The growth period of peony is related to the change of seasons. In the spring, after the temperature rises, the buds will start to sprout, and there will be leaf buds or flower buds. With the temperature rising, the leaf buds will start to grow stem and leaves, and the flower buds will draw out the flower stems. The flower stems will grow leaves and blossom, and the flower buds can be differentiated again after the flower withers.
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 petaled peony takes three months, generally from the late August to the early September. Double petaled peony flower, flower bud differentiation time to be longer, generally it takes three and a half months, to late November, flower bud differentiation can be completed
When peony flowers bloom, they also have different characteristics. When the climate is normal, in February of every year, the bulbils of peony begin to grow, buds begin to appear at the time of hibernation, and flower stems begin to be drawn at the vernal equinox. It is clear that the flower buds increase and bloom before and after the rain.
The whole process is very long, and the main influence on its flowering is the temperature. The temperature can make the Peony Blossom earlier or later. From this point of view, to ensure enough accumulated temperature, can promote the flowering of peony, insufficient accumulated temperature can not immediately bloom, at this time can increase the temperature, can accelerate the flowering of Peony
In fact, 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 the growth will be stagnant. When the temperature rises in the second year, it will start to grow again, and it will speed up with the growth of temperature. In summer, when the temperature is higher than 30 ℃, it will also enter semi dormancy. In autumn, when the temperature drops, the roots of peony will start to grow again, but when the temperature drops to 4 ℃, it will stop.
