Seeds can be sown in spring and autumn. Before sowing, the seeds can be soaked in warm water at 35℃ for 24 hours, and then sown in shallow pots, covered with 65,438+0-2 cm soil. At the temperature of 65,438+05-20℃, the seedlings were soaked in pots for water supply, kept moist, and emerged in 7-65,438+00 days, with the height of 5 cm. When picking seeds, choose strong mother plants, strengthen management, pick with maturity in the fruiting period, and the pods will automatically crack when mature.
⑵ Cultivation
There are no special requirements for maintenance and management. Generally, soil can be cultivated, and fertilization is not needed during the growing period. It is enough to apply dilute liquid fertilizer for 2-3 times, and it is not advisable to use too much fertilizer. It is enough to grow strong and have green leaves, not long, because mimosa is mainly an interesting foliage flower, and the small one is better.
The planting technology of mimosa is simple and the management is extensive. The requirements for climate, sunshine and soil are not strict, but the fertile and loose sandy loam is better, and the warm and humid environment is better.
1, planting method. Generally sow and propagate, and sow from late March to early April. Spread the seeds evenly on the fine soil, covering about 65,438+0.5 cm. When the temperature is about 65,438+08℃, the seedlings can emerge in about 65,438+00 days (usually they will grow after being buried without special management). Seedling growth is slow, and it can be planted when it is 7-8 cm.
2. On-site management. Plant spacing is 25-30cm, loosen soil, weed and water in time. Potted indoors, watered every day in summer 1 time. Fertilize every month 1 time. If you don't want the plant shape to be too big, you should reduce the amount of fertilization or even don't need fertilization.
3, pest control: basically no pests and diseases. If there are slugs, they can be controlled with fresh lime powder in the morning.
No, sunshine is sunshine.
Light is light.
