Is my black maple dying or just stressed?
Classic maple decline runs marginal leaf scorch, then early fall color in August, then undersized leaves and progressive twig dieback, and it can play out over anywhere from three to fifteen years, with road salt the usual driver on street-side trees. Scorch by itself in a dry August is stress; scorch plus premature color plus dead twig tips in the upper crown is decline already several years underway.
Why black maple ends up on a quote here
Effectively a sugar maple variant — often classified as Acer saccharum ssp. nigrum — told apart by darker, droopier, mostly three-lobed leaves and small leafy stipules at the base of the leaf stem. It matters practically because it handles heavy, moist clay better than true sugar maple, yet it is routinely sold, mapped and invoiced as sugar maple, so what a homeowner believes they own often is not what is in the yard.
