Georgetown TX homeowners often ask when to start their spring lawn care routine. The answer depends on your grass type and soil temperature — not the calendar date.
Georgetown TX lawn care operates on a different calendar than the rest of the country. While northern homeowners are still digging out from late snowfalls in April, Georgetown yards can be showing strong active growth as early as late February or early March in a warm year.
Understanding that calendar — not the national lawn care guides you find on most websites — is the difference between a thriving Georgetown lawn and an expensive, frustrating struggle.
The Key Number: Soil Temperature
Forget the date on the calendar. The number that actually matters for starting your Georgetown lawn care season is soil temperature at a 2-inch depth.
For warm-season grasses (Bermuda, St. Augustine, Zoysia — the three most common in Georgetown), meaningful active growth begins when soil temperatures consistently reach 65°F. This is also the threshold for applying pre-emergent herbicides to prevent crabgrass and other summer annual weeds.
In Georgetown and Williamson County, that soil temperature threshold typically hits between late February and mid-March, though it can swing earlier or later depending on the winter we've had.
Month-by-Month Georgetown Lawn Care Calendar
February
- Monitor soil temperature with a probe thermometer (available at any garden center)
- Apply pre-emergent herbicide when soil temps hit 50°F at 2-inch depth — this prevents early germinating weeds before they emerge
- Service your irrigation system before you need it — fix broken heads, check zones, and calibrate run times
- Crape myrtles and other woody ornamentals: prune now before new growth begins
March
- Apply your first round of lawn fertilization once soil temps hit 65°F and grass shows clear green-up
- Watch for winter weeds that survived — spot treat with selective post-emergent if needed
- Begin weekly mowing once your grass is actively growing (Bermuda mowing season typically starts in March most years in Georgetown)
- Overseed any bare or thin areas before summer heat arrives
April–May
- Mowing is in full swing — most Georgetown Bermuda lawns need weekly service by April
- Apply second round of fertilizer (typically a 4-week interval from your first application)
- Apply second pre-emergent treatment in May before soil temps climb above 90°F
- Schedule core aeration for thin or compacted lawns — late April through May is ideal for warm-season grasses
June–August
- Raise mowing height slightly during peak summer heat to reduce stress (Bermuda: 1.5–2.5 inches; St. Augustine: 3–4 inches)
- Deep, infrequent irrigation is critical — Georgetown's clay soils absorb water slowly; multiple short cycles allow better absorption
- Adjust irrigation for EPCOR/Georgetown water restrictions — typically two allowed watering days per week during summer
- Watch for chinch bugs in St. Augustine lawns during July and August heat
September–October
- Fall fertilization is critical — apply a balanced or potassium-rich fertilizer in September after the worst heat breaks
- If you're overseeding with ryegrass for winter color, mid-October is the ideal window as Bermuda enters dormancy
- Aeration + overseeding combination works best in September for warm-season grass thickening before dormancy
November–January
- Bermuda, Zoysia, and buffalo grass enter dormancy — they'll look tan/brown until spring, which is completely normal
- St. Augustine may stay partially green in mild winters but growth slows dramatically
- Minimal mowing needed during dormancy
- Apply pre-emergent for cool-season annual weeds (henbit, chickweed) in November
The Biggest Georgetown Lawn Care Mistakes by Season
Spring: Applying fertilizer too early (before green-up) or too late (missing the spring growth window). Getting the timing right by watching soil temps rather than calendar dates makes a significant difference.
Summer: Mowing too short during heat stress. Georgetown's summers are long and brutal — a Bermuda lawn scalped to 1 inch will struggle through August far more than one maintained at 2 inches.
Fall: Skipping fall fertilization. This is arguably the most important single application of the year — it fuels root development and stores energy for the strongest possible spring green-up.
Winter: Overwatering dormant turf. Dormant warm-season grasses need very little water. Overwatering during dormancy can create fungal disease conditions, especially in years with mild, wet Georgetown winters.
