When to Plant Lettuce in Tyler County, TX

Lettuce

Lettuce is a fast-growing cool-season green available in leaf, romaine, butterhead, and crisphead types. It is the foundation of salads and one of the easiest crops to grow.

Tyler County, Texas is in USDA Zone 9a. The average last spring frost is March 6 and the first fall frost is November 19, giving you a growing season of approximately 258 days.

Summer highs average 95°F, so Lettuce may need afternoon shade and extra watering during peak heat.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Lettuce root diseases.
