Norway Spruce in ND

I am located in the Bismarck, ND area and am planning to plant numerous trees on a 2.5 acre rural residential lot. The Norway Spruce looks like a good candidate on paper, however I have heard of instances in ND where planting this tree wasn't successful. Can you give any past history on success and details on how to be successful in establishing the Norway Spruce in ND. Thanks

Juniper

These junipers were planed in 1970 and the lower branches are dead and have been pruned. I found these chanker on two of the trees as shown. Enjoy the privacy afforded the row of junipers. How should I care for these trees

Mildew in Ninebark 'Diablo' shrub

My 12- to 15-year-old Diablo Ninebark shrubs have had downy mildew for 3 or 4 years. Each year I prune branches out that have mildew. I disinfect my pruners between cuts, clean up as much as I can around the bushes, and throw all the leaves and branches in the garbage. The problem becomes more severe each year. These bushes get lots of airflow around and through them. I'm keeping the centers open for air flow.

I am wondering if I can give the bushes a hard pruning this spring before they leaf out, and if that will help control the mildew. How far down can I prune them -- is a foot from the ground too much? Or would I be better trying to control the problem with a fungicide. My thought is that if I get rid of as much of the mildew as I can, I would have an easier time controlling it with a fungicide. I have not yet used a fungicide.
