Runner bean 'Armstrong'

Armstrong likes a position of full sun and remember to water moderately. Keep in mind when planting that Armstrong is thought of as tender, so remember to ensure that temperatures are mild before moving outdoors. Ideally plant in loamy and clay soil and try to keep the ph of your soil between the range of 6.0 and 6.8 as Armstrong likes to be in weakly acidic soil.

Aim to sow 1.95 inches (5.0 cm) deep and try to ensure a gap of at least 3.9 inches (10.0 cm). Soil temperature should be kept higher than 16°C / 61°F to ensure good germination.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Armstrong is a tender plant.
