How to grow Runner bean 'Black'
Black likes a position of full sun and remember to water moderately. Keep in mind when planting that Black is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Planting Black in loamy and clay soil with a ph of between 6.0 and 6.8 is ideal for as it does best in weakly acidic soil.
Growing Black from seed
Try to aim for a seed spacing of at least 3.9 inches (10.0 cm) and sow at a depth of around 1.95 inches (5.0 cm). Soil temperature should be kept higher than 16°C / 61°F to ensure good germination.
Transplanting Black
As Black is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
