Propagation Techniques
Seed Propagation
Though not too common, propagating through seeds is possible. Collect seeds in the fall and plant them in a seed starting mix, providing warmth and moisture for successful germination.
Cutting Propagation
A more popular method, stem cuttings can be taken from healthy plants. Use the following steps:
- Take 4 to 6-inch cuttings from the tips of healthy branches in spring or early summer.
- Remove the lower leaves and dip the cut end in rooting hormone.
- Plant the cutting in a well-draining potting mix and water lightly.
- Cover the pot with a plastic bag to maintain humidity until roots develop, typically around 4-6 weeks.
Division
Dividing established plants is another suitable method for propagation. During early spring, carefully uproot the plant and separate the root ball into smaller sections, each with its own set of stems.
