Potted flowers should master solar terms when overwintering.

In the north, potted flowers have been maintained indoors for nearly half a year, so they should be maintained scientifically according to the different habits of potted flowers and the changes of solar terms.

1. Frosts Descent enters the house with potted flowers during the holiday season. After Frosts Descent, the temperature dropped significantly, and some cold-averse flowers originating in the tropics or subtropics, such as Milan, jasmine, Fusang, poinsettia, variable-leaf wood, dragon spitting beads, and pulpy plants such as lotus, measuring ruler, epiphyllum, and so on, need to be moved indoors for maintenance in time to avoid low temperature. The well-lit and warm south windowsill is conducive to the winter and robust growth of potted flowers. At this time, indoor potted flowers should pay attention to watering and ventilation, lest the room temperature is too high, resulting in leaf yellow shedding.

2. The Beginning of Winter and Lesser Snow, step up efforts to refine seedlings. Before and after Lesser Snow, Fusang, Milan, geranium, rhododendron, Magnolia and so on should control watering and stop fertilizing to make them dormant or semi-dormant. Such as rubber trees can be watered once a month, Magnolia, Milan pot soil dried and then watered, so that arrow lotus, tiger tail orchid and crab claw orchid and so on to keep dry. Otherwise, the plant metabolism is exuberant, the stems and leaves grow only, the tissue is soft, and is vulnerable to cold injury.

3. Beware of frost injury in two cold seasons. Big Lesser Cold is the coldest season of the year. At this time, it is a critical time for potted flowers to spend the winter. Milan, Fusang, variable leaf wood and all kinds of cactus grafted with day ruler should be covered with plastic bags or temporarily build a double-layer plastic shed to protect against cold, and cover the canopy with a thin cotton pad at night to prevent heat dissipation at night; if possible, electric lights or temporary stoves are used to increase room temperature. Magnolia and jasmine can also remove some leaves to enhance cold resistance. Maintenance, choose sunny days, no wind at noon watering, it is best to spray with water close to room temperature, but should not be too wet. In rainy and snowy days, it is more ideal for geraniums, African violets and glass begonias that bloom in winter to increase auxiliary light, and pay attention to the opening of doors and windows and clogging of cracks, so as to prevent a large number of fallen leaves, such as deciduous wood, mulberry, jasmine, etc. or even wither and freeze to death.

4. Protect against cold and seedlings before and after the Beginning of Spring. After the Beginning of Spring, the temperature began to rise, and the potted flowers also began to sprout and grow, but the root system has not yet fully returned to normal function, and a little carelessness will cause the water in the plant to lose balance and suffer from the cold in spring. Winter potted flowers, at this time should pay special attention to the adjustment of temperature and humidity to ensure safety.

5. Ching Ming Festival came out of the room safely. At this time, the temperature has risen steadily, and can be released one after another according to the cold resistance of potted flowers. Pay attention to ventilation after moving outdoors and gradually adapt to the outdoor environment. The more hardy camellia, orchids and rhododendrons can come out earlier, while Fusang, jasmine and Milan should be late rather than early. In order to prevent the damage of night frost, cover the potted flowers with Reed curtain or film at night to ensure the safety of potted flowers.
