Okra

Insect-pollinated okra needs at least ¼ to 1 mile for safe distance isolation. Time isolation is practical for growing two varieties in one season, since okra is a long-season plant (it may be commonly grown in your area, however, so don't forget the neighbors). Save seed from the early planting before the late one starts to flower... to safely save seed from the later planting, you might at some point have to pull the early planting, or prevent their flowers from opening and crossing the later planting.

Caging can also be used, but large cages would be needed as plants can be fairly tall (plants planted later in the season would flower before getting as tall as earlier-planted ones).

Allow pods to dry on the plants until they begin cracking, then split open to remove seeds and finish drying. Okra produces a high percentage of 'hard seed' (seeds with seed coats which are not readily permeable to water) and can be slow to germinate after thorough drying or long storage. For best germination, soak okra seeds overnight before planting to give hard seeds time to imbibe water.

Okra seeds can be stored for up to 4 years.
