>>>On average Henry says okra plants grow to about 5 or 6 feet. <<<
That depends on the okra species. Certain species grow much taller than others. There are other factors. For example, okra loves heat. If you plant too early in the spring the growth will be stunted. Another critical factor is water. Mulch will enhance growth by providing additional heat, plus the added moisture okra desires. But water is key. I watered every four days (or the fourth day after a good rain), and routinely grew 16 foot okra plants in my South Carolina garden. I am certain many plants were more than 17 feet.
Do you direct seed or start plants indoors?
Philip, I agree with you, it seems like my family garden had Okra that was large also. My dad is has a garden evey year, even at age 85. Love those fresh South Georgia veggies from my daddy's garden.
