When to Plant a Garden in Oklahoma: A Guide for Successful Gardening

Gardening in Oklahoma can be a rewarding experience, but it’s crucial to know the right time to plant your garden. The state’s unique climate and weather conditions require careful consideration when deciding on planting dates. In this comprehensive guide, we will explore the best times to start planting various vegetables, flowers, and herbs in Oklahoma.

The Importance of Timing

Timing is everything when it comes to gardening in Oklahoma. The state experiences diverse climates ranging from humid subtropical to semi-arid zones, making it necessary for gardeners to adapt their planting schedules accordingly. Proper timing ensures that crops have enough time to grow before the extreme summer heat or early frost arrives.

Spring Planting


In late winter or early spring (around February-March), you can get a head start by sowing cool-season vegetables indoors. Crops such as lettuce, broccoli, cauliflower, cabbage, and kale thrive with an early start so they can mature before the scorching summer temperatures.

Note: Ensure you harden off seedlings gradually before transplanting them outdoors by exposing them slowly over several days to direct sunlight and outdoor conditions.

If you prefer direct sowing into your garden beds or containers outdoors without starting seeds indoors first:

– Mid-March through April is ideal for cool-season veggies like peas, radishes, onions (sets), spinach.
– Late April through May is optimal timing for warm-season veggies such as tomatoes*, peppers*, cucumbers*, squash*, corn*, beans*.
(*Consider using transplants instead of seeds unless you are confident about managing longer germination periods.)

Flowers and Herbs

For a vibrant and colorful garden, early spring is the perfect time to sow flower seeds or transplant seedlings. Some popular flowers that thrive in Oklahoma include marigolds, zinnias, petunias, sunflowers, and cosmos. Herbs like basil, parsley, cilantro also appreciate an early start.

Summer Planting
