  • Failure of fruit to set can be due to lack of bees so hand-pollinate by picking the male flowers, breaking them away from the petals then dusting the centre stamens over the stigma or centre of the female flowers. Pollination is best carried out early in the cool of the day. Some plants produce a succession of up to 10 male or female flowers and pollination is less of a problem when you have a number of plants. Shriveling of embryo fruit due to mildew can be controlled by adding 1 tablespoon of sulphate of potash per sq. m of soil around the plants when flowering commences and watering in.
