1. For dandelion, the most suitable growth temperature is between 20 and 25 degrees. At this temperature, its growth rate is relatively fast, but it can also withstand the low temperature of MINUS 30 degrees, but its growth will be slower.

2. Dandelion has strong adaptability, so it is drought-resistant and heat-resistant. It can germinate at the temperature of 15-25 degrees. When the temperature exceeds 30 degrees, it will germinate slowly. For leaves, the most suitable temperature for growth is about 20 degrees.

3. Wild dandelion usually blooms in May-June every year. The longer it is, the more flowers it will bloom. Generally speaking, there will be more than 20 flowers at most, and the seed maturity is relatively short, about 13- 15, and the disk shell will turn yellow.

4. Dandelion is usually planted in March-April in spring or September-65438+1October in autumn. The temperature in these two periods is suitable for growth, so it is necessary to collect seeds in advance, then do germination treatment, and plant them in suitable soil in spring, so the growth rate will be faster.
