Watering House Plants Of all the things done to house plants, watering is probably the one cultural practice that causes the most problems. Watering is affected by the type of soil used, light exposure, temperature, and humidity.
Many factors determine when a plant needs to be watered.
Just as many environmental factors change with the seasons, so do the water needs of plants. The two main aspects of watering to be considered are frequency of watering and amount of water applied. The watering frequency is simply how much time passes between waterings. The frequency will vary over the course of the year. Avoid watering on a fixed schedule such as every week or every 5 days.
