Propagation of Chassalia bonifacei Thulin & S.Manktelow
Chassalia bonifacei Thulin & S.Manktelow is a rare and endangered shrub species found in the forests and savannas of Madagascar. While it is possible to propagate the plant through seeds, it is a challenging process due to the plant's complex germination requirements. Therefore, vegetative propagation methods such as stem cuttings and layering are more commonly used.
Propagation by Stem Cuttings
The best time to take stem cuttings from Chassalia bonifacei is during the active growth period, which occurs in the spring and early summer months. Cuttings should be taken from healthy, disease-free plants with a diameter of at least 6mm and a length of 10-15cm. The cuttings should be taken from the current year's growth and be free of flowers and buds.
After taking the cuttings, remove the lower leaves and dip the cut ends into a rooting hormone before planting them in a well-draining, sterile potting medium. The cuttings can be planted in individual pots or in a communal container with spacing of 3-5cm between each cutting. Provide the plants with regular moisture and humidity until the roots have established, which can take 6-8 weeks.
Propagation by Layering
Layering is another method of vegetative propagation that is commonly used for Chassalia bonifacei. This method involves bending a lower branch of the plant and burying part of it in the soil, allowing it to form roots while still attached to the parent plant.
To propagate through layering, select a healthy, low-lying branch and wound it by making a small incision on the bark. Dust the wound with rooting hormone and gently bend the branch to the ground, keeping it in contact with the soil. Cover the wound and the buried section of the branch with soil and stake it in place if necessary. Water the plant frequently until the new roots have established, which can take several months. Once the new plant has rooted, it can be separated from the parent plant and transplanted into its own container or location.
