How should Canna survive the winter? In fact, different regions have different ways of wintering. Basically, in the south of the Yangtze River, because the light and temperature are relatively suitable, winter can be spent in the open air, but in the north of the Yangtze River, the temperature and light are relatively poor. Pay attention to the cultivation of Canna, we need to pay attention to, take certain winter measures.
The specific way to survive the winter is to cut the old plants of Canna from the lower part of the stem before the frost falls, and then put some plant ash on the wound to dry it. By the time of 3 days or so, the wound is dry and can be covered with a layer of straw to keep warm and protect it from frostbite. In addition, it can also play a certain role in moisturizing. In addition to straw, can also be directly buried with soil, but to ensure that the plant ventilation.
After thawing the soil in the spring of the second year, the mulch can be removed, but a layer should be kept to prevent cold in the late spring. In March and April, people can sprout.
In the northern region, if the winter is very cold, it is possible to store Canna covered with ice, so we can dig out the underground roots and store them in winter.
After the part of Canna on the ground is withered, cut it out, dig out the root, and dry it, then it can be buried in the indoor ventilation place, buried in the sand, keep the temperature above 5 ℃, do not water, you can have a safe winter.
Or choose the outdoor leeward and sunny place, dig a pit to bury it, the depth is generally about 1m - 1, 5m, fill some straw and soil, you can safely winter.
After the spring temperature rises in the next year, it can be taken out for planting.
