I am thinking about planting this type of Tree. Is it safe from all the other firs ,pines that are dying? Can this tree be planted about 2 to 3 feet off the edge of a concrete driveway? I am concerned about the reflection of the sun, Or have you any recommendations on what might be a good tree to plant? Will be planting 5 or 6 trees. Thank You Dave

Colorado blue spruce is susceptible to a cluster of diseases that make the tree unsightly after a dozen or so years. These diseases include Rhizosphaera needle cast and Cytospora canker. Our climate is simply too humid for these trees. We do not recommend planting them.

'Fat Albert' is a dwarf cultivar of CBS and is susceptible to the same diseases as CBS. However, we have heard anecdotal information that these diseases are not as serious in the dwarf cultivars. Furthermore, if the trees become unsightly after 15 years, the cost of removing them is not as great as for a full sized tree. But don't expect a disease-free tree. Read here:

You might want to consider another hedge conifer, such as arborvitae. Read here:

Thank You for the information. I just had 5 pines that were planted 25 years ago removed as the disease caught up with them,excellent point about smaller trees if removal is required. Again Thank You. I am going to use the criteria you sent as my guide. Dave Emmons
