Pelargonium scabroide can be propagated from cuttings and seed. Cuttings can be taken at any time of the year from healthy vigorous plants, from softwood or herbaceous growth, preferably after the flowering and seeding period. Using a rooting hormone will speed up the rooting process, especially for the softwood cuttings. Place the cuttings in river sand in cold frames and keep them moist. The cuttings should root within 4 weeks. Give the rooted cuttings a 2-week weaning period and transplant them into a well-drained potting soil mix and place them in a sunny position. Once the plants have formed a strong root ball they can be planted out into the garden section you have specially prepared for them to be displayed and enjoyed by others.

Sow seeds in late summer to early autumn. The seeds should be sown in a light, well-drained potting mix. Sprinkle the seeds evenly in the seed tray and cover them with fine-milled pine bark. Water the seeds gently but thoroughly with a fine-nozzled watering can and place them in light shade with no direct sun. Seed germinates within 3 weeks. Plants grown from seeds will flower within 12 to 18 months. Pelargoniums grow very well outdoors, free of any diseases, but if the same plant is grown indoors or in a greenhouse the warmer climatic conditions and lack of air circulation usually result in pests such as mealy bug, aphids, white fly or rust and powdery mildew. Consult the nearest garden centre to find out what the latest and best suited pesticides and fungicides are for the problems.
