Weinmannia racemosa (Kamahi)

Kāmahi, Kamahi Tree

Weinmannia racemosa, commonly known as Kamahi, is a versatile and widespread native tree found throughout New Zealand’s forests. It typically grows 8–15 metres tall and features leathery, toothed leaves and distinctive spiked clusters of small white flowers in spring and summer. Kamahi is tolerant of a wide range of conditions, thriving in both lowland and montane environments. Its dense foliage and fast growth make it ideal for revegetation, shelter planting, and enhancing native biodiversity.

Growing Weinmannia racemosa Successfully in NZ

Weinmannia racemosa (Kamahi) is well-suited to New Zealand conditions and is relatively easy to grow. It prefers a sheltered position with moist, well-drained soil and tolerates both full sun and partial shade. Kamahi is hardy and adaptable, thriving in a range of soil types, including clay. It benefits from mulching to retain soil moisture and suppress weeds. Regular watering during dry spells will help establish young trees more quickly.

Weinmannia racemosa Care Tips

Kamahi requires minimal maintenance once established. Water young plants regularly during dry periods to help them establish a strong root system. Apply mulch around the base to retain moisture and suppress weeds, keeping it clear of the trunk. Pruning is rarely needed but can be done to shape the tree or remove dead stems. Kamahi is generally pest-resistant and hardy, making it a low-fuss option for native or revegetation plantings.

Plant Size and Spacing

Weinmannia racemosa (Kamahi) typically grows 8–15 metres tall and up to 5 metres wide, though it can reach greater heights in optimal conditions. When planting for revegetation or shelter purposes, space trees approximately 2–3 metres apart to allow for natural canopy development. When grown as a specimen or in mixed native plantings, a wider spacing of 3–4 metres is recommended.
