Care
Watering
Keep the soil regularly moist, especially during the first three years after planting. Once established, water during prolonged dry spells, particularly in summer. Avoid waterlogging which can promote root rot. Mulching helps retain soil moisture.
Light exposure
Choose a sunny to partially shaded position. This species naturally grows at forest edges and tolerates light shade well. In hot regions, some protection from hot afternoons can be beneficial.
Pruning and trimming
Lightly prune dead or poorly oriented branches in late winter or early spring. Dacrydium cupressinum doesn't require heavy pruning; preserve its natural, slender pyramidal shape. Avoid drastic cuts which could weaken the tree.
Fertilization
Apply balanced fertilizer in spring for young growing trees. Once established, the tree has moderate needs. An application of compost or well-decomposed organic matter every two years is generally sufficient.
Soil and drainage
Requires well-draining soil rich in organic matter. Incorporate compost or peat when planting to improve structure. This species dislikes compacted soils and stagnant winter moisture.
Diseases and pests
Generally hardy against pests, but can be affected by root rot if drainage is poor. Monitor for fungal pathogens in very humid and poorly ventilated environments. Good air circulation and well-draining soil prevent most problems.
Did you know?
Dacrydium cupressinum, called 'Rimu' by the Maori, was used by New Zealand's first inhabitants to build their dwellings and canoes thanks to its durable and beautiful wood. This majestic tree can live for several centuries, with some ancient specimens becoming important natural monuments in New Zealand's forests. Its tiny leaves give it a delicate and airy silhouette, contrasting with the remarkable strength of its trunk.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
