How to Grow Pigeonwood
Pigeonwood, also known as Porokaiwhiri, is a graceful native New Zealand tree celebrated for its attractive, glossy green leaves, fragrant flowers, and clusters of bright orange-red berries. This medium-sized tree is a valuable addition to native plant gardens, providing year-round interest and attracting native birds. While it is a resilient and aesthetically pleasing tree, successful cultivation requires attention to its specific needs, particularly regarding moist, well-drained soil, and protection from harsh frosts when young. Understanding its propagation methods is key to successfully growing this delightful species.
From Seed
Propagating Pigeonwood from fresh seed is a viable method, though germination can be slow and may require stratification. Collect ripe berries in late autumn or early winter. Clean the seeds thoroughly to remove any fleshy pulp. Sow the seeds in a tray filled with a well-draining seed-raising mix, lightly covering them. The seeds typically require a period of cold stratification (e.g., refrigerate for 2-3 months) to break dormancy. Maintain consistent moisture in the seed tray and keep it in a warm, sheltered location. Germination can take several weeks to months after stratification. Once seedlings have developed a few true leaves, they can be potted into individual containers and grown in a sheltered environment before planting out.
From Cuttings
Semi-hardwood cuttings are a reliable method for propagating Pigeonwood, ensuring that new plants retain the exact characteristics of the parent. Take 10-15 cm cuttings from healthy, semi-hardwood stems in late summer or early autumn. Remove the lower leaves and dip the cut end in a rooting hormone. Insert the cuttings into a well-draining propagation mix (e.g., sand and perlite). Keep the cuttings in a warm, humid environment, out of direct sunlight, perhaps under a plastic dome or in a propagator. Rooting typically occurs within 8-12 weeks. Once rooted, the new plants can be potted on and grown in a sheltered environment until they are ready for planting.
Pests and Diseases
Pigeonwood is generally a robust tree, but it can be susceptible to certain pests and diseases, especially if not grown in optimal conditions.
Common Pests
- Aphids: Can infest new growth. Treat with insecticidal soap or remove manually.
- Scale Insects: May be present on stems and leaves. Treat with horticultural oil or appropriate insecticides.
Common Diseases
- Sooty Mould: Often associated with scale insect infestations, it can cover leaves and reduce photosynthesis. Address the underlying pest issue.
- Root Rot: Caused by overwatering or poor drainage. Ensure well-drained soil.
Good garden hygiene, proper watering, and adequate air circulation are key to preventing most pest and disease issues. Regular inspection will help catch problems early.
Cultural Significance
Hedycarya arborea, commonly known as pigeonwood or by its Māori name porokaiwhiri, holds significant cultural importance, particularly for Māori. The name "porokaiwhiri" itself reflects this, with "poro" meaning ball, "kai" meaning food, and "whiri" referring to a flock of birds, indicating that its fruit is a food source for birds.
Traditional Use of Hedycarya Arborea Wood for Musical Instruments:
- Pahū (drums or gongs): The wood was fashioned into these instruments.
- Pūrerehua (bull-roarer): This instrument was also made from porokaiwhiri.
- Pākuru: A percussion instrument consisting of two porokaiwhiri rods, where a longer rod was held in the mouth and a shorter one tapped a rhythm on it.
- Titi: Batons used in the stick-game called tititorea were made from pigeonwood.
- Rehu (flutes): Some flutes were also made from pigeonwood.
- Mouthpieces for shell trumpets: The wood was used for this purpose due to its sonorous nature.
Beyond musical instruments, Hedycarya arborea also played a role in sacred rituals. A fire-stick made from porokaiwhiri was sometimes chosen to light a sacred fire. This fire was used to burn the first hair cut from a child's head, a practice intended to destroy the hair and prevent its use for evil purposes (mākutu), as the head was considered sacred.
Bonus Tip
A Pigeon's Delight?
The common name 'Pigeonwood' comes from the fact that the native New Zealand pigeon, the kererā, is fond of its berries. However, it is now thought that the berries are not a preferred food source, but rather a 'famine food' that the birds will turn to when other, more desirable, foods are scarce. Interestingly, after gorging on the fruits, the birds can become drowsy!
