Space plants to allow for ultimate growth (though most conifers can readily be transplanted later.) Choose a location that offers full sun (golden varieties and some blue-green varieties might prefer light shade and a location that is somewhat sheltered), and a soil that is well-drained but with plenty of organic matter mixed in.
Prepare an ample hole, set plant so the soil level of the root ball is level with the surrounding soil, fill in the hole, firm soil well and water in thoroughly. Mulching is strongly recommended.
Water during extended periods of drought, especially with container specimens. Prune at least once a year, and more where appropriate to develop and maintain shape. Conifers may be pruned at any time of year, except in late summer as this will induce new growth that will not have the opportunity to harden before winter.
