Runner bean

How to plant it

General steps for this plant. Save a garden and these become specific to your location, soil and light.

1. Step 1When to plant

   Plant during March to May, once the risk of frost has passed.

   Timing depends on your last frost date.

2. Step 2Where to put it

   Choose a position in full sun for most of the day. Allow 0.5 m of room around it — mature spread is 0.5 m and mature height 2–2.5 m.

   Light in your garden is not answered, so this is the plant's own requirement.

3. Step 3Preparing the ground

   Dig a hole twice as wide as the root ball and no deeper, loosen the sides, and plant so the top of the root ball is level with the surrounding soil.

   Soil is not answered. This plant grows in average, moisture-retentive conditions.

4. Step 4Watering while it establishes

   Water thoroughly at planting (5–10 litres), then only when the top few centimetres of soil are dry, through the first growing season.

   Even a drought-tolerant plant (2/5 here) only becomes drought-tolerant once established.

5. Step 5Mulch

   Spread 5–7 cm of composted bark or garden compost around the plant, keeping it clear of the stem.

   Mulch cuts water loss and suppresses weeds through the first summer, when losses are most likely.

6. Step 6The first year

   Check watering weekly in summer, remove competing weeds, and tidy dead growth at the end of the season.

   Maintenance level on the plant record is medium.

7. Step 7What to watch for

   Flowers drop in extreme heat and drought. Toxicity: mild. Site it accordingly if children or pets use the space.

Spacing: about 0.5 m apart — roughly 40 plants for every 10 m² if planted as a group.
