Watering houseplants

Fill containers the night before so the water is at room temperature and, if you leave caps off, some chlorine will evaporate into the air.  To provide higher humidity, group plants or use pebble trays. While watering, look for any pests such as spider mites that may have infested plants that have dried out.  Washing houseplants in a sink or tub (except for hairy leafed varieties such as African violets) is a good first step in pest control.    Rotate plants a quarter turn every week to prevent them leaning to the light.
