When to Plant in Oklahoma

Oklahoma gardeners deal with a dynamic climate that can bring everything from intense heat to sudden cold snaps. The state's long growing season is excellent for a wide variety of crops, provided you can navigate the volatile spring weather.

Success in the Sooner State involves working with the elements. Managing the wind, providing consistent water during hot spells, and taking advantage of the long fall are the keys to a productive Oklahoma garden.

Planting tomatoes too late — getting fruit to set before the July heat arrives is the biggest challenge.
Underestimating the fall season — Oklahoma has a fantastic second season for cool-weather crops in autumn.
Neglecting soil health — many Oklahoma soils benefit from organic matter to improve moisture retention.
