Classification of overwintering requirements of foliage plants

First of all, according to the overwintering requirements of various indoor foliage plants, strengthen management, especially for the varieties with poor cold resistance, if necessary, focus on the places with temperature increase and insulation, so as to avoid the invasion of cold wind and avoid the adverse low-temperature period

Temperature treatment according to local conditions

Secondly, according to the change of temperature at the end of autumn, let it have a transitional adaptation process to low temperature, that is, when the temperature gradually decreases at the turn of autumn and winter, let the indoor foliage plants gradually exercise at a slightly lower temperature, which can significantly improve their cold adaptability, give full play to their cold resistance potential, and improve their resistance to low temperature. At the same time, in the low temperature period in winter, uneven temperature changes should be avoided, so as to facilitate the safe overwintering of plants. Because the sudden increase of temperature will make the plants that were originally in a relatively dormant state grow new shoots and leaves. At this time, if the temperature suddenly decreases, it is very easy to be frozen. Similarly, when early spring comes, the temperature changes indefinitely, and we should also pay attention to the cold and freezing prevention of indoor foliage plants, so we can carry out normal fertilizer and water management only when the temperature is relatively stable

Water and fertilizer management in winter

Third, do a good job in fertilizer and water management in cultivation, so as to facilitate cold and frost prevention. In the low temperature period in winter, the water content should be strictly controlled to make the excessive exercise in a relatively dry state. For most varieties, watering once for 5-7 days or more can maintain the normal life activities of the tree, which is conducive to the increase of cell fluid concentration in the plant and improve its cold resistance; Generally, no or less fertilization is applied in winter to control its growth and avoid cold and freezing; In addition, about a month before the low temperature in winter, in addition to the normal fertilization management, phosphorus and potassium fertilizer should be applied. For example, 0.3% - 0.5% potassium dihydrogen phosphate should be sprayed continuously every other week for 2-3 times to make the plant grow robust, so as to improve the cold resistance and overwintering ability of the plant
