When to plant Bean (Climbing) in Temperate Australia

Temperate zone — applies to Sydney, Melbourne, Adelaide, Perth, Newcastle and similar areas. Growing elsewhere? Cool · Subtropical · Tropical · Arid.

From September to January, sow climbing beans direct at the base of a sturdy trellis in temperate Australia — this is a warm-season crop with no tolerance for frost. Seed sown 20–30 mm deep germinates in 7 to 15 days, and the first pods arrive in 70 to 85 days, a few weeks behind bush types but with a far longer picking season from much less ground. Allow 10–25 cm between plants and put the support up before you sow, not after; a two-metre frame is not too tall for these vines.

Growing notes

Climbing beans are frost tender, and in temperate Australia the mid-October last frost defines the real start of the season. September sowings only make sense in warm, sheltered gardens; for most plots October and November are the reliable months. The window closes in January for good reason — pods take 70 to 85 days, and sow much later than that and the first frosts around May arrive before the harvest amounts to anything.

The trellis is half the crop. Vines twine up whatever they can reach and easily pass two metres; string, mesh or tepees all work, but the structure must carry real weight and stand up to summer wind. Build it first, then sow 20–30 mm deep along its base, allowing about a metre between rows.

Warm, free-draining soil with compost is all they need — like every legume they fix their own nitrogen, and heavy feeding produces a wall of leaves with few beans. Water deeply at flowering and podding; moisture stress at that stage is the main reason flowers drop without setting.

The other frequent failure is simple neglect at picking time. Pods hidden in the foliage grow tough and stringy, and every mature pod left hanging tells the vine to wind down. Pick every second day at the height of the season and the plants keep producing until the weather turns.

Common questions

When do you plant climbing beans in temperate Australia?

Sow direct from September to January, though October and November are safest — climbing beans are frost tender and the last frost usually lands around mid-October.

How tall do climbing beans grow?

Two metres or more. Put a strong trellis, mesh or tepee in place before sowing, because the vines need support from their first weeks and the structure has to carry serious weight.

Why are my climbing beans flowering but not setting pods?

Flower drop is usually heat or moisture stress. Water deeply and consistently from flowering onward, and expect pod set to improve as extreme heat passes.

Are climbing beans better than bush beans?

They take longer — 70 to 85 days against 50 to 80 for bush types — but crop over a much longer period and yield more from the same ground, provided you keep picking.
