How to Grow Mimosa


The mimosa is a deciduous tree with fern-like foliage and white blooms. The blooms average two inches in diameter and appear in late April. The blooms last until July. It lives for 10 to 20 years. It is of the Leguminosae family and prefers USDA hardiness zones 6B through 9. The tree, because of its size, is often planted near decks or patios. It grows up to 25 feet in height and has a spread of up to 35 feet, and does not change color in the fall.

Step 1

Choose a spot that gets full sun (more than six hours of continuous sunlight per day). Dig a planting hole that is twice the size of the root ball and as deep as the rootball. Scarify the sides of the planting hole with a pitchfork.

Step 2

Center the mimosa in the planting hole. Fill the planting hole with water. Backfill with soil. The mimosa tolerates most types of soil, as long as the soil does not have an overabundance of salt. There is no need to amend the soil.

Step 3

Mulch the tree with at least three inches of compost or pulverized bark. Water with at least an inch of water. The mimosa tolerates drought, but has a deeper green color if the tree is watered with at least an inch of water each week.

Step 4

The mimosa tree drops blooms, leaves and seedpods throughout the year. To avoid pests and disease, remove and discard any fallen tree material as it falls. During storms, the mimosa, which has brittle wood, tends to break. Prune as needed for dead and decaying plant matter and remove any fallen branches as soon as possible.

Tips and Warnings

  • Surface roots tend to lift sidewalks, so if planting near a cement patio, do not plant it too close. Roots might also interfere with mowing. Watch for vascular wilt and treat as necessary when signs appear.
