Mimosa Plant Care

Overview

There are many different varieties of mimosa. Different varieties are suited to different climate zones. However, care of the plants is similar. Mimosa plants feature compound, feather-like leaves and flowers that look like spiky pompoms. Some varieties, like the Mimosa pudica, close their leaves when touched. Caring for an established mimosa is not difficult.

Light

Avoid planting trees or constructing buildings that will shade your mimosa. Mimosa does best in full sun. Mimosa is generally suitable, according to the University of Miami, to medium light conditions or better. Some varieties, however, can also do well in partial sun. Most mimosa will not grow well in shade.

Soil

Mimosa will tolerate poor soils. Mimosa are able to take nitrogen from the air, making them uniquely suited to very poor soils, and will grow in sandy soils or soils with high clay content. However, they do best in moderately fertile loamy soil. Mimosa requires soils that drain well.

Water

Water your mimosa liberally during the growing season. Several inches of water should be sufficient. If you have gotten a lot of rain, you can water a little less. Water the tree or bush very little during the winter, but do not completely withhold water. A couple of inches per week should be sufficient. Mimosa is very sensitive to drought.

Fertilization

Mimosa can benefit from fertilization. Fertilizing with a very low rate of controlled-release fertilizer that contains no phosphorus can help to increase flowering. Do not add phosphorus fertilizer to the soil around your mimosa unless a soil tests indicates a deficiency.

Pruning

You may need to prune your mimosa tree or bush. Because it grows very quickly, branches can sometimes need to be trimmed every year. Branches can become heavy. If they grow over a walkway or driveway, they can droop down, blocking the path. Prune the tree by starting from the bottom up and working from the inside out to create the desired shape. Hand shears will work on branches about 1/2 inch in diameter, but you may need saws for thicker branches.
