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.
Step 3. Keep the soil around the okra seeds from drying out while the seeds germinate. Water when the soil begins to dry, but do not provide water to create puddles around the seeds.
