Growing Beans

  • Growing Beans

Easy to grow and tasty to eat, beans are a top backyard crop. Part of the legume family, these podded vegies are a good source of vitamins B and C, and fibre.

Fast growers, they provide abundant fresh food for little work, adding colour to the vegie patch when in full flower and laden with pods. 

Late spring is the time to sow seeds for a summer harvest but you can grow beans all year in tropical to subtropical regions and spring to autumn in temperate to cool climates.

Beans are at their most tasty and sweet right after picking, before their natural sugars turn to starch. Harvest pods when young to prevent them getting tough and stringy. 

TIP Beans freeze well and varieties like kidney and haricot can be dried.

French vs runner

Beans are divided into two main types called French and runner. Both have climbing and dwarf bush plants.

FRENCH varieties include snap, string, kidney, haricot, borlotti and more. 

The pods range from long and thin to full and fat in green, yellow, purple and red, and the beans also come in different colours. 

RUNNER or perennial beans grow and produce all summer and autumn then die down in winter when they go dormant, emerging again in spring. 

Most are climbers that feature red flowers and large seeds in green pods. Certain types have white, pink or multicoloured blooms.

TIP Runner beans are hardier than French and better suited to cool areas. 

How to grow                                                                                  

French and runner beans are frost tender, warm-season crops. Don’t grow them where you have raised beans or peas in the last few years.

SOW seeds 50mm deep in moist soil with a pH of 5.5 to 7 in a sunny position sheltered from wind. Dig in well-rotted compost first then make a trench. 

Space dwarf varieties every 200mm in staggered double rows, and climbers 300mm apart. 

Earth up the soil around the stems of dwarf seedlings and give climbers some support.

WATER regularly in hot weather to prevent wilting. Increase water when in flower and the pods begin to swell, making sure the soil never dries out. 

MULCH seedlings by spreading organic matter on top of the soil to retain moisture and promote growth.

HARVEST from eight to 12 weeks when the pods are 170mm or shorter, so they’re young and tender. 

Dwarf varieties crop for a shorter period than climbers.

Picking beans regularly, two or three times a week, encourages new flowers and more vegies.

WATCH FOR slugs and snails, picking them off the leaves of young plants. 

Plants can suffer from fungal diseases like bean rust. If leaves drop, wither or yellow, and brown or red spots appear on the foliage, pods and stems, apply a fungicide. 

TIP To prevent fungal issues, water at ground level, rotate crops and choose disease-resistant varieties.

Harvesting seeds 

Let bean pods hang on a healthy plant for as long as possible before the risk of any autumn frosts then pick and remove the seeds from the pods.

Put them in a paper bag then label and store it in an airtight container in a cool place until planting time next spring.

Choosing a variety 

Grow the beans that you like to eat, choosing a variety to suit your climate and space. Pick dwarf varieties for pots and grow climbers in beds with supports.

How to plant runner beans 

Ideal for small gardens, runner beans take up little room if they’re grown on a tripod or wigwam. Plants tied loosely when they are young will usually climb naturally.

Step 1. Plant seedlings

Plant seedlings in spring every 150mm in double rows spaced about 600mm apart.

Step 2. Make a wigwam

Make a wigwam by tying the tops of bamboo canes with twine to make triangles, adding a ridgepole.

Step 3. Guide the stems

Guide the stems up the canes from inside the wigwam. Water regularly in hot, dry weather.
