How to Grow Mimosa Seeds
Propagation of mimosa is by sprig and seed planting. There are two distinct types of mimosa, a fast spreading ground cover and a tree variety. The tree species can grow to a mature height of 20 to 40 feet. The ground cover can spread to a full size of 200 to 300 square feet in a single growing season. The rate of growth depends on climate conditions. Both species produce a seed pod that has five to 10 seeds in each light brown pod. The seeds must be scarified to germinate in the first year of planting. Does this Spark an idea?

Check soil moisture every two weeks. Insert your finger into the soil 1 inch deep. If dry, add 1 cup of water. Leave the plastic food wrap in place until the plants emerge from the soil.

Tips & Warnings
Mimosa will grow in most types of soil and will soon overtake the area. Prepare the permanent planting location by removing all weeds, roots and rocks. Minimal cultivation is required for the transplant bed. Keep the seedlings moist for the first year of growth.
Some varieties of mimosa may be considered an invasive pest plant in some areas. Check with your local agricultural extension service before planting the seeds.
