    From the city’s urban forestry & natural resources planning coordinator, Kerry Gray:

    It is not unusual to have frost cracks on sycamore, and the one pictured … is an old crack that has reopened during this very cold weather. The crack will close up again as temperatures warm up. Frost cracks are not known to be fatal, however, like any wound on a tree, it may provide an opening for insects/diseases.

    Gray also passed along some links:

    Any knowledge of what species this tree is?

    Trees can heal if such cracks are left alone to develop wound tissue. The antiquated practice of sealing with paint or putty has been documented to cause earlier death because of wood rotting fungi.

    Looks like a sycamore, and that’s what Kerry referred to in her message.

    Don’t do anything–it will heal itself
