How to grow beans in a raised bed

Beans are one of the easiest, most generous crops going, and climbing beans make brilliant use of a raised bed's height. As legumes, they even feed the soil.

Quick facts

• Position: full sun, 6+ hours
• Spacing: 10–15 cm apart
• Tub depth: our 35 cm depth
• Time to harvest: 8–11 weeks
• Support: a trellis for climbing types

When should I plant beans?

Beans are frost-tender — plant from spring through summer. Sow directly where they're to grow, as they don't love being transplanted. Our free garden calendar shows the right months for your postcode.

• Subtropical (Brisbane & SEQ): August to March
• Temperate (Sydney, Melbourne, Adelaide, Perth): September to January
• Cool & mountain (Tasmania, Canberra, highlands): October to December
• Tropical (Cairns, Darwin): March to August
• Arid inland: February to March and September to November

How do I grow beans in a raised bed?

Sow seed straight into warm mix. Give climbing beans a trellis to run up; bush beans need no support. Don't over-feed with nitrogen — beans make their own.

How often should I water and feed beans?

Keep the mix evenly moist, especially once flowering and podding — dry spells mean fewer pods. Water the soil in the morning.

What pests attack beans?

Keep an eye out for aphids, caterpillars, two-spotted mite and the 28-spotted ladybird. Most are easily managed — see our safe pest guide.

What diseases affect beans?

The main ones are rust, mosaic virus and downy mildew. Good airflow, morning watering and steady moisture prevent most.

What grows well with beans?

Carrots, cucumber and corn are good neighbours; keep beans away from onions and garlic. See our companion planting guide.

When do I harvest beans?

Pick pods young and often while they snap cleanly — regular picking keeps the plant cropping for weeks.
