Start with the geography
Texas regional model
Texas A&M uses five gardening regions. A North Panhandle planting plan cannot be transferred to the Lower Rio Grande Valley. Use the relevant regional anchor when it is published, then check it against the local first-freeze date.
Then test the crop
Count the growing runway
For each crop, count backward from the local first freeze using its maturity period and leave an establishment margin. A regional average makes the choice practical; the freeze countback tests whether the particular variety still fits.
What to do before planting
- Choose the Texas gardening region before narrowing the crop list.
- Prefer a shorter-maturity crop or transplant when the remaining window is tight.
- Prepare for hot, dry late-summer establishment with drainage, moisture and an appropriate forecast.
Common false moves
What not to simplify away
- Do not use one Texas date across five very different regions.
- Do not confuse a regional average with a county boundary or exact-day guarantee.
- Do not start a long-maturity crop merely because late summer still feels warm.
