To propagate a Kwanzan cherry tree, you can take a cutting from a healthy branch and place it in a moist medium. The best time to do this is in late spring to early summer.
Steps
- Select a branch with 2–4 leaf nodes
- Cut a 4–8 inch section of the branch at a horizontal angle
- Remove the leaves from the bottom 2/3 of the cutting
- Dip the cut end of the cutting in rooting hormone
- Place the cutting in a container with a mixture of perlite and peat moss
- Water the cutting and cover it with a plastic bag
- Place the container in a sunny location
- Mist the cutting twice a day to keep the soil moist
- After a few months, check if the cutting has rooted by gently tugging on it
- If the cutting is rooted, transfer it to a larger container with potting soil
