Avoid planting in poorly drained or alkaline soils.
Maples other than Norway maple are sensitive to deicing salt.
Maples perform better in lawn or park settings and in groups,
rather than as single specimens in fully exposed boulevards.
Planting with the root collar at ground line is important to see
and treat girdling root syndrome.
