Geraniums can be propagated in several ways: 1. Cuttings: Take a stem cutting from a healthy geranium plant and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a pot filled with a well-draining potting mix. Keep the soil moist and place the pot in a warm, bright area. 2. Division: Once a geranium has grown large enough, it can be divided into smaller plants. Gently lift the plant out of its pot and separate the rootball into smaller sections, making sure each section has several healthy stems and roots. Replant the sections in their own pots. 3. Seeds: Collect seeds from a geranium plant and plant them in a pot filled with a well-draining potting mix. Keep the soil moist and place the pot in a warm, bright area. Once the seedlings have grown large enough, transplant them into their own pots.
