Dwarf Alberta Spruce - Knowledgebase Question

I purchased 2 Dwarf Alberta Spruce about 3 years ago. This spring one started turning brown and dropping needles. It has very little green left and I just noticed a spot on the other one doing the same thing. Any ideas?

The browning could indicate a population of spidermites or other insects or it might indicate water stress. Carefully inspect your spruces for insects. Spidermites are tiny and hard to detect but they leave webbing between the needles and the branches. Spots on the needles indicate a fungal disease such as needle cast. Poorly draining soils can cause browning needles, as well. Hope you can determine and treat the problem before you lose your other spruces!
