Sweet gum is a deciduous Shade tree than can easily exceed 100 feet in height, often with a spread of 35 to 50 feet. The tree is symmetrical, oblong and rounded once mature, and is a medium to fast grower. It is found in the eastern united states, also in the mountains of Mexico and Guatemala. It can grow in full sun or filtered shade, but grows best on moist, well drained sites.
Sweetgum trees are used for veneer, furniture, and pulpwood for quality papers. It produces a dark purple to reddish brown hardwood, which has been tagged Italian mahogany or Satin walnut. It is also planted ornamentally because of it's unusual brilliant red foliage.

Hardiness and sensitivities
The sweet gum tree has moderate drought and aerosol salt tolerances and It is cold hardy to zone five. Usually it is not bothered by disease, and Pest do not usually affect its long term health. However, some pests that may start to inhabit a tree include bagworms, fall webworms, leaf miners, Cottony cushion scale, walnut scale, sweet gum scale, and tent caterpillars.
One of the few diseases that may affect sweet gum is canker disease. These diseases cause areas around the trunk to become sunken and cause the tree to "bleed." There is no chemical control for these diseases, and severely infected trees will probably die.
Sometimes leaf spots may cause defoliation, but usually they are not too serious. Proper tree maintenance and care will help ensure a healthy plant.
