Ginko Trees Provide Spectacular Yellow Color

Auburn, Dec. 7---Have you noticed the spectacular yellow color of ginkgo tree leaves this fall? The ginkgo tree is native Southeast China but grows well throughout Alabama.

If you are unsure what a ginkgo tree looks like, look for trees with fan-shaped leaves that are a brilliant yellow in the fall.

Ginkgo trees are deep-rooted and can grow 60 to 80 feet high, says Dr. Dave Williams, Extension horticulturist. However, they are slow-growing trees. The deep roots allow it to grow even in a dry site. The trees have no significant pest problems and can be planted in any soil pH commonly found in Alabama.

Young trees sprout leaves along stiff branches. As the tree ages, the canopy will thicken. Ginkgo trees may have an upright shape or be broadly shaped. The tree's with age.

There is one drawback to the ginkgo trees, says Williams. The female ginkgo produces a fruit that has an awful odor. After the tree passes the juvenile stage (usually 15 to17 years old) it will produce fruit. It is at this point, when you learn whether your tree is male or female. However, if are interested in planting a ginkgo, there are male cultivars available. Male cultivars Saratoga and Autumn Gold have a broad form and Princeton Sentry has an upright form.

You can plant container-grown ginkgo trees at any time. Fall is the best time to plant ginkgo or any tree. If you plant in the summer, be sure to keep it watered.
