You can create more plants by propagating the ones you have with two different techniques: root cutting and air layering.
The air-layering technique is great for indoor plants.
Air Layering How-To
- Remove all leaves along the stem of your house plant, tree, or shrub; use a one- or two-year-old growth.
- Remove a V-shaped segment of stem to about the middle of the stem (not too far or the stem will break).
- Brush the cut surface with rooting hormone.
- Wrap the entire stem in moist sphagnum moss.
- Surround and seal the moss with plastic wrap.
- Surround plastic wrap with tin foil.
- In 2 to 3 months, the stem will be rooted and the plant can be removed and potted.
The root-cutting technique can be used with a number of outdoor plants, such as oriental poppies, Crambe maritime and Crambe orientalis, Verbascum, Eryngium or sea hollies, Acanthus mollis or bear’s breeches, and horseradish root.
Root Cutting How-To
- Remove plant from pot and shake off excess dirt.
- Remove the largest of the roots, generally the size of your little finger or smaller for most plants.
- Cut these into 2-to-3-inch lengths, making sure that you keep the top end correctly identified.
- Push each segment into a pot of potting soil so the tops are level with the soil.
- Top off the pot with chicken grit or pea gravel.
- Water and place in a cool area protected from extreme temperatures.
- Each root will develop into an individual plant and can be transplanted into the garden the following autumn.
