1、 Potted planting

The winter in the north is relatively cold. If it is potted for maintenance, it should be moved indoors for the winter. At the end of autumn, the bulbs should be cut off and dried in a ventilated and cool place. Then they should be placed in a sand basin without watering or exposure, as long as they remain dry

In addition, another way is to put it in the flower pot to let the bulb sleep naturally. Pay attention not to water. The indoor temperature should be below 23 degrees. If the temperature and water are not controlled, the plant will continue to consume nutrients, which will affect the flowering and growth of next year

2、 Field planting

If a large area is planted in the open, it cannot be placed indoors for the winter. When winter comes, the leaves on the ground begin to dry and collapse. At this time, cut off the withered branches and leaves and cover the plants with film, straw mat or soil, so as to keep warm and moisturize. At this time, pay attention not to water, otherwise the underground seed ball is easy to be frostbitten and damaged. Or you can dig out the seed ball and store it in sand, which can also keep warm. After winter, seed the ball in time
