A mimosa tree is also called a silk tree and it’s known for its airy foliage and fragrant pink flowers. The scientific name of this plant is called Acacia dealbata and it belongs to the ‘Mimosaceae’ family.

This tree produces an influx of seed pods that are long and pealike.

The seeds are harvested during the autumn season and used for propagating new trees. Mimosa seeds are known for germinating quickly under warm conditions.

Here’s how you can grow one from its seed form:

  • Collect the tree pods and snip off the ends using heavy shears. The pods should be dry and dark to indicate its maturity.
  • Open the pods and proceed in shaking out the seeds. The seeds are flat and possess a dark-brown color.
  • Use a cloth bag or paper for storing the seeds. Keep them until the spring season in a dry and cool place.
  • Ensure that you aren’t using a plastic bag because it tends to trap moisture and causes the seeds to start rotting.
  • Now, it’s time for you to start preparing the seeds for sowing purposes after the final spring frost. Proceed in rubbing every seed’s end by using a nail filer.
  • You need to do this until a pale and tiny spot begins appearing on the hull. Start soaking the seeds in hot warm water for a day prior to sowing.
  • Take out biodegradable pots measuring up to 5 inches. Start individually filling in the pots using a mixture of half loam and half sand.
  • Ensure that this mixture is lightly moistened. Proceed in sowing a single seed in every pot up to a depth of 1-Inch.
  • Begin spreading sand all over the soil. You need to ensure that the layer of sand goes up to 1/4 inches.
  • Now, you need to place the pots outside against a west or south facing wall that receives full sunlight. If it’s cool weather, then give a bottom heat of 75 F, accompanied by a propagation mat.
  • If temperature during the daytime goes beyond 90 F, then give some light shade during midday.
  • The soil’s moisture level should also be monitored. Whenever 1/2 inch of the topsoil starts to dry out, ensure that you are watering it up to a depth of 2 inches.
  • Expect germination 1-3 weeks after you sow the seeds. The seedlings should be grown under the exact conditions as during the germination period.
  • Make sure you do this until the seeds reaches over 3 inches in its height and produces multiple mature leaves.
  • Proceed in transplanting the mimosas in permanent beds during autumn 6 weeks prior to the first frost. Pick a planting site with complete sun about 20 ft away from the other trees, structures, and utility lines.

  • Keep checking the soil for moisture daily by opening the bag. Remember that the soil should be moist and not soggy.
  • Gently pull the stem and test the cut for roots after 3 weeks. If it easily moves, then the roots haven’t formed yet.
  • You will notice that the roots have properly formed when you experience some resistance during the pull.
  • It is safe to remove the plastic bag once the roots have been formed. You can let it grow on a smaller pot for the next 2 months.
