Propagation of Pittosporum lanatum Hutch. & E.A.Bruce
Pittosporum lanatum Hutch. & E.A.Bruce, commonly known as the woolly pittosporum, is an evergreen shrub or small tree native to New Zealand. It is commonly propagated by cuttings and seeds.
Propagation by cuttings
The woolly pittosporum can be propagated by stem cuttings taken in summer or early autumn. The cuttings should be about 10cm long and taken from semi-hardwood. The leaves should be removed from the bottom half of the cutting, and the stem should be dipped in rooting hormone before being planted in an appropriate potting mix. The cuttings should be kept moist and in a warm, shaded area until roots have formed.
Propagation by seeds
The woolly pittosporum can also be propagated by seeds. The seeds should be collected in autumn when the pods have split open. They should be soaked in water for a day before being sown in a well-draining potting mix. The pots should be kept moist and in a warm, shaded area until the seeds have germinated.
It should be noted that the woolly pittosporum is slow growing, and it may take up to 2 years for the plant to reach a size suitable for transplanting.
Disease and Pest Management for Pittosporum lanatum Hutch. & E.A.Bruce
Pittosporum lanatum Hutch. & E.A.Bruce, commonly known as woolly pittosporum, is a species of flowering plant native to China. As with any plant, woolly pittosporum is susceptible to diseases and pests that can damage or destroy it if not managed properly. Here are some common diseases and pests that might affect the plant and ways to manage them:
Diseases
Leaf spot disease: Leaf spot is a fungal disease that causes brown or black spots on the leaves. To manage this disease, remove any infected leaves and debris from the ground. Apply a fungicide to protect the remaining foliage.
Root rot: Root rot is a fungal disease that attacks the roots, causing them to become black and mushy. This disease is difficult to manage once it has set in, so prevention is key. Make sure the plant is in well-draining soil and avoid overwatering.
Bacterial canker: Bacterial canker is a disease that causes the stems to turn black and ooze a yellowish liquid. To manage this disease, prune the affected branches and destroy them. Apply a copper-based fungicide to the remaining plant.
Pests
Mites: Spider mites are a common pest that can cause damage to the foliage of woolly pittosporum. To manage mites, spray the plants with a strong stream of water to dislodge them from the leaves. Apply insecticidal soap or neem oil to kill any remaining mites.
Scale insects: Scale insects are small, brown or grey insects that attach themselves to the stems and leaves of the plant. To manage scale, prune the affected branches and destroy them. Apply neem oil or a horticultural oil to the remaining plant.
Aphids: Aphids are small, green insects that can suck the sap out of the plant, causing it to wilt and deform. To manage aphids, spray the plants with water to dislodge them from the leaves. Apply insecticidal soap or neem oil to kill any remaining aphids.
Implementing a regular monitoring and maintenance program can be a successful approach to avoid serious infestation by pests and diseases. By recognizing the early symptoms of infestation and infection, the plant can be directly treated. By providing proper and favorable growing conditions with a balanced watering schedule, feeding the plant with a special fertilizer, and pruning affected parts, the survival of the plant will increase.
