When to plant lettuce in Texas

Spring lettuce can be planted from about 6 weeks before to 2 weeks after the local frost-free date, provided heat is not arriving too fast. For fall, count back 10–14 weeks from the first freeze; regional averages run from September 1 in Region I to December 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

6 weeks before to 2 weeks after frost-free

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

Fall rule

10–14 weeks before the first freeze

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

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.

  • The crop can establish outside peak heat.
  • The bed can stay evenly moist without remaining waterlogged.
  • The lettuce type and maturity time fit the cool-weather window.

How to start lettuce

Direct seed works in a fine, cool bed; transplants shorten establishment when the mild-weather window is narrow.

Choose the lettuce type

Leaf, butterhead, romaine and crisphead do not share one maturity timeline.

Keep seed shallow and moist

Direct seed only where the surface can be protected from drying during emergence.

Use transplants selectively

A compact, hardened transplant can save time when the seasonal window is short.

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.

Early fall remains hot

Wait for establishment weather

The regional date is not permission to germinate lettuce in damaging heat.

Spring heat is accelerating

Use a faster type or stop

A late planting that immediately runs into heat may never deliver the intended crop.

Why this answer is shaped this way

The wide spring rule needs a heat check

The frost-relative range is deliberately broad. Lettuce is often limited by heat before frost becomes the main problem, so the current forecast remains part of the answer.
