How to Grow Pukatea

Cultivating Laurelia novae-zelandiae ( Laurelia novae-zelandiae ) is a rewarding endeavor for any gardener interested in New Zealand's unique flora. This species can be propagated through several methods, each requiring specific conditions to ensure healthy growth and establishment. Successful propagation depends on mimicking the plant's natural environment and providing consistent care during the early stages of development.

From Seed

Propagation from seed is often the most effective way to produce a large number of Laurelia Novae Zelandiae plants. Seeds should be collected when they are fully mature. Freshly collected seeds generally have higher germination rates than those that have been stored for long periods.

Sow fresh seeds in a seed-raising mix.

  1. Collect seeds
  2. Sow in trays

Keep moist until germination.

From Cuttings

For those wishing to replicate specific characteristics of a parent plant, vegetative propagation via cuttings is the preferred method. This technique ensures that the new plants are genetically identical to the source. Semi-hardwood cuttings taken during the appropriate season usually yield the best results for this species.

Take semi-hardwood cuttings in late summer.

  1. Take cuttings
  2. Use rooting hormone

Additional Methods

Depending on the growth habit of Laurelia novae zelandiae , other methods such as division or layering might also be viable options. Division is particularly suitable for plants that form dense clumps or have spreading root systems, while layering can be used for species with trailing or flexible stems.

Division can be done in early spring.

  1. Divide clumps
  2. Replant immediately

Pests & Diseases

Generally resistant to major pests.

While generally resilient, maintaining optimal growing conditions is the best defense against pests and diseases. Regular monitoring allows for early detection of any issues, which can often be managed through cultural practices or organic interventions. Ensuring good air circulation and appropriate watering will significantly reduce the plant's susceptibility to common environmental stresses and pathogens.

Cultural Significance

Laurelia novae-zelandiae , commonly known as pukatea, holds significant cultural importance, particularly within Māori traditions in New Zealand.The tree's bark was extensively used in traditional Māori medicine (rongoā) for its analgesic properties. It contains an alkaloid called pukateine, which has properties similar to morphine and was first isolated in 1910.Māori used the bark to alleviate toothaches by holding pulped inner bark in the mouth.A decoction made from the bark was used to treat ulcers, general skin complaints, and sexually transmitted diseases (STDs).It was also used to create tonics for digestive disorders, including gastric ulcers and stomach pains. Research suggests pukateine may even have a role in treating Parkinson's disease.Pukatea timber was valued for various uses. Māori crafted bowls, clubs, and paddles from its wood. It was also used to create figureheads for canoes.While the wood can become waterlogged, making it less ideal for large waka (canoes) where tōtara was preferred, its lightness made it suitable for river canoes.Early European settlers also utilized pukatea for boat building, weatherboards, and motor body construction. The wood is noted for being light, strong, difficult to split, and tending to dent rather than break upon impact.Pukatea also features in Māori proverbs and spiritual beliefs. An old Māori proverb uses the different properties of pukatea and tōtara wood as an analogy for youth and old age, with the waterlogged pukatea representing the elderly.The hollows that form in the centre of older pukatea trunks were sometimes used to conceal the bodies of deceased relatives to protect them from enemy raids.Furthermore, some individual pukatea trees were believed to possess the power to aid women in conception, with young women visiting these trees with a Tohunga (expert practitioner) to perform incantations.

Bonus Tip

Excellent for low-maintenance gardens.

For an extra boost, consider applying a thin layer of high-quality organic mulch around the base of the plant. This helps retain soil moisture, suppresses weeds, and gradually improves soil structure as it breaks down. This simple step can make a significant difference in the plant's overall vigor and resilience, especially during periods of extreme weather.
