However, avoid over-fertilization as it can lead to excessive vegetative growth and reduce flowering.
Water Requirements: Pittosporum viridiflorum Sims var. afrorientale (Cufod.) Cufod. prefers moderate watering and does not tolerate drought or waterlogging. Keep the soil moist but not wet during the growing season and reduce water during the dormant phase.
Pruning Requirements: Prune the plant regularly to maintain its shape and size. It is best to prune in late winter or early spring before new growth appears. Remove dead, diseased, or damaged branches and thin out crowded growth to improve air circulation and sunlight penetration.
Cultivation
Pittosporum viridiflorum Sims var. afrorientale (Cufod.) Cufod. prefers well-drained soils with plenty of organic matter and a pH range of 6.0 to 7.0. It can grow in full sun or partial shade, but will require more watering if grown in full sun.
Watering Needs
This plant should be watered deeply once a week to maintain adequate soil moisture. However, it is essential to be careful not to overwater, as this can cause root rot. As with most plants, it is best to water in the early morning or late afternoon to avoid evaporation.
Fertilization
Pittosporum viridiflorum Sims var. afrorientale (Cufod.) Cufod. can benefit from regular fertilization during the growing season. Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK). Apply the fertilizer according to the instructions on the package.
Pruning
Pruning is necessary to maintain the shape and size of the Pittosporum viridiflorum Sims var. afrorientale (Cufod.) Cufod. plant. Pruning should occur during the dormant season (winter) to avoid damaging new growth. Trim off any dead or damaged branches using clean, sharp pruning shears, making a clean cut just above a bud or lateral branch. To encourage bushier growth, pinch out the tips of the new growth in early spring.
Propagation of Pittosporum viridiflorum Sims var. afrorientale
Pittosporum viridiflorum Sims var. afrorientale, also known as the Eastern Cape cheesewood, is a slow-growing, evergreen shrub or small tree native to South Africa.
Seed Propagation
Propagation of Pittosporum viridiflorum Sims var. afrorientale is primarily done from seeds. It is best to collect seeds from the tree during autumn and sow them immediately.
The seeds should be sown in a well-draining potting medium and covered lightly with soil. Water the seeds and place the pot in a warm location, out of direct sunlight. Germination should occur within 3-6 weeks.
Transplant the seedlings to individual pots once they are large enough to handle. Allow them to grow for one or two years before transplanting them into the ground.
Cuttings Propagation
Propagation of Pittosporum viridiflorum Sims var. afrorientale can also be done from semi-hardwood cuttings taken from the plant during summer. Cuttings should be 6-10 cm in length and should be taken from the tips of healthy branches.
Dip the lower cut end of the cutting in rooting hormone and plant it in a well-draining potting medium. Water the cutting and cover it with a plastic bag to retain moisture. Place the pot in a warm, shaded location and keep the soil moist until the cutting roots, which should take about 6-8 weeks.
Transplant the rooted cutting into a larger pot and allow it to grow for one or two years before transplanting it into the ground.
Disease Management
Pittosporum viridiflorum Sims var. afrorientale is susceptible to various fungal infections such as leaf spot, powdery mildew, and root rot. To manage these diseases, it is essential to ensure good plant hygiene by removing and destroying the infected plant parts.
Applying fungicides can also help manage fungal diseases. Using fungicides preventively according to the manufacturer's instructions can protect the plant from infections. Chemical treatments should only be used as a last resort.
Overwatering and poor drainage can contribute to root rot. Ensuring well-draining soil and watering plants at appropriate intervals can help manage root rot.
Pest Management
Common pests that may affect Pittosporum viridiflorum Sims var. afrorientale include the Pittosporum psyllid, spider mites, and scale insects.
To manage pests, it is essential to monitor the plant regularly for signs of infestation, such as stunted growth, yellowing leaves, or distorted leaves.
Introducing natural predators of pests, such as ladybugs or lacewings, can help control pest populations. Removing infected plant parts and using insecticidal soap can also help manage pests. Neem oil, a natural insecticide, may also be effective against some pests.
Chemical pesticides should only be used as a last resort and in accordance with label instructions, as they can harm beneficial insects and pollinators and are harmful to the environment.
