During the dormancy period of flowers, it is necessary to avoid excessive room temperature, otherwise it will affect the normal dormancy of plants, lead to excessive nutrient consumption, affect the growth and flowering of the next year, and even lead to death. Common flowers such as white orchids, azaleas, osmanthus, oranges, etc. Can you overwinter at room temperature above 5℃ and 8℃? 12 is the best; Smile, Milan, Riley, Fusang, etc. Room temperature should be10-15; Winter jasmine, oleander, rose, fig, pomegranate, pine and cypress are not suitable for high temperature, and can safely overwinter at room temperature not lower than 0.

Control water and fertilizer

Flowers entering dormancy should strictly control the supply of water and fertilizer. Too much watering can easily lead to root rot and yellow leaves falling off. So in addition to the varieties that grow and bloom in winter and spring, such as chrysanthemum, cyclamen, calla lily and so on. Water supply can be continued as needed, and all dormant flowers should be watered in a controlled way, such as smiling and Riley.

Its pot soil is slightly drier than that in summer and autumn, and there are some other flowers such as cactus. In addition, dormant flowers should pay attention to less fertilization or no fertilization, so as to avoid promoting new shoots in advance, affecting flowering in the coming year or suffering from freezing injury.

Plastic trimming

When some dormant flowers are about to sprout in early spring, they can be combined with plastic surgery to cut off the branches that are too strong, too thin, with pests and diseases and too dense, so as to facilitate ventilation and light transmission, concentrate nutrition and breed more and fuller flower buds. There are also some varieties, such as Riley, which can leave 20-25cm branches and cut off the rest; Too old branches can be cut off from the base to stimulate them to produce strong new branches. Rhododendron and camellia generally do not need pruning, just cut off some branches that are too dense and too long. Four. Pollution prevention: potted flowers are placed indoors for too long, and a lot of smoke and dust often accumulate on the leaves, which is easy to pollute the leaves. At first, dark brown mildew spots will appear on the surfaces of flowers and leaves. After a long time, it will form a black soot fog layer, which will affect the photosynthesis of plants, slow down the growth of flowers and cause diseases. Therefore, when planting flowers indoors, especially in a room heated by coal fire, attention should be paid to preventing smoke pollution, and the floating dust on the leaves should be washed clean with water close to room temperature.
