Tree & Plant Care

Best in full sun, adaptable to many soil types as long as they are moist and well-drained.
The shallow, spreading root system benefits from a 3-4” layer of organic mulch.
Spruces require very little pruning.
All evergreens experience seasonal needle fall in autumn.  On spruces this shows up as brown needles on the interior of the tree.

Disease, pests, and problems

Needle cast, cankers, bagworms and mites are possible problems.
