Prior to planting, soak the okra seeds in water for 12 to 18 hours to soften its hard seed coat. Soaking aids moisture absorption and germination. Plant okra in the spring or early summer once the threat of frost has passed.hoose a garden spot where its shade will not harm other sun loving plants. Sow the seeds one inch deep in rows that are three feet apart. The seeds generally germinate in two to 12 days. Okra will grow in many soil types, so mulch and fertilize as needed.
Okra reaches maturity in 50 to 65 days. The plants can produce for ten to 12 weeks. It grows and bears seed pods until frost, which quickly turns them black and kills them. Start harvesting a few days after the okra blooms fade. At that point the seed pods should be soft and two to three inches long. Pick the pods at least every other day, as they quickly turn from tender to tough the bigger they grow. Handle okra gently.
