As the seedlings reach a height of about 6 to 8cm, remove all extra seedlings and leave a bush bean plant every 10 to 15cm, or one to two bean vines growing up each pole if using the trellis system. Densely planted bush beans are less prone to be knocked over by wind or rain, as they support each other.
Only after blooming and the bean pods have set should you put down a very light sprinkling of a balanced fertiliser
. Fertilising earlier will delay flowering.
to suppress weeds and to slow evaporation. Water
beans regularly in the absence of rain. During bloom time it is crucial to keep the soil moist but not soggy. Water preferably at the base of the plant in order to keep the leaves dry. Wet leaves, especially overnight, can encourage diseases.
Blossoms but no beans
Heat stress can cause beans to stop developing bean pods although they have bloomed before. Once the hot weather subsides, they will continue to produce, provided they receive sufficient moisture.
