Incorrect watering is probably the greatest cause of failure in growing interior plants. The most common question plant growers ask is, "How often should I water my plants?" There is no easy answer to this question. Some plants prefer dryer conditions than others. Temperature and humidity also affect how often one needs to water plants. Temperature and humidity will vary from day to day, week to week, and season to season. A good watering schedule in the spring may be totally inadequate for the summer, fall or winter. The best answer to this ques tion, though somewhat vague, is, "Water your plants when they need it!" Most people water their plants either by a calendar schedule or when the surface of the soil becomes dry. Both systems usually result in overwatering. To adequately water a plant, you must know when to water and how much water to apply.
