Propagation of Pelargonium peltatum (L.) L'Hér.

Pelargonium peltatum, commonly known as ivy leaf geranium or cascading geranium, is a popular flowering plant among gardeners due to its ease of cultivation and attractive foliage. The plant can be propagated via various methods:

1. Stem cuttings:

Stem cuttings are the most common and efficient method of propagating Pelargonium peltatum. Cuttings taken from actively growing plants are more likely to root successfully. The ideal time for taking cuttings is early spring when the new growth appears or in late summer when the plant has finished flowering. Cuttings should be around 7-10cm long and taken from the tip of the stem.

Dip the cuttings in a rooting hormone powder and plant them in a propagation mixture of peat moss and sand or perlite. Cover the container with a plastic sheet to create a humid environment and place it in a well-lit area, but away from direct sunlight. Keep the soil moist, and roots should develop within 4-6 weeks.

2. Division:

Pelargonium peltatum can also be propagated through division. The plant's root ball is gently lifted and separated into two or more sections. Each section should have its own root system and at least one vigorous shoot. Replant the divisions in a well-draining potting mix and water regularly.

3. Seeds:

Although uncommon due to its unpredictable and lengthy process, Pelargonium peltatum can also be propagated via seeds. Fresh seeds should be sown in a seed tray filled with a well-draining potting mix that is kept moist and placed in a warm, well-lit area. Germination can take up to several weeks, and seedlings should be transplanted into individual pots once they are large enough to handle.

Overall, Pelargonium peltatum is a plant that is easy to propagate using stem cuttings and division. Propagation via seeds can be time-consuming, and the results are often unpredictable. Choose the propagation method that suits your preferences and experience.

Introduction
