The mimosa tree, also known as the silk tree, is a tree that grows naturally from the Middle East to Japan. Depending on whom you ask, the tree is either an attractive ornamental or an invasive nuisance. Although the tree produces dappled shade, fern-like leaves and feathery foliage in shades that range from salmon to purple, the seeds spread easily and the tree is prone to disease and breaking. The tree grows well in many types of soil from loam to clay. Trees that are cut down produce suckers that come back repeatedly. Because of this, getting rid of a mimosas once you have them is not easy.
Cutting Mimosas Down
Cut down trees at ground level with a chainsaw before they flower to prevent the distribution of seeds.
Paint the stump of your mimosa tree with a broad-spectrum herbicide containing glysophate in an effort to kill the roots.
Observe the area where the tree was cut down and cut down any saplings that spring up. Treat the cut sumps of these saplings with herbicide as well.
Girdling Mimosa Trees
Remove the bark of the tree in a 3-inch ring around the base of the tree. Allow the tree to die completely. Dead trees will lose all their leaves. If you peel the bark back, the trunk of the tree will appear gray.
Cut the tree down at ground level with a chainsaw.
Observe the ground around the tree for any new saplings that the roots send up.
Water the ground around these saplings to loosen the soil.
Pull the saplings out of the ground to pull up the roots of the plants with them.
