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.
Month-by-Month Calendar
| Month | Planting | Hardscape | Rating |
|---|---|---|---|
| January | Trees & bare-root roses | Excellent — mild weather | Good |
| February | Trees, shrubs, cool-season color | Excellent | Good |
| March | Everything — best spring window opens | Excellent | Best |
| April | Perennials, natives, warm-season turf | Great | Best |
| May | Last call — heat arriving | Good (getting hot) | OK |
| June | Avoid planting | Good for construction crews | Hardscape only |
| July | Avoid planting | Hardscape + lighting | Hardscape only |
| August | Avoid planting | Hardscape + steel fabrication | Hardscape only |
| September | Fall window opens mid-month | Excellent | Good |
| October | Best planting month of the year | Excellent | Best |
| November | Trees, shrubs, bulbs | Excellent | Best |
| December | Trees (dormant planting) | Good (holiday scheduling) | Good |
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 Type | Best Install Window | Avoid |
|---|---|---|
| Bermuda | March–May (spring growth) | November–February (dormant) |
| St. Augustine | March–April or Sept–Oct | June–August (heat stress) |
| Zoysia | March–May | November–February |
| Buffalo grass | March–May | November–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:
| Phase | Best Months | What Happens |
|---|---|---|
| Design & permitting | June–August | Site survey, design, permit applications |
| Demolition & grading | September | Remove old landscape, rough grade |
| Hardscape construction | October–November | Patios, walls, edging, drainage |
| Irrigation install | November | Main lines, valve boxes, heads/drip |
| Pergola / structure install | November–December | Steel fabrication + installation |
| Planting | December–January | Trees, shrubs, perennials, groundcover |
| Lighting install | January | Path lights, uplights, accent lighting |
| Sod & mulch | March | Warm-season sod, mulch all beds |
| Final adjustments | April | Irrigation 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.
What to Do Right Now
No matter what month you are reading this, there is something productive you can do:
- Summer (June–August): Design and plan. Build hardscape. Install lighting. Do not plant
- Fall (September–November): Plant everything. Continue hardscape. Best overall window
- Winter (December–February): Plant trees. Build structures. Prepare beds for spring
- Spring (March–May): Install sod. Plant remaining perennials. Finish and enjoy
