OSU Extension describes fall as a strong Oklahoma vegetable season when warm sunny days can be followed by cool humid nights.
Successful fall gardening starts before fall because seeds and transplants may go into the garden during June, July, August, and September.
July and August plantings need supplemental irrigation because hot soil, intense light, and rapid drying can prevent uniform seedling stands.
