About soil condition, pittosporum shrub prefers well-drained soil, and it will also grow in sandy soil as long as it is well-drained. It is not particular about pH, and it will even do well in chalky soil. It is not very drought tolerant, so make sure to water it regularly, especially during hot, dry weather.
Just like other pittosporum shrubs, the sun light requirement for this shrub is 6 hours of sun exposure daily. The sun light requirement is very important for the growth and development of the pittosporum shrub. If the sun light requirement is not met, the shrub will not grow and develop properly.
The temperature condition that is most ideal for the Pittosporum shrub is one that is warm and humid. This type of climate is typically found in regions that are close to the equator, such as in tropical areas. The shrub requires a lot of moisture in order to thrive, so a warm and humid climate is essential for its growth. Additionally, the Pittosporum shrub is also able to tolerate a wide range of temperatures, from hot to cold. However, it should be noted that the shrub will not do well in climates that are too dry or too wet.
Ideal humidity condition for this plant is 50%. They are not too particular about humidity levels, however, so as long as the air is not too dry, they will be fine. They do best in bright, indirect light but can also tolerate some direct sun.
About fertilizer, this family of plant is not too demanding and does best with a general-purpose fertilizer applied in early spring and again in mid-summer. As for the root, it is best to plant pittosporum in soil that is acidic, organic and well-drained.
Pruning is an important aspect of pittosporum shrub care. Pruning helps to control the shape and size of the plant, as well as encourage new growth. When pruning, it is important to make clean, sharp cuts. This will help prevent the spread of disease and ensure that the plant heals properly.
Propagation is best done by taking stem cuttings in late spring or early summer, when the weather is warm and the plant is actively growing. Cuttings should be taken from young, healthy stems that are about 6 inches long. Make sure to take cuttings from the current year's growth, as older stems will be more difficult to root. To take a cutting, use a sharp knife to make a clean cut just below a leaf node (where the leaves join the stem).Remove the lower leaves from the cutting, leaving 2-3 leaves at the top. Dip the cut end of the stem in rooting hormone, then plant the cutting in a pot filled with moistened perlite or sand. Cover the pot with a plastic bag to create a humid environment, and place it in a warm spot out of direct sunlight. Water the cutting regularly to keep the perlite or sand moist, but not soggy. After 4-6 weeks, you should see new growth appearing on the cutting. At this point, you can remove the plastic bag and begin watering the cutting as you would a normal pittosporum plant.
Usually, the plant growth rate is fast, meaning the plant will grow relatively quickly compared to other plants. There are some cultivars, however, that have a slow growth rate. When choosing a pittosporum shrub for your landscape, be sure to check the growth rate to ensure it will fit in with your desired look.
Common problems for this kind of plant are dull leaves, compact growth, and black sooty mold. Treating with horticultural oil or neem oil usually takes care of the mold problem. Black sooty mold is a common fungal disease that affects many types of plants, including pittosporum. The fungus grows on the honeydew secreted by aphids and other sucking insects. While the fungus itself does not harm the plant, it can cause the leaves to become dull and discolored. To control black sooty mold, it is important to first control the insect pests that are producing the honeydew.
