Sick Willow Oak
I planted this willow oak last April/May and soon after I planted it I noticed a split in one of the main branches, so I waited until after the leaves dropped and pruned it/cut it off. This year it leafed out very late - about a month after my maples and other oaks did - and quite a few branched didn't leaf out at all, including the top. It also has put on very little growth, where my other trees have put on normal growth. It has developed an area of sponginess and discolored bark, but it doesn't look like what I have found in pictures on the Internet of canker. Anyone have any experience in this? Is this tree a goner or will it recover? I spent $200 on this guy last year and would hate to cut it down if it will make it.
