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.
Cut and come back. About 8 weeks after planting the okra, the pods will start to grow. Once you see the first okra pods emerge and mature, you can start regularly harvesting them. Use a scissors or a hand pruner to cut the okra pods just above their caps, where their thick stems meet the branches of the plant.eep harvesting the okra throughout the summer until the growing season slows and the plants stop producing new pods. 1  Harvest the pods when they are 2 to 3 inches (5.1 to 7.6 cm) long. 2  Harvest the okra every other day, and every day during the peak of the season, to encourage fast regrowth.
