The latest management methods of potted peony in winter

Peonies can not only be planted on the ground, but also can be cultivated in pots for viewing. And peony has strong cold tolerance, so we don't have to take special care of it in the south, which is relatively warm in winter. But the winter in the north is really very cold, so we can't manage it as we do in the south.

Before and after the Beginning of Winter, the northern area was already relatively cold. So we should move the potted peony to the bright place indoors in time to keep the room temperature above 0 °C. But next spring should not be too early to move outdoors, because the temperature in the early spring in the north is still very low, potted peonies still can not stand the outdoor cold spell. It is generally necessary to wait until the temperature before and after the Qingming Festival is relatively warm and stable before moving it outdoors.

For areas with relatively high temperatures, we do not have to move them indoors to keep warm in winter, we can avoid the tuyere and choose a place where the air flow is relatively stable, bury the flowerpot underground and keep the basin surface at the same height as the ground. This can not only maintain the humidity of the potted soil, but also maintain the temperature of the potted soil, which provides a guarantee for the safe and smooth wintering of potted peony. When the peony begins to bud in the spring of the following year, we will dig the flowerpot out of the ground and carry out maintenance and management in accordance with the normal procedures.

Keeping warm from the cold is a key link in the winter management of potted peonies, but in order to ensure a good flowering effect in the coming year, some other aspects of winter management can not be ignored.

1. Pruning

After entering the winter, the peony immediately enters the dormant period, and the plant is basically in a state of stagnant growth, so it is very suitable for pruning at this time. The winter pruning of potted peony should be carried out on the basis of keeping the plant type round, mainly cutting off the sprouting tiller branches at the base of the plant and the overlapping branches, cross branches, thin branches of diseases and insect pests, etc., in order to retain the sturdy branches with flower buds. In order to achieve better ventilation and light transmission effect, the pruning of potted peony should be coordinated and appropriate.

2. Removal of leaves

After entering the winter, the leaves of the peony will gradually dry up, and the harmful substances such as bacteria and eggs attached to the leaves will continue to be retained. Therefore, we should cut off these dry branches and leaves in time, so as not to fall into the basin soil and continue to spread and harm the plants in the coming year. But in the process of removing leaves, you should be careful not to hurt the flower buds, and at the same time pick up the dead leaves that fall off on the basin, and then burn them centrally to kill the diseases and insects as much as possible.

Third, watering

Because the peony is basically dormant in winter, the consumption of water is very small. Although it sometimes seems that the soil on the surface of the basin soil has become dry, we do not need to replenish it. And in case of rain and snow, we should move the potted peonies to a place where rain and snow can be sheltered in time, so as not to cause the phenomenon of rotten roots caused by the fault of the basin soil.

IV. Fertilization

Peony is a kind of fertilizer-loving flower plant, even in winter, we should properly replenish it with nutrients to ensure a good flowering effect in the coming year. However, in order to ensure the safety of fertilization in winter, it is recommended to apply organic fertilizer, topdressing with semi-rotten cake fertilizer or human and animal urine. Of course, you can also apply a small amount of compound fertilizer, but you need to dig holes with a depth of more than 10 centimeters.

5. Weeding

Although it has entered the winter, but the vitality of some weeds is very tenacious, even in the cold climate, often can survive. This is bound to continue to absorb the nutrients in the basin soil and strengthen the nutrients needed by the peony in the past. Therefore, we should remove the weeds in the flowerpot in time to avoid competing for the nutrients of the peony. However, it is recommended to use the method of turning deep into the basin soil, on the one hand, it can get rid of weeds, on the other hand, it can also play the role of loosening the soil, and help to survive the winter smoothly.
