My wife and I bought a dwarf Japanese maple last year and this was its first winter. We live in the Eastern portion of Washington state. Some of the branches appear to be a light gray and some of them are the maroon color associated with Japanese maples. I don’t see leaf buds yet but have noticed what appears to be a split on the southeast side of the tree. I’ve done some reading on this. Should I bind the trunk or monitor it as we get into the warmer part of spring? I have pictures but there appears to be no way of attaching them to this correspondence.
