Pittosporum terminalioides Planch. ex Gray var. macrocarpum Sherff requires moderate fertilization to maintain optimal growth and health. The plant can be fertilized with a slow-release granular fertilizer in early spring or late winter. It is recommended to avoid high nitrogen fertilizers that can cause excessive vegetative growth. Instead, use balanced fertilizers such as 10-10-10 or 16-16-16, depending on the soil nutrient content and the plant's growth stage.
Pruning of Pittosporum Terminalioides Planch. ex Gray var. Macrocarpum Sherff
Pittosporum terminalioides Planch. ex Gray var. macrocarpum Sherff requires occasional pruning to remove dead or damaged branches and to maintain its shape and size. Pruning can be done in early spring or late winter before the new growth phase. It is recommended to use sharp and clean pruning tools to avoid damaging the plant and to make clean cuts. The plant can be pruned to maintain a desired height and shape, but avoid over-pruning that can stress the plant and affect its growth and health.
Propagation of Pittosporum Terminalioides Planch. ex Gray var. Macrocarpum Sherff
Pittosporum terminalioides Planch. ex Gray var. macrocarpum Sherff, commonly known as the giant pittosporum, is a species of plant found in the Philippines. It is an evergreen tree or shrub that produces large, fragrant flowers. The plant can be propagated through different methods, as follows:
Seed Propagation
Propagation by seed is one of the most common methods. To propagate the plant by seed, collect the ripe fruit from the plant and remove the seeds. Clean the seeds with water to remove any remaining flesh and dry them. Sow the seeds in a well-draining mix and keep them moist. Germination can take from 1 to 3 months. Once the seedlings have developed, transfer them to individual pots or to the field.
Cuttings
The pittosporum can also be propagated through cuttings. Take semi-hardwood cuttings measuring 6 to 8 inches from healthy plants. Dip the cuttings in rooting hormone and insert them into a well-draining medium. Keep the soil moist but not waterlogged, and provide partial shade. When roots have developed and new growth appears, transfer the plants to their permanent location.
Air Layering
Air layering is a method of propagation for the plant. Choose a healthy stem and make a cut about 1/3 of the way through the stem. Apply rooting hormone to the area and wrap the stem with moist sphagnum moss or another suitable material. Cover the moss with plastic wrap and secure with tape or a rubber band. Keep the moss moist and wait for roots to develop. Once the roots have developed, cut the stem below the roots and plant the new plant in a suitable pot or location in the ground.
Propagation of Pittosporum Terminalioides Planch. ex Gray var. Macrocarpum Sherff is a relatively straightforward process. By following any of the above methods, growers can quickly produce new plants of this valuable species.
Disease and Pest Management for Pittosporum Terminalioides Planch. ex Gray var. Macrocarpum Sherff

Like all plants, it is susceptible to a range of diseases and pests that can negatively impact its growth and appearance. In this article, we will explore the common diseases and pests that affect this plant and suggest ways to manage them.
Common Diseases
The Large-Fruited Pittosporum is susceptible to a range of fungal diseases that can cause leaf spots, blights, and cankers. These diseases are often caused by infestations of pathogens that thrive in moist and humid conditions. The following are the most common diseases that affect this plant:
- Anthracnose - This fungal disease causes brown spots on the leaves that can eventually lead to defoliation. It can be managed by removing infected leaves and branches and applying a fungicide.
- Leaf spot - This fungal disease causes circular spots on the leaves that can be dark brown or black. It can be managed by removing infected leaves and branches and improving air circulation and drainage.
- Canker - This fungal disease causes sunken lesions on the branches that can lead to dieback. It can be managed by removing infected branches and applying a fungicide.
Common Pests
The Large-Fruited Pittosporum is also susceptible to a range of pests that can feed on its foliage and suck sap from its shoots and stems. The following are the most common pests that affect this plant:
- Aphids - These small insects can feed on the sap of the leaves and cause them to curl and distort. They can be managed by spraying the plant with a strong jet of water to dislodge them or by applying an insecticidal soap.
- Scale insects - These small insects form hard, waxy shells on the leaves and stems and can suck sap from the plant. They can be managed by removing infected leaves and branches and applying a horticultural oil or insecticidal soap.
- Spider mites - These tiny arachnids can feed on the undersides of the leaves and cause them to turn yellow and brown. They can be managed by improving air circulation and humidity levels, or by applying an insecticidal soap.
In conclusion, the Large-Fruited Pittosporum is a beautiful and valuable plant that requires proper care and attention to stay healthy and pest-free.
