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.
Sow the seeds or plant the seedlings. When the weather is warm, it's time to plant the okra in your garden. Sow your seeds 4 inches (10.2 cm) apart at a depth of 1â2 inch (1.3 cm). If you started your seeds indoors, handle the seedlings very carefully and plant them 1 foot (0.3 m) apart in rows 3 feet (0.9 m) apart.
