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.
A cold snap in early spring can kill okra blossoms. Whether adding okra (Abelmoschus esculentus) to your garden for its edible pods or simply its ornamental value, you must protect the delicate plant from cold temperatures. Okra is an annual plant that thrives during the warm spring and summer season and grows 3 to 6 feet tall. Pick pods while they are immature at 2 to 3 inches long. Okra plants will present a prolific harvest through the first frost in the fall.
