Climbing beans are warm-season legumes that produce heavily over a long season when given a suitable support structure. They include common pole beans (P. vulgaris) and scarlet runner beans (P. coccineus). Runner beans tolerate cooler conditions than common beans. Both fix atmospheric nitrogen via Rhizobium bacteria in root nodules, improving soil fertility.

How to Grow Climbing Beans in Mediterranean Australia

When to Plant

Sow October-January. Perth and Adelaide have excellent conditions for climbing beans. Hot, dry summers suit beans well if watered.

Soil
Well-drained, fertile loam enriched with compost. Avoid freshly manured soil (excess nitrogen causes leaf growth at expense of pods).
pH Range
6.0-7.0
Sunlight
Full sun (minimum 6 hours, preferably 8 hours)
Spacing
15cm apart, 80cm between rows
Watering
Regular deep watering during flowering and pod set is critical. Inconsistent watering causes flower drop and tough, stringy pods. Water at base, avoid wetting foliage.

Companion plants: Corn, Squash, Marigold, Radish, Carrot

Avoid planting near: Onions, Garlic, Fennel, Beetroot

Harvesting Climbing Beans

When ready: Green beans: pods snap crisply when bent, seeds inside are small and immature, pod surface is smooth (not lumpy from enlarged seeds). Shell/dry beans: leave on vine until pods are brown and papery, seeds rattle when shaken.

How to harvest: Hold the stem with one hand and pull the pod with the other to avoid breaking branches. Use scissors for tough stems. Harvest green beans every 2-3 days. For dry beans, cut entire vine and hang upside down to finish drying.
