Answer: This might be due to winter stress given the unusual winter we had including the severely dry weather. And/or it might be due to an insect or disease problem such as a mite infestation. I would suggest you work with your county extension to determine what caused the discoloring and defoliation and based on knowing that, determine how to proceed. If it is something that requires a chemical control, they will have the most up to date information on what to use and how/when is best to use it. They may appreciate a photo of the overall plant showing the pattern of where the damage is occurring, as well as closeups of the affected foliage. Do not delay in doing this because bare spots on spruce generally do not grow back, so the plants will become increasingly disfigured the further the problem progresses. Good luck with your dwarf Albertas!
