How to Germinate a Mimosa Seed


Mimosas, often referred to as "Sensitives," have a unique characteristic: When the leaves of a mimosa plant are touched, they instantly close up. This novelty trait makes the mimosa a fun addition to any yard. While you can buy grown mimosa plants, it is usually cheaper to purchase the seeds and grow them yourself. The first step in starting a mimosa from seed is germination. These seeds are quick to germinate--germination can sometimes take as little as two days.

Step 1

Choose a spot in your yard that gets full sun. Add 1 inch of compost to the surface of the soil. Mix 2 inches of soil with the 1 inch of compost together with a tiller or shovel.

Step 2

Put the mimosa seeds in the bottom of an empty bowl. Slowly pour hot water into the bowl until it covers the seeds. Let the bowl sit overnight.

Step 3

Check the seeds the following day. Some of the seeds will be swollen while others remain the same size. Remove the swollen seeds, as these are ready to plant. Drain the water in the bowl and add more hot water to the other seeds and let them sit for an additional day.

Step 4

Drop three seeds in the same spot on the soil. Press them into the ground ¼ inch deep and lightly cover them with soil. Plant all additional seeds at least 5 feet apart as the shrubs can grow quite large. It's best to plant at least three seeds per spot, as some seeds may not germinate successfully. Repeat the same process for additional seeds the following day.

Step 5

Keep the soil moist until the seeds germinate. Do not let the soil become soggy or dry at any point. Mimosa seeds typically germinate within three days.
