The Best Time to Fertilize Your Lawn for Maximum Growth

If you're a homeowner in Spartanburg, you already know how important a healthy lawn is - especially during the warm months when everything's in full bloom. But when it comes to fertilizing, timing really is everything. Apply too early, and you risk wasting product. Too late, and you miss the prime growing season. So, when's the right time to fertilize your lawn for the best results? Let's break it down.
Understanding Grass Types in South Carolina
Most lawns in Spartanburg feature warm-season grasses like Bermuda, Zoysia, or Centipede. These grasses have specific needs and thrive during our hot, humid summers. For warm-season lawns, the best fertilization window typically falls between late April and early September - with the first application right as the grass starts greening up in spring.
Spring Is Key
The first big feeding should come around mid to late April, once soil temps hit about 65°F. That's usually when your lawn wakes up from its winter nap. This early boost helps fuel strong root growth and gives your grass the energy it needs to spread and fill in bare patches.
Summer Feeding
Follow up with a second application in mid to late summer - July or August is a good bet. This helps the lawn stay thick and green even through the heat. Just avoid fertilizing during droughts or extremely dry periods, unless you're actively watering your lawn.
Avoid Late Fall Fertilizing
Once temps start to drop and your lawn slows down, fertilizing won't do much. In fact, feeding too late can make your grass more vulnerable to cold damage. That's why September is usually the latest you'll want to apply fertilizer here in the Upstate.
What About Fertilizer Type?
Use a balanced, slow-release fertilizer specifically labeled for warm-season grasses. If you've got pets or kids, look for a pet-safe option. Spartanburg's clay-heavy soil can benefit from a custom blend - something Longleaf Turf Pros can tailor based on your yard's unique needs.
