Propagation
Prior to sowing stratify fresh seeds at 5º C (41ºF) for 14 days.
Note: 'Aurea' is a grafted during early spring on 2 to 3 year old understocks.

Culture
This is a large tree and care should be taken when selecting its position as the roots are strong and can damage drainage lines and building foundations.

General pruning information
Cedars are easily transplanted when young. They normally require little pruning and care should be taken not to cut or damage the leading shoot, as this will ruin the habit of the tree. Long horizontal branches that collect snow may be cut back to reduce the load as heavy branches may snap off. 

Botanic information
Leaf: The acicular leaves are 4-sided with lines of stomatous on each side and appear on a short spur branch in whorls of 15 to 25. The scattered needles also occur in clusters on the current season's growth and are glaucous green when young maturing to dark green.

Flower: The upright male finger-like strobili are up to 75mm (3in) long and 17mm (⅝ in) wide, pinkish yellow when ripe and shedding pollen in autumn. The female cones are greenish, erect up to 15mm (¾in) high and appear in the upper part of tree in large numbers.

Fruit: Young female cones are violet ripening to brown, and up to 120mm (4½in) x 60mm (2½in), in a barrel-shape with a flat top. They mature after 2 years then disintegrate, leaving columella stumps. The seed is triangular and winged.
