Prepare loose and fertile soil, or make up with garden soil, rotten leaf soil and fine yellow sand.
Take out the prepared Mimosa seeds and soak them in warm water at about 30 ℃ for about 3 hours.
Prepare the flowerpot in advance, add the fertile soil, pave and compact the soil, and then pour it through the water. Plant the soaked seeds in the soil, and then water them. When planting, be careful not to bury them too deep, about 0.5cm. Then put the flowerpot in a warm place for maintenance. If the temperature is right, it will germinate in about 4 days.
