Yes, that is right, I said Fall when the Summer season just begun!
There are actually two seasons to plant a garden in NE Oklahoma, Early Spring and Mid-Summer. Aren’t we lucky? Each season requires some adjusting watering, cover, etc. but gardening in Oklahoma takes adjusting to the weather, period!
Oklahoma State University Cooperative Extension has an excellent fact sheet on Fall Gardening.
Here is a list of tender and semi-hardy vegetables with planting times.
