1、 Control temperature

When breeding in winter, the temperature should not be lower than 5 ℃, otherwise the plant is easy to be frostbitten. If the temperature continues to be low, the leaves are prone to yellowing, and wither and die in serious cases. It should be moved indoors before frost falls. It can grow normally indoors in the north

2、 Replenish sunshine

The sunlight intensity in winter is low and will not stimulate the plant, so you can choose to contact the sunlight at this time to promote the synthesis of nutrients and keep the branches and leaves green

3、 Regular water change

For hydroponic plants, although they grow slowly in winter and have less bacterial proliferation, they should pay attention to changing the water regularly, otherwise the plants often soak in unclean water, the growth will be affected and may rot

4、 Pay attention to ventilation

Ventilation should also be paid attention to. It is optional to properly contact fresh air when the temperature is high at noon, which can reduce the possibility of diseases and pests, but do not blow cold wind

5、 Precautions

If the indoor temperature is very low during breeding, the plants previously hydroponically cultured can be changed into soil culture, which can reduce the possibility of frostbite. When the temperature rises next spring, wash them and turn them into hydroponics
