1 You can also start okra directly in your garden 3 to 4 weeks before the last spring frost date as long as you cover the plants with a cold frame or grow tunnel until the weather warms up. Make sure that the covering is 2 to 3 feet tall so that the plants have room to grow. You can soak the seeds overnight in tepid water to help speed up germination. 2  If you are planting okra transplants, be sure to space them 1 to 2 feet apart to give them ample room to grow. 3  Okra plants are tall, so be sure to space out the rows 3 to 4 feet apart.
If buying okra plants, purchase those that are started in containers such as peat pots that can go into the ground. Disturbing okra's roots hampers growth. Okra can grow from three to six feet tall. Choose a garden spot where its shade will not harm other sun loving plants.
