Species Requirements Distribution Range:
Zone: 3 to 8 Habitat:
- Extreme SE. Manitoba east to Nova Scotia, south to North Carolina, and west to E. Kansas.
Hardwood forests, especially in the Beech-Maple climax community. Grows in moist soils of uplands and valleys, sometimes in pure stands. Preferred Light:
Full sun/partial shade. Tolerance to Salt:
- Grow best in full sun.
Grows best if planted in a fertile, moist, and well-drained soil region. Sandy or Loam. pH Range: 3.7 to 6.5
Care Common Diseases:
- Leaf spot.
- Leaf blister.
- Bull's-eye spot.
- Eutypella canker.
- Truk decay.
- Maple leaf cutter.

- Maple phenacoccus.
- Sugar maple borer.
- Does not tolerate air pollution; susceptibility to gas and smoke damage makes Sugar Maples less suitable for city conditions than Norway and Red Maples.
- Intolerant of salt that is used to melt snow.
- Leaf scorch in excessive droughts.
- Verticillium wilt can be a problem.
- Birds and rodents eat the seeds.
- Deer, squirrels, porcupine and other mammals browse the twigs, buds and bark.
