Aiken SC Lawn Care Calendar
Month-by-Month Guide for Zone 8a
Generic lawn apps give you Ohio advice. Aiken's warm-season calendar is completely different — here's exactly what to do every month for Bermuda, Centipede, and Zoysia in the SC Midlands.
Quick Summary — Aiken SC Lawn Care Timing
Apply pre-emergent before soil hits 55°F (late Feb–mid March). Fertilize after full green-up in April–May. Centipede: only once in May–June. Aerate in September–October. Apply fall pre-emergent in early October. Fire ants surge every April after first warm rains. Mosquito control: April through October.
Month-by-Month Aiken Lawn Guide
What to Do Every Month in Your Aiken SC Lawn
JANDormancy
January — Rest & Plan
- Lawn fully dormant — brown is completely normal
- Schedule spring program with your lawn care provider
- Soil pH correction — lime if needed, won't stress dormant grass
- Watch for early warm spells that prompt premature green-up
FEBPre-Emergent
February — Pre-Emergent Window Opens
- Monitor soil temperature — must apply pre-emergent before 55°F
- Watch for forsythia blooming — nature's 55°F soil temperature signal
- Late February: apply pre-emergent if warm spell pushes temps up early
- Send soil sample to Clemson Extension while lawn is dormant
MARPre-Emergent
March — Pre-Emergent Application
- Apply pre-emergent (prodiamine) before soil hits 55°F
- Do NOT apply weed-and-feed on Centipede during green-up
- Centipede begins greening late March — do not fertilize yet
- First fire ant mound activity of the season — prepare
APRGreen-Up
April — Green-Up & First Fertilizer
- Begin mowing as Bermuda and Zoysia fully green up (mid-April)
- First fertilizer after 100% green-up — Bermuda: 1 lb N/1,000 sqft
- Fire ant mounds surge after warm rains — schedule whole-yard treatment
- Watch for slime mold after heavy rains — ugly but harmless
MAYGrowing Season
May — Peak Growth Begins
- Increase mowing frequency — Bermuda every 5–7 days
- Centipede ONLY fertilizer application: 15-0-15 at 1 lb N/1,000 sqft
- Mosquito control barrier treatment — season is underway
- Watch for armyworm activity — birds gathering in lawn are first sign
JUNPeak Season
June — Peak Season & Pest Pressure
- Bermuda grows 1"+/week — mow every 5–7 days, follow one-third rule
- Peak mosquito season — monthly barrier spray
- Second Bermuda fertilizer (1 lb N/1,000 sqft)
- Brown patch fungus risk — avoid late-evening irrigation
JULHottest Month
July — Manage, Don't Stress
- 91°F avg high in Aiken — water 1 inch/week if no rain
- Continue mowing frequency — slowing down causes scalping
- Armyworm peak — check every few days for irregular brown patches
- Grubs beginning root feeding — spongy turf that pulls up easily
AUGLate Summer
August — Last Push Before Fall
- Continue mowing — don't let grass get ahead before fall
- Grub damage most visible — brown patches that peel like carpet. Treat immediately.
- Last effective Bermuda fertilizer before September 15 cutoff
- Nutsedge thrives in heat and humidity — treat with sedge-specific herbicide
SEPAeration
September — Core Aeration Window
- BEST window for core aeration — grass still growing, recovers before dormancy
- Apply fall pre-emergent early-to-mid October for winter annual weeds
- Continue mosquito program through October
- Overseed thin Bermuda or Zoysia areas while soil is still warm
OCTFall Prep
October — Fall Pre-Emergent & Winterizer
- Apply fall pre-emergent (early October) for poa annua, henbit, chickweed
- Winterizer fertilizer — potassium-focused for root strength
- Reduce mowing frequency as growth slows dramatically
- Fire ants have a second activity surge in October — check for mounds
NOVDormancy
November — Into Dormancy
- Bermuda, Zoysia, Centipede begin going brown as temps drop below 50°F
- Final leaf cleanup before full dormancy
- Equipment maintenance — sharpen mower blades for spring
DECFull Dormancy
December — Rest
- Lawn fully dormant — brown is completely normal, grass is not dead
- Plan next year's lawn program
- Soil testing if you haven't done one this year

| Centipede | May–June only (once) | 1.5 – 2 inches | Never over-fertilize — Centipede Decline |
| Zoysia | May – July | 1 – 2 inches | Be patient — greens up last in spring |
