When should you fertilize and aerate a lawn in Georgetown?
Make the first fertilizer application in April or May, but only after the lawn has fully greened up and been mowed at least twice, proof it is actively growing. Core-aerate in spring or early summer while the grass recovers fast. Both windows are driven by Georgetown's frost dates and the warm-season growth cycle, not the calendar alone.
The Georgetown lawn care calendar
This calendar covers Central Texas warm-season grasses: St. Augustine, Bermuda, and Zoysia. The timing reflects Williamson County's growing season and the historic frost window; adjust by a week or two for an early or late spring.
| Task | Spring | Summer | Fall | Winter |
|---|---|---|---|---|
| Pre-emergent weed control | Late Feb – mid Mar (crabgrass) | — | Mid Aug – mid Sep (winter weeds) | — |
| Fertilize | First feed after green-up + 2 mowings (Apr–May) | Hold during drought stress | Final nitrogen 4–6 wks before first frost | None (dormant) |
| Core aerate | Optimal window (Apr–May) | Early summer OK | — | — |
| Pest watch | — | Chinch bugs + white grubs (~July) | — | — |
| Mowing | Resume as growth starts | Weekly to bi-weekly | Taper with growth | Little to none |
| Irrigation | As needed; rely on rain | Deep + infrequent, cycle-and-soak | Reduce as temps drop | Off or minimal |

Detailed windows
- Apply spring pre-emergent to stop summer annual weeds like crabgrass before they germinate.

- Fertilize only after full green-up and at least two mowings, proof the lawn is actively growing.
- Apply nitrogen at 0.5 to 1.0 pound per 1,000 square feet.
- Core-aerate now: spring and early summer are the optimal windows on clay.
- Do not fertilize during hot, dry, drought-stressed periods.
- Apply preventative white-grub treatment around July.
- Watch for chinch bugs in St. Augustine: the hot, dry summer check window.
- Apply fall pre-emergent to control winter annuals like annual bluegrass and rescuegrass.

- Apply the final nitrogen of the year at least 4 to 6 weeks before the historic first frost to prevent winter kill and disease.
- The turf is dormant: apply no nutrients, and turn off or drastically reduce automated irrigation.

How do frost dates drive the Georgetown lawn calendar?
Frost dates set the start and end of the active lawn season. In spring, wait until the threat of frost passes, the turf fully greens up, and you have mowed at least twice before the first fertilizer application. In fall, apply the final nitrogen 4 to 6 weeks before the historic first frost so the grass hardens off instead of pushing tender growth into a freeze. After the first hard frost, a seasonal cleanup clears leaf litter and spent growth so the dormant lawn is not smothered through winter.
Georgetown's growing season runs roughly seven to nine months: from the last spring frost (usually mid-March) to the first fall frost (usually early December). That long window is why warm-season grass dominates here. Source: Texas A&M AgriLife Extension. See the Georgetown watering guide for the irrigation side of the calendar.
