Habitat: Hardy from zone 3 to 7, the Norway maple is widely planted in Iowa. It tolerates extremes in soil conditions, thriving in calcareous soils, sand and clay. This species adapts well to the nutrient-poor, compacted soils of cities, and tolerates ozone and sulfur dioxide pollution.
Diseases: Like most maples, it is rarely seriously damaged or killed by diseases or insect pests, but is susceptible to wilt, anthracnose, Verticillium wilt, leaf scorch, frost cracks and various minor insect pests. This species and the purple varieties are susceptible to sun scald and to scorching of the leaf margins in dry summers. When planted too deep, it is subject to the development of girdling roots.
