How to Grow Cucumbers

Fast, prolific vines that deliver crisp fruit all summer with steady water.

The basics

What cucumbers need

• Sun — Full sun (6+ hours)
• Water — Consistent — 1–2 inches per week; never let them dry out
• Harvest in 50–70 days
• Difficulty — Easy

When to plant

Time it from your frost date

• Start indoors: 3–4 weeks before last frost (optional)
• Transplant: After last frost, handling roots gently
• Direct sow: 1–2 weeks after last frost, once soil is 65°F+
• Best in Zones 4–11

How to plant

Three steps to a strong start

• 1. Direct-sow 1 in deep once soil is reliably 65°F+, or start indoors in pots 3–4 weeks early.
• 2. Provide a trellis or netting — vertical growth saves space and yields cleaner, straighter fruit.
• 3. Keep soil consistently moist; water stress makes fruit bitter.

Common problem

Bitter fruit

Caused by water stress and heat — keep moisture steady and harvest young.

Common problem

Powdery mildew

Improve airflow, water at the base, and choose resistant varieties.

Harvest

Picking cucumbers right

Pick daily once fruiting starts — slicing types at 6–8 in, picklers at 2–4 in. Over-ripe fruit turns yellow and bitter and shuts down the vine.

Gardeners ask

Do cucumbers need a trellis?

Not required, but trellising saves space, improves airflow, and gives straighter, cleaner fruit.
