There are three main ways to buy Colorado blue spruce: balled and burlapped (B&B), container potted or bare-root. Colorado blue spruce is rarely sold bare-root unless as bulk seedlings. The type of container, or lack of it in the case of bare-root trees, helps determine when to plant the tree.

In areas with mild climates, like Southern California, Colorado blue spruce can be planted nearly year-round. Harsh winters and freezing weather limit planting times in certain areas. Use a freeze/frost map like NOAA's to estimate planting times in cold weather areas.

Balled and burlapped trees have diminished root systems. They need to be planted before canopy growth begins. Late winter (February) through early spring (March, April) is best. Planting in early fall is acceptable since leaf and shoot growth has slowed.

Potted Colorado blue spruces are either spruces dug up and potted for sale, or spruces that have been entirely container grown. Plant potted spruces in late spring through early fall. Spruces potted in field soil need early spring planting. Planting in spring through early fall is best for spruces grown in containers.
