Pelargonium abrotanifolium is easy to grow from cuttings, which can be taken at any time of the year. Soft, herbaceous stem cuttings should be taken and a rooting hormone for semi-hardwood applied, to stimulate the rooting process. The cuttings should be rooted in a cold frame, in a well-drained medium such as coarse river sand. Rooting will take place within three weeks. Once rooted, the cuttings are potted into a well-drained potting soil. The soil medium is made up of equal parts compost, coarse river sand and loam. Young plants can be fed on a monthly basis with an organic-based liquid or granular fertilizer.

Sow the seeds in a well-drained potting soil at the end of summer. Broadcast the seeds evenly in the seed tray, covering them with a layer of clean, white sand or fine milled pine bark. The depth of sowing is usually one-and-a-half times the size of the seed. Water thoroughly but gently and provide light shade. Germination usually takes place within three weeks. Pelargoniums grown from seed are generally more vigorous than those grown from cuttings. Young seedlings take longer to flower. Once the plant is established in your garden, it requires little maintenance and is fairly waterwise.
