Okra

A warm-climate crop that needs a long, hot season. In the UK it performs best in a greenhouse or polytunnel. Start early, keep it consistently warm, and you'll be rewarded with tender pods from midsummer right through to the first frost.

Sowing Guide

What you'd find on the seed packet

Sow Depth

1cm

Spacing

45–60cm

Germination

7–14days at 20–25°C

Thinning

One plant per large pot: pot on individually rather than thinning to avoid disturbing the roots

Grower's Note

Soak seeds overnight before sowing to improve germination. In the UK, okra needs consistent warmth above 20°C to thrive: a heated greenhouse gives by far the best results.

Recommended Varieties

'Clemson's Spineless' is the long-standing standard UK variety, spineless pods that are genuinely easier to prepare. 'Pure Luck' F1 matures earlier with thinner, smoother pods, worth it given how short and unreliable the UK's warm growing window is for okra. Neither holds an RHS AGM, and okra remains a marginal UK crop even with an RHS grow-your-own guide now available.

Planting Out Guide

Best spaces, conditions and how to plant out

Plant Spacing

45–60cm

Best Grown In

Greenhouse borders, large containers, grow bags

Conditions

Full sun, warm. Rich, free-draining compost. Heat-loving: greenhouse cultivation gives significantly better results in the UK.

Grower's Note

Harvest pods at 5–8cm when still tender. Once they toughen they become woody. Check plants every 2–3 days at peak production.

Watch Out For

Cold temperatures below 15°C check growth severely: keep in a greenhouse or the warmest possible spot; do not move outside without reliable sustained warmth

Aphids and whitefly colonise indoor plants: introduce biological controls early or spray with a dilute soap solution weekly before an infestation builds up

Pods pass quickly from tender to tough: harvest at 7–10cm within a few days of the flower opening, sooner in hot weather, which speeds ripening. A pod left too long turns dry and fibrous with hardened, dark seeds inside: the same stage used for saving seed, not a sign anything has gone wrong, just past its best for eating.

Common Questions

About growing Okra in the UK

Can okra be grown successfully in the UK?

Yes, but it requires heat. In a greenhouse or polytunnel, okra crops reliably. Outside, it is possible in a warm summer in the south of England but yield will be much lower. Start seeds in a heated propagator in April and grow on in the warmest spot available.

How do I harvest okra?

Harvest pods at 5–8cm long, when still tender. At this stage they snap cleanly. Pods left on the plant become woody and fibrous within days. Check plants every 2–3 days at peak production. Regular harvesting encourages continued flowering and fruiting.

Why is okra slimy when cooked?

Okra contains mucilage, a natural thickening agent that is released when cut or cooked in water. To reduce sliminess: cook at high heat in a dry pan or on a grill, add acid (vinegar or lemon juice) to the dish, or use whole pods in curries and stews.

What temperature does okra need to germinate?

Okra seeds need soil temperatures of at least 20°C to germinate reliably: ideally 25–30°C. A heated propagator is strongly recommended for UK growing. Soaking seeds overnight before sowing can also improve germination rates.
