Even in the same area, the temperature is not the same. Spring is the most exuberant time for peony to bloom, and it is also the time when the temperature changes greatly. The temperature of warm spring and cold spring can differ greatly, so the flowering period will also differ by four to five days. When the temperature changes greatly, it is also possible that the flowering period differs by about 20 days.
Water is also a major factor affecting the flowering of Paeonia lactiflora. If the water content is insufficient, the flowering will be delayed. However, if the water content is too large, the flowering will be delayed.
If it rains properly before flowering, the flowers of peony will be very beautiful, large and colorful. But if the rainfall is too much, it will lead to shortened peony flowering, flower color is not gorgeous or even does not bloom.
The effect of altitude on the flowering of Paeonia lactiflora is mainly reflected by the difference of temperature and humidity. Different altitude, air temperature and humidity will be different, so the flowering period and flowers will be different or not.
Almost all plants can't grow without light, so can natural peony. The peony is fond of the sun. It grows in a sunny place. The flowers are brighter and more beautiful than those in the shade.
In spring planting, generally speaking, it won't bloom in that year, because the injured fleshy roots can't be recovered immediately; in autumn planting, the injured fleshy roots have enough time to heal, and generally bloom in the next spring.
