Keep warm and cold to prevent frostbite.

For warm flowers, indoor operation should be done before the temperature drops. When the temperature is lower than 10℃, glass green, jasmine, azalea, begonia, hawksbill bamboo, Liriodendron chinense, Phalaenopsis, Gerbera jamesonii and Fusang should be moved indoors to keep warm. When the temperature reaches 5-6 degrees, lily, asparagus, chlorophytum, rubber tree and Clivia should be moved indoors and moved in the first frost.

Flowers planted on the ground should be wrapped with warm things to keep their stems warm, such as plum blossom, wintersweet, magnolia, elm leaf plum and oleander.

In addition, attention should be paid to ventilation indoors, which is good for people and flowers. Open the doors and windows at noon to ventilate, which is beneficial to the heat dissipation of potted flowers.

Flowers such as jasmine, cyclamen, crab claw orchid, rhododendron and clivia should be placed in a well-lit place to fully absorb sunlight, but long-term direct sunlight should be avoided to promote good photosynthesis and winter safety.

Water carefully when the temperature is low.

In winter, the weather is cold, and too much watering will cause the basin soil to freeze, cause frostbite to flowers and plants, and also affect the absorption of soil nutrients, so pay more attention to watering when the temperature is low.

Balcony, terrace, bay window flowers such as rubber tree, Liriodendron, Brazilian wood, Ficus, Fortune tree, jasmine, etc. should reduce the watering frequency and amount each time to keep the soil surface moist.

Chimonanthus praecox, Prunus mume and camellia with flowering in winter and early spring should be watered more, and the watering frequency and amount should be reduced to facilitate the formation of flower buds and promote their flowering.

Generally speaking, the best watering time in winter is from 10 in the morning to 1 1 or from 2 pm to 3 pm.

Indoor foliage plants such as green radish, bamboo and Anthurium andraeanum should be mainly atomized and sprayed with water. It is beneficial to water the basin soil and keep it dry. Remember to water it thoroughly.

Apply less chemical fertilizer, and apply chemical fertilizer lightly.

Clivia, calla lily, cymbidium, pineapple, etc. 0.2% potassium dihydrogen phosphate and 0. 1% urea can be made into mixed fertilizer solution for irrigation; Kumquat, pyracantha, etc. Can be irrigated with a small amount of low-concentration available phosphorus and potassium fertilizer; Milan, Zhu Lan, Jasmine, etc. , it can be topdressing with dilute phosphorus and potassium fertilizer 1-2 times.

For most foliage plants, it is necessary to stop applying nitrogen fertilizer and apply some low-concentration potassium fertilizer appropriately, which can increase the cold resistance of flowers.

It is also important to pay attention to pruning.

In order to be beautiful and absorb nutrients effectively, it is essential to prune potted plants moved indoors. Cutting off dead leaves, dense branches, diseased branches and twigs can fully provide nutrients for effective branches, so that potted plants can thrive and survive the winter safely. For the overgrown branches, the pruning can be strengthened, and for the potted plants that have been shaped for 1-2 years, the binding can be removed or unbound and then re-bound to prevent them from being in a fixed position for a long time.

Stump bonsai placed on the balcony, such as elm, magpie plum, triangle maple, banyan, Podocarpus, juniper and cypress, should be trimmed when necessary.

Jasmine, crape myrtle, pomegranate, etc. Pruning can be done in late autumn to reduce the consumption of nutrients in winter, promote the storage of nutrients in potted flowers and make them bloom more in the coming year.

Rooting is necessary to prevent and control pests and diseases.

The late autumn and early winter are the high season of pests and diseases, especially the temperature and humidity of potted plants are more suitable for the outbreak of pests and diseases, so the pests and diseases must be thoroughly carved out before moving the flowers into the house. During this period, flowers and trees are prone to diseases such as leaf spot and branch rot, and pests include scale insects, red spiders, aphids and whiteflies. Don't let them into the house to hurt potted plants and bonsai.
