If you live in a place with hot summers and mild winters, it's easiest to plant okra in your garden patch, rather than starting it indoors. You'll want to plant the okra seeds in early spring, after the last frost of the year, when the temperature doesn't dip below 55 degrees at night. If that doesn't happen until late spring or early summer where you live, then it's better to start your seeds indoors 2-3 weeks before the last frost. When the seedlings are sturdy and the weather warms up, you'll transplant them to your garden patch.  To start seeds inside, plant the seeds in peat seed starter and keep them well-watered. Put them in a warm, sunny room or use grow lamps to keep them warm during the germination period. Keep the temperature between 65 and 70 degrees Fahrenheit. When the weather warms up and you're ready to transplant the seedlings, follow the same steps you'd use to grow okra from seed outdoors. Okra grows best in full, hot sun. If you try to grow it in a shady spot, it won't produce much fruit, if it lives at all. Okra should be planted in a location that gets at least 6 hours of full sun every day. Don't worry that it'll get too hot - okra really gets going at summer's peak, when the sun beats down on the garden at its hottest. Okra grows best in a soil with a pH level between 6.5 and 7.0.  test your soil's pH level to determine whether it is in the proper pH range. You can work in limestone or bone meal to increase the soil's pH. If you'd prefer not to change the pH level of your soil using any drastic measures, you can simply work in plenty of compost, which will drive the pH towards neutral, or 7. Okra grows well in very rich soil that's packed with nutrients. You can enrich your soil using compost, bagged organic fertilizer, or 4-6-6 slow release fertilizer. Either way, till the soil to a depth of 12 inches (30.5 cm) and work in 4 inches (10.2 cm) of compost or fertilizer using a garden rake so that it's evenly distributed. Neglecting to add nutrients to the soil may result in okra plants...
