Why would someone need to water indoor plants more in the winter than in summer?
During the winter, the relative humidity inside a home can drop to an extremely low value and the inhabitants are usually unaware of it. When cold polar air is brought indoors and heated, its relative humidity decreases dramatically. For example, when outside air with a temperature and dew point of 5°F is brought indoors and heated to 68°F, the relative humidity of the heated air drops to 8 percent-a value lower than what you would normally experience in a desert during the hottest time of the day.

Very low humidities in a house can have an adverse effect on living things inside. A house plant, for example, would have a difficult time surviving because the moisture from their leaves and the soil evaporates rapidly. Thus, they usually need watering more frequently in winter than in summer.
