My blue spruces seem to be dying from the bottom. Branches and needles falling. Is it a fungus? I read about Rhizosphaera Needle Cast and it seems like a good description of what we are seeing. This is the 2nd year we've noticed them looking sick. Is there anything we can do? We have a well so I was hesitant to spray fungicide. Any advice would be greatly appreciated

Blue spruce trees are prone to a number of diseases you mention one, rhizosphaeria needle cast but there is also cytospora canker. Cytospora canker also causes dieback from the bottom up.

You should contact a certified arborist for an onsite evaluation of the trees. They should be able to diagnose the problem and submit a treatment plan. To find a certified arborist go to the following websites, http://www.goodtreecare.com/search/index.cfm and www.treesaregood.org
