Austin does not have four equal seasons. It has two good planting windows (spring and fall), five months of heat that kills new plants (May through September), and a short unpredictable winter. Timing your landscaping project around this reality is the difference between plants that thrive and plants that die in their first summer. Here is the month-by-month guide.

Best Timing by Project Type

Trees

Plant trees from October through February. A tree planted in November gets 6 months of cool-season root growth before its first Austin summer. The same tree planted in April gets 6 weeks. Fall-planted trees are measurably larger and healthier by the end of their first year than spring-planted trees of the same size at installation. Evergreen trees can also be planted in early spring (March) with good results.

Shrubs and perennials

Two windows: March through mid-April and October through November. Fall is better for native plants and adapted shrubs because they establish roots through winter and are ready for summer. Spring is fine if you can commit to watering through the first summer.

Sod (lawn installation)

Grass TypeBest Install WindowAvoid
BermudaMarch–May (spring growth)November–February (dormant)
St. AugustineMarch–April or Sept–OctJune–August (heat stress)
ZoysiaMarch–MayNovember–February
Buffalo grassMarch–MayNovember–February

All warm-season grasses should be installed during active growth periods. Installing Bermuda sod in December means it sits dormant for 3 months before rooting — and it may not survive a hard freeze with shallow roots.

Xeriscape and native plant beds

October through November is ideal. Xeriscape plants and natives establish fastest when planted before winter. The cooler temperatures, shorter days, and typically increased fall rainfall create perfect rooting conditions. By spring, these plants have developed enough root mass to handle their first summer with minimal supplemental watering.

Patios and hardscape

Patios, walkways, stone work, and retaining walls can be built any time of year. The best months are January through April and October through November — comfortable for crews, no rain delays from summer thunderstorms, and the project is ready for use by the next entertaining season. Summer hardscape work is fine but harder on crews, and concrete cures faster in heat, which can affect finishing time.

Pergolas and outdoor kitchens

Custom steel pergolas and outdoor kitchens require fabrication lead time. The ideal approach: design in summer, fabricate in fall, install in winter. This puts your outdoor living space ready for the first warm weekend in March. If you start the design process in January, installation typically falls in March or April — still great timing.

Landscape lighting

Lighting installation works any time of year. Summer is actually ideal because longer evenings make aiming and adjusting fixtures easier. Lighting does not require water, does not stress during heat, and the installation does not disturb existing plantings significantly.

Fencing

Fence construction works year-round. Austin’s mild winters rarely interrupt fence projects. The busy season is spring (March through May) when most homeowners are thinking about their yards — scheduling in winter often means faster availability.

Irrigation

Install or upgrade irrigation in February or March — before the system is needed. Fall (September through October) is also good for repairs and upgrades. Mid-summer irrigation work is difficult because the system is in constant use and water restrictions limit testing windows.

The Ideal Full-Landscape Timeline

If you are doing a complete landscape renovation — hardscape, planting, irrigation, and lighting — here is the optimal sequence:

PhaseBest MonthsWhat Happens
Design & permittingJune–AugustSite survey, design, permit applications
Demolition & gradingSeptemberRemove old landscape, rough grade
Hardscape constructionOctober–NovemberPatios, walls, edging, drainage
Irrigation installNovemberMain lines, valve boxes, heads/drip
Pergola / structure installNovember–DecemberSteel fabrication + installation
PlantingDecember–JanuaryTrees, shrubs, perennials, groundcover
Lighting installJanuaryPath lights, uplights, accent lighting
Sod & mulchMarchWarm-season sod, mulch all beds
Final adjustmentsAprilIrrigation tuning, lighting aiming, cleanup

This timeline puts planting in the best window (fall/winter), hardscape in comfortable weather, and sod in its ideal spring growth period. Everything is established and looking good by mid-spring.
