San Antonio Vegetable Planting Calendar
Use San Antonio climate patterns to see this month’s garden tasks and crop-by-crop planting windows for the warm south-central Texas transition between the Hill Country and Blackland Prairie.
Plant through winter
Broccoli, lettuce, peas, carrots, radishes and leafy greens perform best from fall through early spring.
Use spring warmth
Plant tomatoes, beans, cucumbers, squash, okra and peppers early, then plan a second warm-season window before fall cool crops.
Restart the cool garden
Begin fall brassicas indoors and prepare beds for direct-sown roots and greens as temperatures moderate.

How to Read This Calendar
Start indoors
Sow in trays under strong light. The window is timed so seedlings reach transplant size without becoming root-bound.
Transplant or plant
Harden seedlings off for about a week. Perennial crowns, sets and seed potatoes are included in this column.
Direct sow
Plant seed directly into prepared soil. Cool-season crops can begin before frost; heat-loving crops need warm soil.
Last planting
This is the practical end of the selected window—not a guarantee. Variety maturity and unusual weather can move it.
Keep soil working after harvest
Fall Cover Crop Planting Calendar
These windows are calculated from this city’s approximate first fall frost. Sow into an open bed after harvesting vegetables, then follow the selected crop’s product directions.
| Cover crop | Best for | Approx. planting window | Winter behavior |
|---|---|---|---|
| Buckwheat | Quick biomass · pollinators | Sep 20–Oct 4 | Frost-killed |
| Oats | Biomass · nutrient capture | Sep 20–Oct 18 | Usually winter-killed |
| Field Peas | Nitrogen · cool-season growth | Sep 20–Oct 18 | Often winter-killed |
| Daikon Radish | Compaction · nutrient capture | Sep 20–Oct 18 | Usually winter-killed |
| Crimson Clover | Nitrogen · pollinators | Oct 4–Oct 18 | Overwinters where adapted |
| Annual Ryegrass | Roots · erosion control | Oct 4–Nov 1 | Manage before seed set |
| Hairy Vetch | Nitrogen · spring biomass | Oct 18–Nov 1 | Overwinters in many areas |
| Cereal Rye | Erosion · weeds · biomass | Oct 18–Nov 15 | Very winter-hardy |
| Winter Wheat | Erosion · nutrient capture | Oct 18–Nov 15 | Winter-hardy |
Planting windows are planning estimates. Check the product page for seeding rate, regional adaptation, inoculation needs, and termination timing.

Let Soil Temperature Be the Final Check
Calendar dates start the conversation. A simple soil thermometer helps confirm that the seedbed is actually ready.
