When is the general time for dividing peony plants?
The core content of this article: When is the general time for dividing peony plants and the explanation of green plant and flower care skills, such as understanding the propagation techniques of peonies. Let's learn about it together next.
Peony propagation usually adopts the method of dividing plants, which has the advantages of being simple and easy to operate; secondly, it blooms early, as the divided seedlings can bloom the following year; thirdly, it can maintain the good traits of the original variety. Let's learn about how to divide and plant peonies below.
Timely division and planting of peonies is beneficial for the healing of root wounds and can sprout new roots, enhancing their cold and drought resistance, which is advantageous for the growth of the following year. Therefore, it is not advisable to divide too early to avoid autumn emergence, which can affect the growth and development of the following year; it is also not suitable to divide too late, as the soil temperature may not meet the needs of peony root growth, resulting in poor growth of the new plants the following year. If delayed until spring for division and planting, the buds will sprout out of the soil. Due to the gradually increasing temperature and lower humidity in spring, the transpiration rate is high, and the injured roots after division cannot absorb water and nutrients normally, causing the weak growth of the cut plants, or even death. In the northern regions, division can start at the end of August and continue until the end of September, while in the southern regions, it can be carried out from the end of September to the beginning of November.
When dividing, carefully dig up the fleshy roots to minimize root damage. After digging, remove the old soil, cut off the old and rotten roots, and split them apart with a knife in the gaps. Generally, each plant can be divided into 3 to 5 daughter plants, each with 3 to 5 or 2 to 3 buds. The thick roots should be preserved during division. If the soil is moist, the peony roots are fragile and easy to break, so they can be dried in the shade for a day before dividing. After division, slightly dry them in the shade and dip them in nutrient-rich mud before planting.
The planting depth should be about 2 centimeters with the buds in the soil. Planting too deep is not conducive to germination and can easily cause root rot, leading to yellow leaves and不利于 normal growth. Planting too shallow is not conducive to flowering and is easily affected by frost, with the rootstock exposed to the ground. Under the intense sun in summer, it can lead to death. If the divided root cluster is large, there may be flowers the following year, but they will be small. Some poor root clusters can be removed to promote robust growth of the plant.
