Pelargonium 'Black Knight' Lea (Dw/d/C)

Will grow well in a frost-free environment, in well-drained fertile neutral to alkaline soil, preferably in full sun but will tolerate some partial shade, in borders or containers. Irrigate moderately from spring to summer, and sparingly in winter allowing the compost to dry up between waterings. Apply a balanced liquid fertilizer during the growing season and switch to a high potassium fertilizer when flowering starts. Overwinter in containers before the first frost in autumn. See Pelargonium cultivation for further advice.

Pinch back tips of shoots in spring or early summer and deadhead to promote flowering. If overwintering, cut back hard in autumn or spring.

Propagate by seed in late winter and from softwood cuttings from spring to autumn.

May be susceptible to Thrips, vine weevil, Leafhopper, Root mealybug, Whitefly.

May be susceptible to Pelargonium rust, Pelargonium viruses, Leafy gall.
