilization according to the grass type, soil conditions, and recommended application schedule.
– Fall: Reduce or discontinue nitrogen applications as the grass approaches dormancy.
– Winter: Avoid routine nitrogen fertilization while the grass is dormant.
Proper timing helps encourage healthy growth while reducing unnecessary fertilizer applications.
3. What About Tall Fescue Lawns?
Tall Fescue is different from Bermuda and Zoysia because it is a cool-season grass.
Unlike warm-season grasses, Tall Fescue does not go dormant during Georgia’s winter months under typical conditions. It generally grows actively during fall and spring, making these seasons important for fertilization.
For established Tall Fescue lawns, fall is typically the most important fertilization period. A properly timed fall fertilization program helps support root development, turf density, and overall lawn health.
A lighter winter application may be appropriate in some situations, depending on soil test results, turf condition, and previous fertilizer applications.
However, homeowners should avoid automatically applying fertilizer simply because the calendar says it is winter. A soil test and an understanding of the lawn’s nutritional needs are much better guides.
4. Winter Is a Great Time to Focus on Weed Control
Even though warm-season grasses are dormant, many weeds continue growing throughout Georgia’s winter.
Common winter lawn weeds include:
– Annual bluegrass (Poa annua)
– Chickweed
– Henbit
– Purple deadnettle
– Hairy bittercress
– Carolina geranium
These weeds can become particularly noticeable in dormant Bermuda and Zoysia lawns because the brown turf provides little competition against actively growing weeds.
Winter is an important time to manage these weeds before they mature, spread, and produce seeds.
A properly timed weed-control program can help reduce winter weed pressure and improve the appearance of your lawn heading into spring.
Keep in mind that herbicide selection and application timing should always account for the turfgrass species, weed being targeted, and product label instructions.
5. What Should You Do for Your Lawn During Winter?
Although fertilization may be limited during winter, there are several things homeowners can do to prepare their lawns for a successful spring.
Continue monitoring weeds. Winter weeds can spread quickly when left untreated. Identifying and managing them early can help reduce problems later.
Keep leaves and debris off the lawn. Heavy accumulations of leaves can block sunlight and trap moisture, potentially contributing to turf problems.
Avoid unnecessary fertilizer applications. Applying fertilizer when grass cannot effectively use it wastes money and may contribute to nutrient runoff.
Evaluate your lawn’s condition. Winter is a good time to identify thin areas, drainage problems, soil compaction, and other issues that may need attention before spring.
Plan your spring pre-emergent application. Preventing summer weeds starts before they become visible. Properly timed pre-emergent applications help prevent many annual weeds from establishing in your lawn.
6. Get Your Georgia Lawn Ready for Spring
One of the biggest mistakes homeowners make is waiting until spring weeds and lawn problems become noticeable before taking action.
A successful lawn-care program is built around proper timing and consistency. Pre-emergent weed control, fertilization, and post-emergent weed treatments all play important roles in maintaining a healthy lawn.
For Bermuda and Zoysia lawns, spring green-up is an important milestone. Fertilization should resume once the turf has fully greened up and is actively growing.
For Tall Fescue lawns, maintaining proper nutrition through the fall and spring growing seasons is essential.
Every lawn is different, and the best treatment schedule depends on grass type, soil conditions, weed pressure, and the overall condition of the property.
