Propagation is the process of creating new plants from existing ones. Hydrangeas can be propagated from cuttings, divisions, or layering. Cuttings are the most common method of propagation and produce the most plants. To take a cutting, use a sharp knife or shears to cut a 6-8 inch (15-20 cm) stem from the mother plant. Make sure the cutting has at least 2-3 sets of leaves. Remove the bottom leaves and dip the cutting in rooting hormone. Plant the cutting in a pot filled with moistened potting mix and keep the soil moist. The cutting should root in 4-6 weeks. Once the cutting has rooted, it can be transplanted into the garden.
Usually, the plant growth rate is between 12 and 24 inches per season. However, new shoots can grow as much as 36 inches in a single season. The plant's size and growth rate depend on several factors, including the type of soil, the amount of sunlight, and the amount of water the plant receives.
