How to Grow a Golden Rain Tree

The deciduous golden rain tree (Koelreuteria paniculata) grows to a height of 30 to 40 feet. The compound leaves of the tree measure up to 18 inches long and have 17 leaflets. In spring, leaves have a pinkish cast, then turn green in summer. From August to September the tree produces an abundance of yellow flowers that appear in panicles that measure up to 20 inches in length. Following flowering seed pods appear in shades of reddish-purple. Each seed pod measures 2 inches long and is striking against the tree's yellow autumn foliage.

  Clear grass and rocks from a site in full sunlight for maximum blossom production. The golden rain tree prefers a planting location with well-draining soil. It can tolerate a wide range of soil types, such as acidic and alkaline soils.

• 2

  Dig a hole twice as large as the tree's root system. Tamp the soil down around the tree's roots to remove all air pockets. Apply a layer of mulch 2 to 3 inches deep around the base of the tree to help prevent weed growth and keep the new tree's root system moist.

• 3

  Water the golden rain tree weekly. Allow the water to slowly trickle around the tree's base to slowly water its root system deeply.

• 4

  Fertilize the golden rain tree in March, May and July. Use a a well-balanced fertilizer such as a 10-10-10 or 8-8-8 -- the numbers indicate the percentage of nitrogen, phosphorus and potassium in the fertilizer.

  Prune away dead branches or branches that cross and touch during the winter months when the tree is dormant. Discard the branches and rake up any leaf debris from under the tree to help prevent fungal diseases from occurring.
