How to Overwinter Chrysanthemums Indoors
Are you curious about the common knowledge of flower cultivation and the relevant experience with chrysanthemums, such as how to overwinter chrysanthemums indoors? If there are any mistakes, please feel free to correct them!
Chrysanthemum is a perennial herbaceous plant. How to manage it after the flowers wither in autumn and winter to make it bloom better the following year?
Due to the vast territory of our country and the large temperature differences in the north during winter, it is necessary to take different measures based on specific conditions to ensure the safe overwintering of chrysanthemums. In the warmer southern regions, for chrysanthemums grown outdoors, after the flowers fade and the plants wilt, cut the stems of the chrysanthemum 15 centimeters above the ground, water them once for overwintering, then cover them with leaves and dry soil, leaving 3-5 centimeters of the stems exposed to ensure safe overwintering. However, in the northern regions and north of the Yangtze River, chrysanthemums must be moved indoors to overwinter.
Below are two methods for overwintering chrysanthemums indoors.
(1) Root Preservation Method: After the flowers of the potted chrysanthemum fade, cut off the withered old stems, water thoroughly once, and then move it to a sunny room where the room temperature can reach 0-3 degrees. It is important to strictly control watering, only water when the soil is dry, and less water should be used, keeping the soil slightly moist, and also prevent the soil from freezing. As the weather gradually warms up in the second year, gradually increase the amount of watering and then move it to a sunny outdoor area for careful maintenance. After the plants sprout new buds, propagation methods such as division and cutting can be used.
(2) Bud Storage Method: In late autumn and early winter, select the first-generation of new buds sprouting from the roots of the chrysanthemum plant for cutting. During the operation, insert a knife 2 centimeters deep into the soil to cut the root stem with the new bud, dig it out with soil, and plant it in a prepared pot. The potting soil should be a mixture of half compost and half sand, then move the pot to a room with a temperature of about 3 degrees, water less, and keep the soil slightly moist. It is important to note that the room temperature should not be too high, nor should the plant be frozen to death. By mid-March of the following year, move it to a sheltered and sunny place outdoors.
