Cultivation
Bupleurum angolense C.Norman is a hardy perennial plant that thrives in full or partial sunlight. It is well-suited to grow in well-drained soils that are rich in organic matter. Seedlings are the easiest and most commonly used method to cultivate Bupleurum angolense C.Norman. It is recommended to sow the seeds in a seedbed in early spring. The plants can be transplanted into their final spot in the garden after they have reached a height of 10-15cm.
Watering Needs
Bupleurum angolense C.Norman requires moderate watering throughout the growing season. It is essential to avoid overwatering, which may lead to root rot, especially in poorly drained soil. One inch of water per week is sufficient for the plant, although the rainfall in the area can also supplement it. It is recommended to water the plant at the base as opposed to from overhead to prevent moisture from accumulating on the leaves.
Fertilization
Bupleurum angolense C.Norman is a moderately slow-growing plant that doesn't require much fertilizer. Applying organic compost or well-rotted manure will enhance the soil quality and improve the plant's growth. It is advisable to fertilize the plant in early spring as it begins active growth. In the blooming stage, using a low-nitrogen, high-phosphorus fertilizer can promote blooming and flowering.
Pruning
Bupleurum angolense C.Norman requires minimal pruning, although pruning can help to shape the plant and promote bushiness. It is recommended to prune the plant in early spring before it begins growing actively. Prune away any dead, diseased, or damaged foliage, preventing the likelihood of any potential pests or diseases, or aiding in the pest's removal. Cut back any leggy stems that lack leaves or flowers to promote a bushier plant.
Propagation of Bupleurum Angolense C.Norman
Bupleurum angolense C.Norman or commonly known as Angola hare's ear is a perennial plant that belongs to the Apiaceae family. Propagation of this plant can be done through different methods, including seeds and cuttings. Here are the propagation methods for Bupleurum angolense C.Norman:
Propagation through Seeds
Bupleurum angolense C.Norman can be propagated through seeds. It's best to plant the seeds in early spring, as this is the time when the soil is moist, and the temperature is mild. To start, prepare a well-draining soil mix and sprinkle the seeds on top of the soil. Cover the seeds lightly with soil and water gently. Keep the soil moist and ensure that the seeds are kept in a warm place where it can receive enough light.
After three weeks, the seeds will start to germinate. Be patient and wait until the seedlings are strong enough to handle. Once they've grown several leaves, you can transplant them into separate pots. When planting the seedlings, make sure to keep them at least 10-15cm apart from each other. Make sure to water them regularly, but do not let the soil become too wet.
Propagation through Cuttings
Bupleurum angolense C.Norman can also be propagated through cuttings. This method is suitable for those who aren't confident in growing plants from seeds. In this method, take cuttings from healthy plants. Make sure you choose a healthy branch that has no signs of disease or damage.
Cut off a 15-20cm stem, remove all the leaves from the bottom two-thirds of the stem, and dip the cut end in rooting hormone. After that, insert the stem into a soil mix that's half perlite and half peat moss. Water the cutting gently and keep it in a sunny, warm place. In a few weeks, the cutting should start to grow roots. Once the roots are about 2-3cm, you can transplant them to a separate pot.
Propagation of Bupleurum angolense C.Norman through seeds or cuttings is easy and straightforward. By following the steps in the propagation methods, you'll have more plants that you can nurture and grow.
