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.
Like Larry said, okra seed has to be fresh to germinate. I had a chart once that told how long garden seeds remain viable and okra was at the top of the list with only a one year reliable germination rate. I keep my seed in the freezer and it will keep for 2-3 years, maybe longer. Like Bookmark May 10, 2013 at 3:39PM.
