Round Rock Lawn Care Calendar: A Month-by-Month Guide for Central Texas

Winter (December-February): Dormancy and Pre-Emergent Prep

Warm-season grass is dormant and brown through winter, and that is normal - a dormant lawn is not a dead lawn. Your main jobs are staying off frozen or soggy turf, keeping leaves cleared so the crown can breathe, and getting your mower serviced before spring. Overwatering dormant grass in a wet winter does more harm than good, since Blackland clay holds moisture for days and can rot crowns that sit saturated.

The one time-sensitive task is the spring pre-emergent, and it happens at the tail end of winter. A pre-emergent herbicide creates a barrier that stops crabgrass and other summer weeds before they sprout, but it only works if it is down before the seeds germinate.

• Late February to early March: apply pre-emergent before soil temperatures reach 55 degrees for several days - roughly when redbuds start to bud.
• Keep foot traffic off frost-covered grass; walking on frozen blades bruises them and leaves brown footprints for weeks.
• Clear fallen leaves so dormant crowns are not smothered through wet stretches.
• Service the mower, sharpen the blade, and plan any irrigation repairs before the growing season starts.

Spring (March-May): Green-Up, First Feed, and Mowing Returns

Spring is when the lawn wakes up, and the biggest mistake is fertilizing too early. Feeding before the grass is actively growing feeds weeds instead and can push tender growth into a late frost. Wait until the lawn has fully greened up and you have mowed it a couple of times - usually April in Round Rock - then apply a balanced, slow-release fertilizer.

Resume mowing as growth picks up, and drop the height for the first cut or two to remove winter-browned tips, then settle into your summer height. Spring is also the prime planting window: soil is warm enough for roots to establish but the brutal heat has not arrived, making March through May the best stretch to lay new sod or overseed thin areas. If you are renovating a lawn, do it now rather than gambling on a summer install.

Watch for the first weeds the pre-emergent missed and spot-treat them while they are small. A dense, well-fed lawn is your best weed control - thick turf shades out most invaders before they get established.

Spring is also the moment to check your irrigation before the heat arrives, not after. Run each zone, look for broken or misaimed heads, and confirm coverage while you can still fix problems calmly. Discovering a dead zone in July, with the lawn already stressed and watering days restricted, turns a simple repair into an emergency. A ten-minute walkthrough now prevents brown patches later.

Summer (June-August): Peak Growth, Deep Watering, Heat Stress

Summer is warm-season grass at its best and your watering discipline at its most tested. The goal is deep, infrequent watering that trains roots downward - typically about one inch per week including rainfall, delivered in one or two soakings rather than daily sprinkles. Shallow daily watering builds shallow roots that fry in a heat wave. Round Rock's watering windows apply here: water before 10 a.m. or after 7 p.m. on your designated days to cut evaporation and comply with city rules.

Raise your mowing height in summer. Taller blades shade the soil, hold moisture, and protect roots from heat, so let St. Augustine run toward the top of its range and give Bermuda and Zoysia a little extra length in July and August. Mow often enough that you never remove more than a third of the blade at once, and leave the clippings to return nutrients.

One firm rule: do not lay new sod in mid-August. It is the harshest planting window of the year - new roots cannot establish fast enough to survive the heat, and you will fight to keep it alive. If a lawn project comes up in late summer, either water an existing lawn through it and wait for fall, or plan the install for September once the worst heat breaks.

Fall (September-November): Recovery, Final Feed, and Overseeding

Fall is the second great window for lawn work. The heat eases, rainfall often returns, and soil stays warm enough for roots to grow, so early fall is an excellent time to install sod, repair summer damage, and let the lawn recover its density before dormancy. If you skipped a spring renovation, September is your chance.

Time your last nitrogen feeding for early fall - roughly six to eight weeks before the expected first frost, which in Central Texas usually lands in late November or early December. Feeding too late pushes tender growth that a freeze will damage, so once you are inside that window, stop the nitrogen and let the grass harden off naturally. A fall application of potassium can help the lawn build cold tolerance without forcing top growth.

This is also the season to plan next year: audit your sprinkler coverage, note dry spots for spring repairs, and consider a smart controller that adjusts runtimes automatically. Getting drainage and irrigation issues on the calendar now means they are fixed before the next growth cycle.

One caution specific to our climate: do not be alarmed when the lawn browns after the first hard frost. Warm-season grasses go fully dormant and turn tan for the winter, and that dormancy is a survival mechanism, not a sign of a dying lawn. Resist the urge to overwater or fertilize brown grass to green it up - it will not respond, and the effort mostly wastes water or feeds cool-season weeds. Let it rest, and it will green up on its own when soil warms in spring.
