Propagation of Pelargonium peltatum is very easy. The plant can either be grown by cuttings or seed.

Cuttings can be taken in spring and autumn or after the flowering or seeding period. Semi-mature stem cuttings can be taken from young healthy growth. The rooting hormone for softwood or semi-mature wood is used to help with the rooting process. The cuttings are placed in a propagation tray and placed in a cold frame to root. Rooting of this species takes place within 4 weeks. Once they are well rooted they can then be potted in a well-drained soil mix.

Seed can be sown in a well-drained soil mix. Seed should be sown to a depth of 2-3 mm in late autumn. Germination should occur 3-4 weeks after sowing.

Both the cuttings and seedlings should be fed with an organic-based fertilizer. Fungal infections may occur during and after periods of damp or wet weather. Spray with an appropriate fungicide if there are any signs of mildew or rust. Tiny caterpillars eat out the centre of the flower buds and appropriate measures should be taken to control themThis plant can be used in many ways. Plant it alongside trees or a trellis, encouraging it to scramble up. Or plant it to cascade down terraced or retaining walls. It is also excellent as a container plant for hanging baskets, window boxes and planter troughs. The plant does well in shade and full sun, although it flowers more profusely in full sun. It also makes an excellent groundcover under larger trees. . Dead flowers must be pinched off to promote more flowering and maintain a neat and tidy plant. In autumn, long and leggy stems should be cut back to the point where healthy green leaves remain on the plant. This pruning will allow your plant to grow and flower profusely.
