Cucumber seeds — crisp Cucumis sativus for greenhouse and garden

Few crops are as refreshing as a home-grown cucumber — from long, smooth greenhouse types to ridge and snacking cucumbers for outdoors. They belong to the Cucumis sativus family within our fruiting vegetable range and are close cousins of our gourds and squash. New to growing? Our vegetable growing guide has the basics.

Warmth is everything. Sow once it's warm for fast, trouble-free plants — the calendar shows when.

Greenhouse vs outdoor cucumbers

Smooth greenhouse cucumbers crave warmth and humidity, while tougher ridge and gherkin types thrive outdoors and in our container range. Either way they love to climb, so they pair naturally with other vertical croppers like climbing beans in a small plot.

Growing long, sweet fruit

Train plants up a net or cane to save space and keep the fruit clean — our plant supports guide shows how — and never let them dry out (see the watering guide). Feed once fruiting and watch for powdery mildew in late summer.

Growing under glass? Pick all-female greenhouse varieties for smooth, bitter-free cucumbers.

Frequently Asked Questions

When do I sow cucumbers?
In warmth from mid-spring — they dislike cold, so don't rush them outdoors.

What's the difference between greenhouse and ridge cucumbers?
Greenhouse types are smooth, tender and love warmth and humidity; ridge types are tougher and grow happily outdoors.

Why are my cucumbers bitter?
Usually heat or water stress. Keep them evenly watered, and grow all-female greenhouse varieties to avoid bitterness.

Do cucumbers need support?
They crop best trained up netting or a cane, which saves space and keeps the fruit clean.

What's the white powder on the leaves?
Powdery mildew — improve airflow and water at the roots, not over the foliage.
