pelargonium 'The Boar'

Under glass grow in a loamless, or well drained, loam based compost (JI No 2) in full light but with protection from hot sun. Water moderately when the plant is in active growth and feed with a balanced fertiliser in spring, switching to a high potash fertiliser from early summer until autumn. Outside, grow in a neutral to alkaline soil in full sun. Lift in the autumn and keep plants dry, in bright light and frost free conditions until the spring. See Pelargonium cultivation for further advice.

Cut back top growth by up to two thirds and repot overwintering plants as they are resuming new growth in the late winter/early spring

Take softwood cuttings in spring, late summer or early autumn
