Lachnostylis bilocularis R.A.Dyer, commonly known as the African evergreen, is a beautiful and resilient plant that can add value to any garden. It is relatively easy to cultivate and can thrive in various conditions. The plant can germinate from both seeds and cuttings, but it is easier to grow it from cuttings.
The best time to take cuttings is in spring when the plant is actively growing. Use a sterile blade to take a cutting from a healthy stem with leaves. Remove the bottom leaves and dip the end in rooting hormone before planting it in a well-draining soil mix. The cutting should root in a few weeks.
Watering needs for Lachnostylis bilocularis R.A.Dyer
Lachnostylis bilocularis R.A.Dyer is drought tolerant, but like any plant, it needs water to survive. Watering the plant once a month or when the soil is dry is enough. Ensure the soil is well-draining to avoid root rot.
Overwatering can cause the plant to wilt, and the leaves will turn yellow. If this happens, reduce watering and ensure the soil is dry before watering again.
Fertilization for Lachnostylis bilocularis R.A.Dyer
Fertilizer is not necessary for Lachnostylis bilocularis R.A.Dyer, but adding compost to the soil can improve its growth. Adding a thin layer of compost to the soil during the growing season can provide the necessary nutrients for the plant.
Avoid using fertilizer with high nitrogen content. High nitrogen levels can cause the plant to grow too quickly, and it can damage the roots and stems.
Pruning Lachnostylis bilocularis R.A.Dyer
Pruning Lachnostylis bilocularis R.A.Dyer is not necessary, but a gentle prune can help shape the plant and remove dead or diseased branches. Prune the plant after the blooming season to ensure it has time to recover before the next flowering season.
When pruning, use sharp and clean pruning shears to avoid damaging the plant. Prune the stem about 1/4 inch above a healthy leaf to promote healthy growth.
Propagation of Lachnostylis bilocularis R.A.Dyer
Lachnostylis bilocularis R.A.Dyer, commonly known as the African honey bell, is a small shrub native to South Africa. It is a member of the family Asteraceae and produces attractive pink to mauve flowers. Propagation of this plant can be achieved through different methods, which include:
Seed propagation
Seeds of L. bilocularis can be collected once they have developed a grayish color and have started to fall off the plant. These seeds can then be sown directly into seed trays filled with a mix of sand and compost, which should be kept moist. Germination should be expected within 2 to 3 weeks.
The seedlings should be kept in a well-lit area and be protected from direct sunlight. Once they are large enough, they can be transplanted into individual pots with a suitable potting mix, containing coarse river sand, peat and loam.
Cuttings propagation
L. bilocularis can also be propagated through cuttings, which should be taken from the current season's growth. Cuttings should be taken after the plant has finished flowering.
The cuttings should be about 8-10 cm in length and should have at least two nodes. The bottom pair of leaves should be removed, and the base should be dipped into rooting hormone before being planted into a propagation mix containing coarse river sand, perlite, and peat. The cuttings should be kept in a warm, humid environment and regularly watered until they develop roots, usually within 4-6 weeks.
Division propagation
L. bilocularis can also be propagated through division but the process can be a bit challenging. The parent plant must be carefully removed from the soil, and its roots separated while minimizing root damage. The separated plantlets should then be replanted into individual pots filled with potting mix.
In conclusion, L. bilocularis can be propagated through seed, cuttings, and division. However, seed propagation is the most straightforward and is recommended for amateur gardeners.
