Growth period characteristics of peony

The growth period of peony is related to the change of season. In spring, after the temperature rises, the buds will begin to germinate and appear leaf buds or flower buds. With the increase of temperature, the leaf buds begin to grow stems and leaves, the flower buds pull out the flower stems, the leaves on the flower stems will bloom, and the flower buds can differentiate again after the flowers fade.

Characteristics of flower bud differentiation of peony

Flower bud differentiation is very important, because it is related to the flowering of peony. In the growth process of peony, flower bud differentiation usually takes a long time. Generally speaking, the flower bud differentiation of single petal peony takes three months, which is generally completed from the late August to the early September. For the double petaled peony flower, the time of flower bud differentiation is longer, which usually takes three and a half months. The flower bud differentiation can be completed in late November.

Flowering characteristics of peony

Peony flowers also have different characteristics when they bloom. When the climate is normal, in February every year, the bulb buds of peony begin to grow, buds begin to appear when they wake up, and flower stems begin to be pulled out at the spring equinox. During the Qingming Festival, the flower buds increase and bloom before and after the Gu rain.

The whole process is very long, and the main factor affecting its flowering is temperature. The level of temperature can promote the peony to bloom early or late. In terms of this characteristic, ensuring sufficient accumulated temperature can promote the flowering of peony. If the accumulated temperature is insufficient, it can not bloom immediately. At this time, the temperature can be increased and the flowering of peony can be accelerated.

Growth characteristics of peony flower roots

The root growth of peony is also affected by temperature. When the temperature is lower than 4 ℃, the root of peony will be in a semi dormant state and its growth will stagnate. In the second year, after the temperature rises, it will start growing again and accelerate with the growth of temperature. In summer, when the temperature is higher than 30 ℃, it will also enter semi dormancy. After entering autumn, the temperature drops and the root of peony begins to grow again, but it will stop when the temperature drops to 4 ℃.
