Propagation of Oxyanthus zanguebaricus
Oxyanthus zanguebaricus (Hiern) Bridson, commonly known as African star flower, is a small shrub that belongs to the Rubiaceae family. If you want to propagate this plant, you should know that there are several methods you can use.
Seed Propagation
The most common way of propagating Oxyanthus zanguebaricus is from seeds. To do this, you need to collect the seed pods when they turn brown and slightly dry. Remove the seeds from the pods and soak them in warm water for 24 hours to soften the seed coat.
After soaking, plant the seeds in a well-draining potting mix. Cover the seeds with a thin layer of soil and mist them with water. Place the pot in a warm and bright location, ideally with indirect sunlight. Keep the soil moist and within a few weeks, the seeds will germinate.
Cuttings Propagation
You can also propagate Oxyanthus zanguebaricus from cuttings. Take a 4-6 inches long cutting from the mother plant, making sure to cut below a node. Remove the lower leaves and dip the end of the cutting in rooting hormone.
Insert the cutting in a potting mix that is well-draining. Keep the soil moist and place the pot in a warm and bright location, preferably with indirect sunlight. In a few weeks, the cutting will develop roots and new growth will appear.
Division Propagation
Lastly, you can propagate Oxyanthus zanguebaricus through division. This means separating a clump of the mother plant into smaller sections. To do this, carefully dig out the plant and gently separate the roots into smaller sections. Each section should have at least one stem and some roots.
Plant each section in a pot that has well-draining soil and water it thoroughly. Keep the pot in a warm and bright location, preferably with indirect sunlight. In a few weeks, the plant will establish new roots and start to grow new shoots.
