Galium bussei K.Schum. & K.Krause var. glabrostrictius Brenan, also known as Busse's bedstraw, is a sprawling perennial plant native to Africa. It grows best in full sun to partial shade and well-draining soils. Propagation of this plant can be achieved through various methods.
Seed Propagation
Propagation of Busse's bedstraw by seed is quite easy. Collect the matured seeds and sow them during the spring or fall seasons. The seeds must be planted in pots or trays filled with a well-draining potting mix. The seeds require light to germinate, so they should not be buried deep. Water the pots thoroughly, and place them in a warm and bright area.
Cuttings Propagation
Busse's bedstraw can also be propagated through cuttings. Cut a healthy stem of the plant, about 6 inches long, just below a leaf node. Remove the lower leaves, and dip the cut end into rooting hormone. Gently plant the cutting into a pot of well-draining potting mix. Place the pot in a warm and bright area, and water regularly. The cutting will start to form roots in about four to six weeks.
Division Propagation
Division is the most preferred method for propagating Busse's bedstraw. This method can be done during the growing season. Dig up the plant gently and divide it into several equal sections using a sharp knife. Each section must have roots, stems, and leaves. Plant each section in a pot or directly in the ground. Water thoroughly, and place in a bright area. The divided plants will start to grow within a few weeks.
Disease Management
Galium bussei K.Schum. & K.Krause var. glabrostrictius Brenan is generally susceptible to foliar and stem diseases. Here are some common diseases that might affect the plant and ways to manage them:
- Leaf spot: This disease generally causes small, circular spots on leaves that eventually merge into larger patches. It is caused by fungi and can be managed by removing infected plant parts, avoiding overhead irrigation, and applying fungicides.
- Powdery mildew: This fungal disease appears as a powdery white coating on the leaves, stems, and flowers. It can be prevented by keeping humidity low and avoiding overcrowding of plants. Fungicides can also help control powdery mildew.
- Root rot: This disease is caused by fungi that thrive in wet soil. It causes the plant to wilt and die. Overwatering can exacerbate root rot. To manage this disease, avoid overwatering, improve soil drainage, and apply fungicides.
Pest Management
Galium bussei K.Schum. & K.Krause var. glabrostrictius Brenan is generally resistant to pests, but here are some that might affect the plant and ways to manage them:
- Aphids: These pests suck sap from the plant and excrete a sticky substance that attracts ants. They can be managed by washing them off with a strong stream of water or by applying insecticidal soap.
- Spider mites: These pests are tiny and can be difficult to spot. They cause yellowing and stippling of the leaves. They can be managed by applying insecticidal soap or horticultural oil.
- Whiteflies: These pests are small and fly around when the plant is disturbed. They excrete a sticky honeydew that can attract other pests like ants and sooty mold fungus. They can be managed by applying insecticidal soap or horticultural oil.
