How to Grow Okra – The Requirements


Okra requires sufficient water especially during the warm months of summer. Okra does only requires about an inch of water weekly. You can water it at the same time as other plants. Simply concentrate at the base and water gently so as not to wash the soil off. Do not water the leaves of the plants because it can be a breeding spot for fungi. It is an excellent plan to water in early in the morning, that way the afternoon sunlight will dry any leftover water that was not absorbed.


Ideal soil requirements are fertile and well-drained with near-neutral pH. The soil pH should range between 6.5 and 7.0, though, the plant can tolerate soils with a pH of 7.6. The soil should be warmed between 65° to 70°F. It must be in rich, well-drained soil with sufficient light.


Okra thrives in full sunshine or partial shade so they are ideal for growing in greenhouse kits. It simply won’t bear plentiful seed pods without abundant sunlight. It weakens and becomes exposed to bugs and diseases if it is too cold or s, even for a quick period of time.


Okra matures about two months after planting. Harvest the pods when they are about 3 inches long by cutting their stems just above the cap. If the stalk is so difficult to cut, the pod is presumably too old and should be thrown away. You can pick it every other day. Be sure to wear gloves or long sleeves because the tiny spines may irritate your skin. You can have as much as you want because when you harvest a pod, another one sprouts in its place.


To store okra, blanch it for three minutes, soak it into an ice bath to prevent it from overcooking, then slice it into bite-sized portions. Place the uncut and raw pods inside freezer bags and put them in the freezer. Try canning or you can then prepare it in any way you want.

A little bit of okra can go a long way. You can also check out more plants on our ‘How to Grow’ Collection.
