Mimosa trees are fast growing and can reach heights of 20 to 40 feet. However, they also have relatively short lives. If you live in an area with harsh winters, your mimosa tree will most likely not survive the winter. Their fragrant and attractive flowers and easy care make a lot of people choose to grow mimosa trees.
Buy a young tree or start with a seed pod you can get from anyone who has a mimosa tree.
Plant the tree in full sun. If you live in a cold climate, it is best to plant your mimosa tree near a wall to help it to retain heat.
Water your mimosa tree only during very dry periods. It is not necessary to water it if you are getting normal rain levels.
Remove dead branches as they occur to keep the tree healthy.
Weed out baby trees that develop from seed pods. Mimosa trees can be very intrusive, making hundreds of babies which grow from their dropped seed pods.
Fertilize your mimosa tree in the early spring before there are signs of new growth if you live in a milder climate and your tree has survived the winter. You also might want to fertilize the tree if you notice signs of leaves turning yellow. Yellowing leaves is an indication of a fungal disease. There is nothing you can do to save the tree from the disease, but fertilizer can prolong the life of the tree and slow down the progression of the disease.
