Littlehawk ... I certainly cannot speak with authority to your local region and species. But, as you've described it, it sounds like a lack of water problem. I had it here last Summer. The condition, over here, was temporary and not fatal. I suspect that most any gardening center, or State Agriculural Centre (Canadian spelling ... hee hee) might be very willing to give you guidelines. You could always put a slow running hose at the root ball and let it go for a few days and see if it makes the tree smile! CHEERS, Bob
