|---|---|
| Spread | 20-40 ft |
| Growth rate | Fast |
| USDA zones | 6-9 |

| Native range | Asia, from Iran to China and Japan. It was brought to the U.S. as an ornamental and has spread into the wild in many Southeastern and Mid-Atlantic states. |
| Roots | Shallow and spreading, and the tree can sprout from roots. Seeds in long pods can sprout in large numbers. |
| Wood | Light, soft and weak. It is a poor firewood and breaks easily. |
| Storm risk | highThe wood is weak and brittle, the crown is wide and flat, and the tree often has multiple stems. Branches break easily in wind, ice and heavy rain. Trees are also short-lived and often decayed. |
Typical ranges, not guarantees. Soil, water, space and care change how a tree grows. Storm risk is our general rating for the species, not an inspection.
For homeowners
Caring for a mimosa
Best time to prune
Remove dead or broken limbs in late winter. Keep any pruning light.
Avoid pruning
Do not rely on heavy pruning to control it. Cuts often trigger many weak sprouts. Many homeowners find removal to be the more practical choice.
More on timing: when to prune trees.
- Mimosa has pretty pink flowers in summer but is short-lived and weak-wooded.
- A fungal disease called mimosa wilt has killed many trees in the Southeast. Ask your county extension office about it.
- Seed pods drop and seedlings can pop up all over. Pull seedlings while they are small.
- Keep it away from houses, cars and play areas because branches break easily.
Safety first
Do not climb a tree or use a chainsaw on storm-loaded or broken wood. If a tree or limb is touching power lines, stay away and call the utility. If someone is in danger, call 911. For anything big, hire a local insured pro: read how to hire a tree service and is my tree dangerous?

For tree crews
Field notes: working on mimosa
- 1Expect weak unions and hidden decay. Test limbs before loading them.
- 2Plan for sprouts after removal. Stump grinding and a follow-up visit are often needed.
- 3Many multi-stem trees lean over fences and roofs, so plan rigging carefully.
- 4Seed pods and leaves add to cleanup volume.
Removal notes
Mimosa often sprouts from the stump and roots, so cutting alone usually does not stop it. Follow-up is typically needed, such as stump grinding and watching for new sprouts. Herbicide use should follow the product label and local rules. It is considered invasive in several states, so check local guidance.
Wood
Light, soft and weak. It is a poor firewood and breaks easily.

Mimosa: common questions
Is mimosa an invasive tree?
It is listed as invasive in several states, mostly in the Southeast and Mid-Atlantic. Check your state's official list or your county extension office for current guidance.
Why does my mimosa keep dying?
Mimosa is short-lived, and in many places a fungal wilt disease can kill it within a few years. A local arborist or extension agent can help confirm.
Why are there baby mimosas all over my yard?
The tree makes many seed pods and also sprouts from roots. Pulling or mowing seedlings early helps.
Is mimosa dangerous to keep near my house?
It can be. The wood is weak and branches may break in storms. Many people choose to remove it or keep it well away from structures.
Can I just cut it down?
You can, but it often resprouts. Plan for stump grinding or follow-up treatment, and ask a pro about the best method.
What can I plant instead?
Ask your county extension office for native or well-behaved options for your area, such as smaller flowering trees that match your zone and soil.
