1. Provide sufficient light: Poison killer is a kind of plant that likes sunshine.In winter, it is recommended to put it in a place where the sun can shine directly.This will allow it to receive more light, which is conducive to its winter.
2. Prevent the plant from freezing: In winter, the drug grass should be raised in a place where the temperature is above 0 .If the plant is planted in the field, it should be covered with film to keep warm, so as not to freeze it.
3. Temporarily stop pruning: Because the poisonous weeds usually grow faster, they are usually pruned regularly to keep them in good plant type and growth state.But it grows slowly in winter, so you can stop pruning temporarily and cut it off only when there are bad branches and leaves on it.
4. Reduce the frequency of watering: In winter, the frequency of watering the poisonous weeds should be reduced appropriately.Because of the low temperature in winter, it grows slowly and does not need much water.Overwatering is likely to cause waterlogging and growth problems.
Toxic weeds have a certain degree of cold tolerance, but can not tolerate extreme low temperatures.If it is placed in a place where the temperature is below 0 C in winter, it may be frostbitten and grow poorly.If it is kept in a cold place for a long time without taking measures to keep it warm, it may be frozen to death.
