Pruning:
Pruning Bertiera subsessilis Hiern var. subsessilis is not necessary unless you want to shape or control the size of the plant. If you want to prune, do it during late winter or early spring before new growth starts to emerge. Cut back any dead or diseased branches, and trim back the tips of the rest of the branches to encourage bushier growth. Avoid cutting out any branches that are more than half the diameter of the main stem as this can harm the plant.
Propagation of Bertiera subsessilis Hiern var. subsessilis
Bertiera subsessilis Hiern var. subsessilis can be propagated through a variety of methods including seed propagation, division, and stem cuttings.
Seed Propagation
Seeds of Bertiera subsessilis Hiern var. subsessilis can be harvested from ripe fruit and sown in a well-draining potting mix. They should be planted at a depth of approximately 1 cm and kept in a warm area with consistent moisture. Germination usually occurs within 2-4 weeks and the seedlings should be kept in a warm, bright area until they develop their second set of leaves. They can then be transplanted into individual pots and grown until they are large enough to be planted outdoors.
Division
Mature Bertiera subsessilis Hiern var. subsessilis plants can be divided to create new plants. This is typically done in the spring or fall by digging up the plant and separating it into several smaller sections. Each section should have a portion of the root system and a few stems. The divided plants can then be replanted in a new location or potted up and kept indoors until they have recovered and are ready to be planted outdoors.
Stem Cuttings
Stem cuttings of Bertiera subsessilis Hiern var. subsessilis can be taken in the spring or summer months. Cuttings should be taken from healthy, vigorous stems and should be approximately 10-15 cm in length. Remove the leaves from the lower third of the cutting and dip the cut end in rooting hormone. Insert the cutting into a well-draining potting mix and water well. Place the pot in a warm, bright area and keep the soil consistently moist. After a few weeks, roots should begin to form and the cutting can then be transplanted into individual pots or planted outdoors.
