Red maple is a widely adaptable large tree common to the woods of eastern North America. A red tinge can be found in its flowers, twigs, and seeds, but it is most notable for the scarlet of its leaves in fall. Red maple needs plenty of room for its dense, spreading root system. Fall color can be yellow rather than red, so select a cultivar bred for red fall color.

Tree & Plant Care
Chlorosis symptoms (pale green leaves with dark green veins) can be a problem in high pH soil and drought conditions.
Maples are considered 'bleeders' and are best pruned in early winter or during summer.
Although a good parkway or street tree, red maple does not tolerate heavy pollution.

Verticillium wilt (fungus) is a potential problem for maples; maple bladder gall, leaf hoppers
