Lawn Care Schedule for Amarillo, Texas
Zone 7a enjoys mild winters with lows rarely reaching 0°F and a growing season that stretches from early March into November. This is prime territory for tall fescue in the East and drought-tolerant warm-season grasses farther west, with the critical pre-emergent window arriving in early March.
Texas spans multiple climate zones — Houston follows South belt timing, Dallas follows Transition timing, and west Texas requires drought-adapted management — so local conditions should guide treatment schedules rather than statewide averages.

Recommended Grass Types for Amarillo
Month-by-Month Treatment Calendar
Purchase supplies; the Texas Panhandle's high elevation and continental climate push green-up later than the rest of the South belt
Apply crabgrass preventer as soil crosses 50–55°F, typically early-to-mid April here
Green-up begins later than most of the South belt due to Panhandle elevation and frequent late-spring frosts
First feeding once warm-season grass is fully green
Treat emerged weeds before summer heat
Continue feeding through peak spring growth
Aerate to relieve compaction in the region's heavy clay and caliche soils
Summer feeding continues
Deep watering essential — low humidity and near-constant wind drive fast evaporation
Peak summer heat, though nights cool more than lower-elevation Texas thanks to the Panhandle's altitude
Preventative application as beetle eggs are laid
Last summer feeding — stop 6–8 weeks before the first frost, which arrives earlier here than in the rest of the South belt
Continue irrigation through late-summer heat
Final feeding before dormancy — the Panhandle's first fall frost typically lands in early-to-mid October
Gradually lower mowing height as growth slows toward an earlier dormancy than the rest of the South belt

Fertilization
Feed your lawn at the right time — not on the bag's schedule.
Pre-Emergent
Stop crabgrass before it starts — timing is everything.

Kill the weeds that are already there — selectively and safely.
Aeration
Break up compaction and open the soil to water, air, and nutrients.
Watering
Water deep and infrequent — not shallow and daily.
Mowing
The one-third rule changes everything about how your lawn looks.
Grub Control
Prevent root damage before you see it — curative treatments are less effective.
