pelargonium 'Cardinalis'

Grow in fertile well-drained soil in full sun or partial shade. Remove spent flowers. To overwinter, grow small plants in late summer from cuttings or cut back old plants by one third and lift for storage in frost-free place to repot in spring when growth resumes. See Pelargonium cultivation for further advice.

Deadhead regularly

Take softwood cuttings in summer and overwinter plants in frost free conditions or take softwood cuttings in spring

vine weevil, leafhoppers, caterpillars, thrips, fungus gnats and Aphids can be troublesome. Aphids are generally more problematic on over-wintered plants

Foot and root rots can be a problem in wet soils. Grey moulds are often troublesome in wet conditions. A virus can often be a problem where cultivars are maintained by cuttings. Pelargonium rust can be damaging to zonal pelargoniums and associated hybrids
