Propagation
Sow fresh seed when available during mid-summer in a well-drained media and keep moist and warm.
Take soft tip cuttings without 'Heels' during a late summer and a place in a plastic bag with moist sphagnum moss and then placed in a refrigerator at a temperature of 4°C for up to 8-weeks prior to placing in a pot.  Cuttings respond to bottom heat and misting.
Branches can also be layered in situ.

Note:
The timber is traditionally used for boat building, joinery, turnery and carving but supply is now restricted as remaining stands are protected. From: pollen collected from the sediment of Lake Johnstone on Mt. Read indicate that a stand of the male clones has had a continuous presence for over 10,000 years and fallen logs that are over 200 years old are still milled.
This tree can form thickets by vegetatively reproducing where the branches touch the ground and are covered, forming roots.

Botanic information
Leaf: The bright green scale adult leaves are up to 2 mm (2/16 in) long and are closely pressed spirally along the stems. The upper surface is keeled and the apex is obtuse to acute. The seedling leaves are linear with a pungent apex and are arranged spirally.

Flower: The tree is dioecious with male and female strobili found on separate trees. The yellowish cylindrical male pollen cones are up to 5 mm (⅛ in) long and have 12-15 microsporangia. They appear terminally on twigs and the small female seed cone is berry-like with 4-8 small lax scales with a single ovule in a cup-like aril.

Fruit: The very small female seed cone persists on plant and matures somewhat fleshy in 6-8 months producing a single seed that is up to 2.5 mm long and appear on one or more of the scales. The small seeds are viable but the plant is commonly reproduced vegetatively.
