Geraniums, a perennial known for profuse clustered blooms and hardy foliage, originated in South Africa. These versatile plants do well in flowerbeds, boxes, pots, hanging pots, container gardens and even as a ground cover on hillsides. Geraniums, scientifically known as Pelargonium hortorum, root from cuttings. This method, referred to as asexual propagation because it allows the development of a new plant without fertilisation, requires only growing material and a container for the successful creation of new geranium plants.

Things you need
- Garden clippers or sharp knife
- Rooting hormone (optional)
- 4-inch-deep containers with drainage holes
- Clean gravel or small rocks
- Coarse sand
- Watering can or hose with misting attachment
Fill 4-inch-deep containers to within 1 inch of the top with moist sand. Water so it is damp but not saturated.
Cut sections of geranium stems 4 to 5 inches long at a 45-degree angle. Clip off the leaves on the bottom half of the stem.
Shake some rooting hormone into a saucer and roll 1/2 inch of the angled end of the geranium cuttings in the powder.
Stick 1 1/2 inch of the cutting into the sand. Press the sand around the cutting.
Add more cuttings, leaving at least 3 inches between cuttings.
Arrange a plastic bag loosely over the container to retain the dampness in the sand.
Move the container of cuttings to a warm location with bright, indirect sun.
Remove the plastic and check the sand once a week. The original moisture will usually last at least a month before the sand requires more water.
Pull on the stems carefully after three to four weeks. When the stems resist pulling, pot them individually in potting soil.
Tips and warnings
- Take cuttings from healthy, well-established geranium plants.
- Open the plastic for a few minutes on hot days to avoid overheating the cuttings.
- Water in the evenings or early morning during hot weather.
- Avoid over-watering to prevent rotting the roots.
