First, pay attention to frost protection. If there is a closed balcony, it is very beneficial for the potted plants to pass through the winter; if there is no enclosed balcony, the potted plants should be put in the room at night, and some particularly cold potted plants, such as tropical orchids, pineapples, poinsettia, and red palms, etc., the room temperature at night should not be low. At 10°C.
Second, be careful not to over-water. Experts said that the small amount of water evaporation in winter, coupled with the stagnant growth of flower plants at low temperatures, excessive moisture will make the roots poorly breathable, easily lead to root disease, and even rot to death.
Third, pay more attention to the sun, in order to use photosynthesis to generate organic nutrients, so that the cold resistance of plants; for some winter flowering flowers, but also conducive to lush foliage, flowers bloom bigger and more beautiful.
Fourth, we must pay attention to not apply more nitrogen fertilizer. Absorption capacity of winter flowers is not strong. Applying too much nitrogen fertilizer will harm the root system.
Fifth, we must pay attention to disease prevention and pest control, mainly against scale insects and aphids.
Experts reminded that due to the relatively dry weather in winter, we must also pay attention to the spraying of foliage to change the situation of excessive dryness and heat in the interior.
