Cultural Significance Around the World

Manuka has long been an important plant in New Zealand and Australia, where it is also known as “Manuka.” In New Zealand, the blooming of Manuka flowers attracts bees, leading to the production of Manuka honey, which is highly valued for its distinct flavor and properties.

In Australia, Manuka is commonly used for landscaping in gardens and parks due to its resilience against dry conditions and strong winds. Its long-lasting flowers make it a popular ornamental plant.

In Japan, Manuka was introduced during the Meiji era as an ornamental shrub. It thrives in warm climates and is often cultivated in pots. Its elegant shape and delicate blossoms make it well-suited for bonsai, blending with traditional Japanese aesthetics.

Historical Background

Manuka has been used by indigenous peoples of New Zealand and Australia for centuries. The Māori people of New Zealand regard it as a “sacred tree” and have long incorporated it into daily life.

In the 18th century, British explorer James Cook observed that the local people brewed tea from Manuka leaves. He encouraged his crew to drink it, leading to the name “Tea Tree.”

By the 19th century, Manuka had gained recognition for its ornamental value and was introduced to Europe and America. Its popularity as a garden shrub grew, and new cultivars were developed. Today, Manuka is widely planted in gardens and parks around the world for both its aesthetic appeal and functional benefits.

Gardening Advice

Manuka is a hardy plant, but proper care will help it thrive.

Sunlight

Prefers full sun but can tolerate partial shade. Reduced sunlight may result in fewer flowers.

Watering

Drought-tolerant once established. For potted plants, water thoroughly when the soil surface dries out. Garden-planted Manuka usually requires little watering except during prolonged dry spells.

Soil

Grows best in well-drained soil. For clay-heavy soil, mix in sand or compost to improve drainage.

Fertilizer

Apply slow-release fertilizer in the growing season (spring–summer) to encourage flowering. Avoid over-fertilizing.

Pruning

Light pruning after flowering helps maintain shape and encourages healthy growth. Removing crowded branches improves air circulation and prevents pests.

Cold Resistance

Prefers warm climates but can withstand mild frosts. In colder regions, provide winter protection, such as mulch at the base. Potted plants can be moved indoors to a sunny location.
