Mimosa trees are native to Asia, but they were introduced into the U.S. in the 18th century as an ornamental plant. With their fan-like leaves and pink pom-pom flowers, they are a lovely tree to look at. Mimosa trees also grow easily in many parts of the U.S., as they require very little care. However, they are susceptible to certain diseases, are short-lived and can become an invasive species if planted in the wrong area.
Plant your mimosa in a large, well-lit area. Mimosas need a lot of sunshine in which to flourish. Make sure the tree will be well away from flower beds and other loose soil. Allow at least 30 feet around the mimosa so it has room to spread. If you are limited on space, mimosas can be grown in large planters and kept pruned.
Dig a hole for the mimosa tree. Dig at least 2-3 feet deep so the roots can take hold. If you are planting a seed or seed pod, dig a hole at least 10 inches deep. Make sure the area around the mimosa is covered in grass. This makes it easier to clean up the seed pods and prevent distribution of the seeds to unwanted areas.
Place the mimosa tree or seed in the hole. Cover with soil until the hole is full.
Water the mimosa two to three times a week. Allow the hose to dribble on the mimosa for about 10 minutes, soaking into the soil. Over-watering will kill the mimosa.
Prune the mimosa once every season. Prune any low lying branches so you can walk under your mimosa. Also prune any over-reaching or dead branches as they occur. They can snap off in high winds and damage property or people.
