In 1745, the mimosa tree was introduced to the United States from China. The small tree become widely cultivated by gardeners as a specimen tree for its fragrant flowers. The mimosa tree is often called the silk tree. It is easy to grow and establish. This ease-of-growth has earned it the classification of a category two invasive plant by Florida's Exotic Pest Plant Council. The tree easily escapes cultivation and flourishes in the wild and alongside the roads. The tree can easily grow to a height of 40 feet. Seeds are spread by animal indigestion and excretion or from tree runners. Seeds can lay dormant for years before reproduction.
Plant your mimosa tree in a sunny location with well-drained soil. The ideal spot should offer six or more hours of sun per day. Plant the tree away from houses or outbuildings because the long seed pods can be abundant and difficult to clean up. Locate the tree in an area with other large trees, fence line or strong vegetation to offer protection from strong winds. The mimosa tree has brittle limbs so it can sustain a great deal of wind damage in a severe storm.
Cultivate a mimosa tree from a seed in a mimosa seed pod. Plant the seed in a plant-starter soil approximately 1/2 inch deep. Set the container with the seed in a sunny window and await germination. Keep the soil moist, but not water logged. Cultivate the seed indoors until it's firmly established, then transplant outside.
Water your mimosa tree sparingly, as they require very little water. Average rainfall is normally the only water source they require, unless there are extreme-drought conditions.
Prune your mimosa tree in the spring. Remove any dead or broken branches using a pair of loppers. Trim any branches that are growing wayward. The mimosa handles pruning well when required, but also does fine with no pruning.
Fertilize your mimosa tree in the early spring using a well-rounded, 10-10-10 fertilizer. Spread 1 cup around the base of the tree and water until the fertilizer is absorbed.
