Pelargonium glutinosum can easily be grown from seeds and cuttings. Cuttings can be grown at any time of the year. Take semi-mature stem cuttings of 150 mm long and apply a rooting hormone to stimulate the rooting process. Insert them into prepared holes made by a wooden dibber or a nail to avoid damaging the ends. The cuttings are then placed in a coldframe to root. Rooting of this species 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.

Pelargoniums can also be grown from seed in late summer and early autumn. Sow the seeds in a light, well-drained potting soil. 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 4 weeks. Pelargoniums grown from seed are generally more vigorous than those made from cuttings. They do tend to take longer to produce flowers. Remember that plants grown from seed will show some degree of variation and if a particular form or variant is required it must be propagated vegetatively, by cuttings. The plant can grow easily in a garden where the soils are fairly damp and moist. It is relatively fast-growing, showy and long-flowering.
