Here are some tips from conifer expert Richard Bitner:

• The best time to plant conifers is spring or early fall, in well-drained soil.

• Site the conifer according to its growing conditions. Most prefer sun; a few tolerate shade.

• Dig a hole twice the size of the root ball, and plant your conifer at the level at which it was grown.

• Loosen the root ball before planting.

• Water frequently the first couple weeks. Once their roots have been established, they will rarely need water. Mulch to retain moisture, making sure the mulch is at least 6 inches from the trunk.

• Heed the plant's likely growth rate; use slow-growing cultivars for borders to avoid pruning.

• Spacing is critical. It's better to leave too much between plants than too little. And know where drain pipes empty. Keep plants at least 4 feet away from the house.
