Seeds germinate faster when the soil temperature is about 15 degrees, and slow when the temperature is more than 25-30 degrees. Therefore, seeds can be sown from early spring to midsummer. The following are the specific operation steps for planting dandelion seeds:

1. Seed collection

To plant dandelion, we first need to get dandelion seeds.

The shell of dandelion disk changes from green to yellow green, and the seeds can be harvested when they change from milky white to brown. Do not harvest them when the disk cracks, otherwise the seeds are easy to fly away and lose.

It is said that a long time ago, a 16-year-old girl suffered from breast carbuncle. Her breast was red and swollen, and the pain was unbearable. But she was ashamed to speak and had to bear it. Her mother knew about it. In feudal society, I never heard that a big girl would suffer from breast carbuncle. I thought my daughter had done something shady. When the girl saw that her mother doubted her chastity, was ashamed and angry, and had no face to see others, she secretly escaped from her home at night and committed suicide in a river. It happened that there was a fishing boat by the river. A husband surnamed Pu and his daughter Xiaoying were fishing in the moonlight. They rescued the girl and asked why they threw themselves into the river. The next day, according to her father's instructions, Xiaoying dug a kind of grass from the mountain, washed it, mashed it into mud, applied it to the girl's breast carbuncle, and soon recovered. Later, the girl brought the grass back to her home for planting. In memory of the fisherman's father and daughter, this wild grass is called dandelion.
