Propagation of Pittosporum Viridiflorum Sims Subsp. Somalense Cufod.
Pittosporum viridiflorum Sims subsp. somalense Cufod. is commonly known as the Somali Pittosporum. It is a small tree that is native to East Africa and forms a dense evergreen canopy. The plant has a rounded to spreading shape, with a height of up to 10 meters. Propagation of the Somali Pittosporum can be done through several methods, including seeds, cuttings, and grafting.
Propagation by Seeds
Propagation by seed is one of the most straightforward methods for Pittosporum viridiflorum Sims subsp. somalense Cufod. It is essential to obtain fresh seed because it has a short viability period. The seed should be sown in a well-draining soil mixture and kept moist until germination. Germination can take up to three months, and once the seedlings reach a height of around 10cm, they can be transplanted.
Propagation by Cuttings
Cuttings can be taken from either woody or herbaceous material. Woody cuttings are best taken from mature stems, while herbaceous cuttings can be taken from softwood. The cutting should be around 10-15 cm in length, with several nodes. The lower leaves should be stripped, and the cutting should be dipped in rooting hormone before planting. The cutting should be placed in a well-draining soil mixture, kept moist, and placed in a warm and bright location. It can take up to six months for the cutting to root and establish itself.
Propagation by Grafting
Grafting is a preferred method for Pittosporum viridiflorum Sims subsp. somalense Cufod. because it ensures that the desirable traits of the parent plant are passed on to the offspring. Grafting is done by taking a scion from the parent plant and attaching it to a rootstock. The scion should be taken from a mature and disease-free tree. The rootstock should be of the same species and grown from either cuttings or seedlings. Once the graft has taken, the plant can be cared for as usual.
Disease and Pest Management for Pittosporum viridiflorum Sims subsp. somalense Cufod.
Pittosporum viridiflorum Sims subsp. somalense Cufod., also known as the Somali Pittosporum, is a small tree that is native to the Horn of Africa. Despite being a hardy plant, it is susceptible to various diseases and pests. Here are some common issues that might affect the plant and ways to manage them:
Diseases
Leaf Spot: This fungal disease shows up as brown or black spots on the leaves. It can be prevented by providing good drainage and avoid overhead watering. If the disease occurs, remove the infected leaves and apply a copper-based fungicide to the plant.
Root Rot: Over-watering and poor drainage can cause this disease. Symptoms include yellowing leaves and a rotten smell emanating from the roots. To manage this disease, ensure proper drainage, avoid over-watering and destroy infected plants to prevent the spread.
Dieback: This disease is caused by a fungus that attacks the branches, causing them to die. Prune off the infected branches and apply a fungicide spray. Ensure good sanitation practices and remove infected branches from the garden to avoid spreading.
Pests
Scale Insects: These pests suck sap from the plant, causing yellowing of leaves and defoliation. Use a systemic insecticide to manage the infestation.
Mealybugs: These small insects form colonies on the plant, causing stunted growth and yellowing of leaves. Spray the plant with insecticidal soap or neem oil to get rid of the infestation.
Aphids: These small insects suck sap from the leaves, and their waste products cause sooty mold to grow. Spray the plant with insecticidal soap to remove the infestation.
Overall, it is crucial to keep a keen eye on the plant's health and take proactive measures to protect it from diseases and pests. Maintaining good cultural practices such as proper drainage, adequate air circulation, regular pruning, and providing sufficient light and water can help keep the plant healthy.
