The latest winter flowers should be protected from freezing.

Should pay attention to anti-freezing and heat preservation if there is a closed balcony, it is very beneficial for potted flowers to survive the winter; if there is no closed balcony, potted flowers should be admitted at night, and some potted flowers that are especially afraid of cold, such as tropical orchids, pineapples, poinsettias, andrographis andraeanum, have a room temperature of not less than 10 ℃ at night.

Attention should be paid not to excessive watering experts say that with small water evaporation in winter and stagnant growth of flowers and plants at low temperatures, too much water will make the roots dyspnea, which can easily lead to root disease or even rotting root death.

We should pay attention to basking in the sun to facilitate photosynthesis to produce organic nutrients and 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 larger and more beautiful.
