Formosa Sweetgum has a wide, pyramidal shape when young but eventually grows to a rounded or irregular form, reaching 40 to 60 feet in height with a 35 to 45-foot spread. Young specimens may vary in form and be somewhat irregular.
The large, three-lobed leaves, purplish-red when young, are dark green through the growing season and in fall turn a beautiful yellow-red color in the south or red in the north. Branches are covered with characteristic corky projections. Formosa Sweetgum makes a nice park, campus or residential shade tree for large properties.
Be careful when locating Formosa Sweetgum as a street tree since its large, aggressive roots may eventually lift curbs and sidewalks. Plant trees 8 to 10 feet or more away.

| Germination | 1. Place seeds in moistened peat moss inside a plastic bag. Put the bag in the refrigerator or somewhere that temperatures remain 40 degrees Fahrenheit for 30 to 60 days. This will break the embyro's dormancy so the seed can germinate. 2. Sow the seeds on the surface of the soil in a 4-inch pot filled with potting soil. Press them down with your palm to make good contact with the soil. Water the pot and make certain it does not dry out. Place the pot in a well-lit area that is at least 60 degrees Fahrenheit. Faster germination will occur in temperatures above 60. 3. Fertilize the seedlings with a half dilution of seaweed fertilizer every other time you water. Commence this feeding process as soon as the seedlings have their first pair of true leaves. 4. Prepare a garden bed in spring. Dig in 3 to 5 inches of compost for nutrients, tilth and to help conserve water. Plant the seedling after you have hardened it off for a week. Install the plant at the same level it was growing in its pot. Mulch around the little tree but leave a clear space around the trunk of 1/2 inch. (info source: ehow.com) |
