Under normal circumstances, it is not normal to have too much water in the cage of pitcher plant. Generally, one third of the water in the cage is the best. Usually, it's better not to water the cage. Its cage secretes mucus, which will drown the insects and decompose them for digestion. If there is no water in the cage, it's better not to add it by yourself. Of course, it doesn't mean that it can't be added, because if the water used is not clean, the cage of pitcher plant grass may rot.
1. Humidity: if you want its cage to grow normally, you need to ensure the humidity of the breeding environment. The maintenance environment should not be too dry. You should spray more water and keep the humidity above 75% as much as possible.
2. Temperature: the temperature of breeding should not be too low, especially in winter, if the temperature is too low, it will affect the growth of cage. The lowest temperature should not be lower than 15 ℃, during the winter must put it indoors.
