How to Plant a Mimosa Tree Seed


The mimosa looks like a tropical tree, with its fluffy blossoms and feathery leaves. It grows quickly and just about anywhere, to the point it has been classified as an invasive tree in some states. It has been cultivated in the U.S. since the 1800s as an ornamental plant and adds visual interest and beauty to a landscape. You can start your own from seeds collected from a healthy tree.

Step 1

Remove the seeds of the mimosa tree from the pods, and place them in a heatproof container. Pour boiling water over the seeds to cover. This will help to scarify the seed coat or break it down, so the seed inside can germinate. Soak the seeds in the water for at least 24 hours, letting it come to room temperature.

Step 2

Prepare a planting pot by filling it with potting soil. It does not matter what kind, as the mimosa grows easily in many types of soil. Fill it within an inch of the top, and give it a good watering, until it drains from the bottom drainage holes.

Step 3

Plant the seeds in the pot, burying them about ½ inch into the soil. Push the soil over the top of them, and tamp it down slightly to make good soil contact between the soil and seed.

Step 4

Water the planted seeds lightly, and place in a sunny window or outside in a warm spot. They grow quickly and usually without any special care besides moist soil and sunshine. Transplant to a permanent home when about 6 inches tall, but be careful to keep the seedlings that emerge from the plentiful seeds under control, or you will quickly have a thicket.
