After being subjected to light frost, the lily of the valley will have large, cone-shaped flower buds with rhizomes, and then be treated with low temperature. The processing time depends on the temperature. For example, it takes 30 to 40 days at 0 ℃.
It is better to use pot culture, and choose fertile and loose culture soil as culture medium. The best planting depth is 1-2cm of sprout soil. Cover with moss to keep moisture.
After planting, water the lily, and put it in the dark environment with a temperature of about 20 ℃ for 8-12 days. When the bud sprouts, raise the temperature to about 27 ℃. When it is found that the buds are about 5cm long, the covered bryophytes can be removed and moved to the sunny place. At the same time, pay attention to the management of fertilizer and water. When many flower buds are full and about to bloom, the temperature should be reduced to about 13 ℃, at the same time, pay attention to ventilation and reduce watering properly.
