Podocarpus acutifolius is a podocarp shrub to small tree with narrow leaves, found in lowland to montane habitats. It provides structure and evergreen cover in mixed native plantings.
Identification
Narrow, acutely tipped leaves arranged spirally; dioecious with male cones and fleshy female receptacles bearing seeds (typical of podocarps). Compare leaf size and rigidity versus allied species such as P. nivalis and P. hallii .

Habitat
Natural Distribution
Endemic to the South Island, mostly west from the Buller catchment south to Martins Bay. Found on river flats, active and abandoned channels, forest margins and open shrublands, often forming dense thickets on alluvium where periodic disturbance maintains open light.
Conservation Status
Current Threats and Protection
Not Threatened nationally. Site‑level pressures include browsing and loss or confinement of river processes. Maintaining functioning floodplains and controlling weeds support natural regeneration and thicket dynamics.
How to Grow
Cultivation Requirements
Needle-leaved Totara thrives in full sun to light shade and prefers cool, free-draining soils. It is important to water regularly during dry spells to ensure establishment, though mature plants require minimal pruning beyond basic form maintenance. This species adapts well to various conditions within its natural range.
Planting Guide
Best Planting Practices
Plant in full sun to light shade into free‑draining, gritty or stony loams. Water to establish and mulch to moderate temperature swings; avoid waterlogged depressions. Space plants with allowance for suckering and the multi‑stemmed habit typical of this tōtara.
Ecology
Provides evergreen cover and structure along braided rivers and terraces. Receptacles and seeds feed birds; dense thickets offer shelter for fauna and filter flood silts, stabilising substrates while allowing native succession to proceed.
Uses
Traditional and Modern Applications
Useful as a tough, wind‑tolerant native for shelterbelts and riparian plantings where a fine‑textured podocarp look is desired. In gardens, combine with divaricates and tussocks for Westland‑inspired plantings that read well year‑round.
Landscaping Ideas
Pair with other podocarps (Hall’s tōtara, mountain tōtara) and wind‑tough broadleaf evergreens to create layered, Westland‑style shelterbelts. Its fine texture contrasts strongly with bold leaves and grasses, and the multi‑stem habit reads naturally in riparian‑themed gardens.
Seasonal Care
Year-Round Maintenance
Spring: check stakes, top‑dress and mulch. Summer: water during extended drought on light soils. Autumn: tidy damaged shoots and assess spacing. Winter: avoid waterlogging and heavy cuts during severe cold.
Pruning
Pruning Techniques
Prune lightly to guide form; avoid cutting hard into mature, leafless wood. Selective thinning maintains a layered, multi‑stem habit while preserving shelter value.
How to Grow Needle-leaved Totara
From Seed
Propagation of Podocarpus acutifolius from fresh seed is a viable method. Collect seeds in autumn to winter, once the fleshy receptacle turns red and mature. Clean the fleshy receptacle from the seed thoroughly, as this can inhibit germination. Sow fresh, cleaned seeds onto a well-drained seed-raising mix, lightly covering them. Podocarp seeds often have protracted germination, so patience is key; it can take several months to over a year for seedlings to emerge. Maintain consistent moisture and cool temperatures (around 10-15°C or 50-60°F) in a protected environment. Once seedlings are robust enough to handle, prick them out into individual pots and grow them on in a sheltered, cool, bright location until strong enough for planting out.
From Cuttings
Podocarpus acutifolius can be propagated from semi-hardwood cuttings, though rooting can be slow and sometimes challenging. Take firm, healthy stem segments, about 10-15 cm long, in late summer or early autumn. Remove the lower leaves and lightly wound the base of the cutting before dipping it in a rooting hormone to encourage root development. Insert the cuttings into a free-draining rooting medium such as a mix of sand and perlite. Provide high humidity around the cuttings, either by placing them in a propagation chamber or covering them with a plastic bag, and ensure consistent moisture in the rooting medium. Provide bottom heat (around 18-24°C or 65-75°F) if possible. Keep in a bright location out of direct sunlight. Rooting can take several months. Once rooted, gradually acclimatize plants to ambient conditions before potting up.
General Cultivation
Needle-leaved Totara is a hardy podocarp shrub to small tree that provides structure and evergreen cover in mixed native plantings, particularly in lowland to montane habitats. It prefers sun to light shade and cool, free-draining soils. Plant in full sun to light shade into free-draining, gritty or stony loams. Water to establish and mulch to moderate temperature swings; avoid waterlogged depressions, especially in winter. Water in dry spells to establish; thereafter, it is moderately drought-tolerant but benefits from occasional watering during extended dry periods. Minimal pruning is needed beyond form maintenance. Prune lightly to guide form; avoid cutting hard into mature, leafless wood. This species often forms dense thickets on alluvium where periodic disturbance maintains open light.
Pests and Diseases
Common Problems and Solutions
Generally resilient; ensure drainage to prevent root stress. In sheltered, still corners scale can arise-improve airflow and wash foliage if needed. Protect young plants from browsing in restoration sites.
Cultural Significance
Traditional Uses and Values
Westland tōtara contributes to the character of South Island river‑terrace ecosystems. Using eco‑sourced plants in riparian projects sustains local whakapapa and supports resilient, functioning native communities.
Bonus Tip
Expert Growing Advice
To encourage its naturally dense, multi-stemmed habit, allow Podocarpus acutifolius to develop with minimal pruning. Its resilience in Westland's river-terrace ecosystems means it thrives when planted in cool, free-draining sites with occasional dry spells, rather than requiring intensive care.
