How to Start Mimosa Trees


Mimosa trees originated in China and gained popularity in the U.S. during the 18th century. Appreciated for its ornamental attributes, the mimosa tree provides fragrant flowers to many landscape settings. Mimosa trees grow rapidly, quickly filling in bare areas and providing stability to eroding soils. This mildly invasive tree grows readily from planted seeds.

Step 1

Gather seed pods from a mature mimosa tree. Seeds pods begin to appear after the blossoms wilt. Check for readiness by shaking the seed pod. If you hear a rattling noise within, the pods are ready to pluck from the tree. Break open the seed pods and remove the individual seeds. Toss away any seeds that show signs of damage.

Step 2

Stratify your mimosa seeds to mimic conditions found in nature. Like many seeds, mimosa tree seeds require a dormant period to encourage germination. Wrap your mimosa seeds in a damp paper towel and cover it with a piece of plastic wrap to hold in moisture. Place the seeds in your refrigerator for three to four months. Soften the hard, outer casing of mimosa seeds by soaking them for 24 hours in warm water. This encourages healthy germination and shortens the sprouting time. Handle soaked seeds with care.

Step 3

Plant your prepared seeds in average potting soil. Add a little peat moss and vermiculite to retain a high level of moisture during germination. Use small seed pots made from biodegradable materials to start your seeds. Fill the seed pots with your potting soil to a level just below the rim of the pots. Press the seeds into the soil and cover them with a small amount of potting soil. Gently press the surface of the soil to remove large air pockets. Water the seeds well and place the pot in a warm location. Avoid placing mimosa pots in bright sunlight during the germination process. Keep the soil slightly moist while the seedlings emerge. Move the pots to a sunny location after shoots appear above the soil.

Step 4

Transplant your mimosa seedlings into well-drained soil. Dig a hole large enough to provide adequate space for the entire pot. Place the biodegradable pot in the ground, keeping the top of the soil in the pot level with the surrounding ground. Water after planting and provide protection from strong winds during the first season.
