Plant Mountain Tōtara during autumn or early spring when temperatures are cool and soil moisture is adequate. This hardy species establishes well when planted during optimal weather conditions.

Site Selection

Choose a site with:

  • Full sun exposure with excellent drainage
  • Sloping or elevated position that avoids water accumulation
  • Room for mature size (15m tall, 8m spread)
  • Exposure tolerance once established makes windy sites acceptable

Planting Procedure

  1. Dig hole 2-3 times wider than root ball, same depth
  2. Improve heavy soils with sand and gravel for drainage
  3. Position tree so root collar sits at natural soil level
  4. Backfill with improved soil mixture
  5. Water thoroughly to settle soil around roots
  6. Create shallow watering basin for establishment
  7. Apply organic mulch but keep clear of trunk

Initial Care

Provide regular watering during first 2-3 years until established. Mountain Tōtara becomes quite drought-tolerant and low-maintenance once mature root system develops.

Propagation Methods

From Seed

Mountain Tōtara propagation from the attractive red fruits:

  1. Collect ripe red fruits from female trees in autumn
  2. Remove fleshy red aril and clean seeds immediately
  3. Sow fresh seeds in well-drained seed mix at 5-8mm depth
  4. Maintain cool, moist conditions (16-20°C)
  5. Germination typically occurs over 8-14 weeks
  6. Keep seedlings in partial shade during first year
  7. Transplant when 15-20cm tall and well-established

Seedlings grow slowly initially but pick up pace after 3-4 years, reaching maturity in 20-30 years.

From Cuttings

Vegetative propagation preserves specific characteristics:

  1. Take semi-hardwood cuttings from healthy current year's growth
  2. Use rooting hormone and free-draining cutting mix
  3. Maintain humid conditions with good air circulation
  4. Rooting takes 4-8 months with moderate success rates
  5. Gradually acclimatize rooted cuttings to outdoor conditions

Plant Description

Physical Characteristics

Podocarpus species are characterized by their distinctive linear leaves, often with prominent midribs, and their unique cone structures modified into fleshy, bird-dispersed fruits rather than typical woody cones. Mature trees develop thick, often corky bark and impressive trunk diameters, with tōtara specimens reaching up to 3 meters across. The genus displays remarkable size diversity, from towering forest emergents to prostrate alpine shrubs.

Ecological Role

Environmental Impact

Podocarpus species serve as keystone species in New Zealand's forest ecosystems, often forming emergent canopy layers that support diverse communities of epiphytes, birds, and invertebrates. Their modified cone-fruits provide crucial food resources for native birds like bellbird, tūī, and kākā, which in turn disperse seeds throughout the forest. As large biomass dominants, they play vital roles in carbon sequestration and forest structural complexity.
