Columnar Norway Maple

Posted by Ralph Higgs , Aug 13,2005,02:03       Forum

We planted a very healty looking 7ft columar norway maple in full leaf about 60 days ago. We follwoed the exact instructions from the nursery for planting. For 2+ weeks the leaves remained fine and healty looking. Then they started to turn brown in colour starting mainly from the edges inward. They have continued to darken, shrivel up and now the tree is 1/2 leafless and the rest of the leaves are soon to fall. I have been told unofficially by 2 people it looks like "rust".
Tree branches look normal. Water to roots always available so drying out is not the problem. We live in a very hot dry summer climate (37+C not uncommon)

Any ideas what to do if it is "rust" as I can't find any exact information on maple rust.
