In June, dig out the bulbs in dormancy period, or directly buy seed balls, dry them and store them in a cool and ventilated place, keep them dry, and plant them in October.
Choose sand or sandy loam with good drainage performance, which is rich in humus, and can be exposed to the sun before use. Loosen the loam before planting.
In order to sterilize the seed ball in the solution of 1000 times of tobuzin and 1000 times of acaricide, the whole seed ball needs to be completely immersed in it. The time should be controlled at about 20 minutes, not more than half a day. After disinfection, it should be dried in a cool place and planted on the same day.
The top of the seed ball is 4-5cm away from the soil surface. Keep the temperature below 12 ℃. After planting, if you feel the potted soil is dry, you can properly water it to facilitate the root growth. Almost half a month can develop very well, the root system can be moved to the greenhouse after complete development.
