How to maintain flowers without frostbite caused by sudden changes in temperature?
How to protect flowers from frostbite caused by sudden changes in temperature.
It is understood that there will be a new big cooling, so how can we not be frozen by this sudden cooling of the flowers, here are some suggestions:
First, we should pay attention to anti-freezing and heat preservation. If there is a blocked balcony, it is very beneficial for potted flowers to survive the winter; if there is no blocked balcony, potted flowers should enter the room in the evening, and some potted flowers that are particularly afraid of cold, such as tropical orchids, pineapples, poinsettias, andrographis andraeanum, have a room temperature of not less than 10 ℃ at night.
Second, we should pay attention to not watering too much. Experts say that with small water evaporation in winter and obstacles to the development of flowers and plants at low temperatures, too much water will make the roots breathe poorly, which can easily lead to root disease and even root decay.
Third, we should pay attention to not applying more nitrogen fertilizer. The receptive capacity of flowers in winter is not strong, too much nitrogen fertilizer will endanger the root system.
Fourth, we should pay attention to basking in the sun to facilitate photosynthesis to produce organic nutrients, so as to improve the cold resistance of plants; for some flowers that bloom in winter, they are also conducive to luxuriant branches and leaves, and flowers bloom bigger and more beautiful.
Fifth, we should pay attention to disease prevention and pest control, spray targeted drugs + new high-fat membrane to thoroughly prevent disease and control pests.
Experts remind that because of the dry weather in winter, we should also pay attention to foliar spray to change the situation that the room is too dry and hot.
These tips hope that we can come in handy in the face of cooling and conserving flowers.
