Pelargonium crispum is ideal for any garden as it flowers for most of the year and can withstand extreme temperatures.

It can be grown from seed and cuttings. Sow seeds in autumn. Fill seed trays with a light, well-drained potting soil. Spread the seeds evenly on top of the soil. Cover seeds with a thin layer of white sand. Water thoroughly with watering can with a fine spray. Place trays in a lightly shaded area. Germination usually takes place within 4 weeks. Pelargoniums grown from seed are generally more vigorous than those grown from cuttings. Transplant seedlings into the garden or in pots. The plant can grow easily in a garden with damp to moist soils in full sun.

Cuttings can be grown at any time of the year. Take young stem cuttings 150 mm long and apply a rooting hormone to stimulate the rooting process. Insert them into prepared holes and place in a cold frame to root. Rooting usually takes about 3-4 weeks. Once the cuttings have rooted, pot them in a well-drained potting soil mix. Feed the newly rooted cuttings with a liquid seaweed-based fertilizer.
