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.
Choose your sunniest spot for growing okra, and wait until the weather is warm to set out your plants. Plants like it when nights are at least in the 60s and days 85 or warmer. In the North, gardeners might wait until late June to plant, since pods appear within 2 months. Okra grows best in soil with a near-neutral pH between 6.5 and 7.0, although it will do fine in a pH as high as 7.6.
