How to Grow

Cultivation

Grow outdoors from late spring to October, in bright but indirect light, gradually acclimatising to full sun. The plant prefers growing in a well-drained acidic compost, consisting of a mix of equal parts ericaceous, peat-free compost, perlite and vermiculite. Water the plant when the top inch of the compost has become dry, avoiding wetting the leaves, or keeping the compost consistently wet, which can cause rot. Use rainwater, or filtered water, such as reverse osmosis water, rather than tap water, which in hard water areas is alkaline, and if used for acidic soil loving plants, can lead to nutrient disorders. Fertilise once a month during the growing season, April to September, with a dilute liquid feed that is high in potassium. See begonias: outdoors, for further information
