Amur Privet Privacy Hedge

I live in the Fargo-Moorhead Area and would like to create a natural privacy fence. I am looking for something that is quick growing. Popular suggestions include Green Thuja and Privet. The Green Thuja is considered hardy only up zone 5, but I found sites that suggest it would survive our local winters. Different types of Privet appear to be hardy in our zone, but I don't see many Privet hedges in the area. I was wondering if you had any suggestions to what type of Privet would do best in this area.

Thanks for your advice!

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

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.
