When to plant cucumbers in Texas

Plant spring cucumbers about 1–6 weeks after the local frost-free date, once cold risk and cold soil have passed. For fall, count back 10–12 weeks from the first freeze; regional averages run from July 15 in Region I to October 1 in Region V.

Spring and fall are different calculations

Start with your local frost date

Texas is too large for one planting day. Spring timing is measured from the local average frost-free date. Fall timing is measured backward from the local first freeze, then checked against the Texas A&M regional anchor when one is published.

Spring rule

1–6 weeks after the local frost-free date

Use the frost-free date for your garden, not a statewide average.

Fall rule

10–12 weeks before the first freeze

Count backward from the local first freeze and leave room for establishment.

West Texas and the High Plains

Region III

Plant only when the crop is ready

The calendar is the first filter

A date can be inside the planning range and still be a poor planting day. Check the crop-specific conditions before committing seed or plants.

  • Cold nights are no longer threatening a warm-season seedling.
  • The soil is warm and drains after irrigation or rain.
  • A fall crop can finish before the first killing freeze.

How to start cucumbers

Direct sow avoids root disturbance. A small transplant can shorten the schedule if its root ball stays intact.

Wait beyond the frost date

Frost-free does not automatically mean warm enough; use the forecast and soil condition before sowing.

Protect the roots

If using a transplant, move it young and keep the root ball intact.

Check the fall runway

Count the variety’s maturity time plus establishment days before the local first freeze.

When the simple answer breaks

Early and late decisions

A usable planting page needs an action when weather, region or maturity no longer fits the headline range.

Cool wet spring

Wait rather than resow

Cold, saturated soil can erase the advantage of an early date and lead to poor emergence.

Late summer planting

Use the regional anchor and freeze countback

The average date alone does not prove that a long-maturity cultivar will finish.

Why this answer is shaped this way

Spring and fall fail for opposite reasons

Spring cucumber planting is limited by cold soil and nights. Fall planting is limited by the shrinking warm-season runway. The page keeps those two failure modes separate.
