<human>:  What are the best methods for watering plants?
<bot>: The best methods for watering plants depend on the type of plant and its growing environment. For outdoor plants, the general rule of thumb is to water deeply, about once per week. In hotter climates, plants may require more frequent watering. Container plants may need daily watering. Deep watering encourages a healthy root system, so this is the preferred method. In addition, it's best to water early in the day so that the water has a chance to absorb into the soil and the plants have less chance of developing fungal diseases due to wet foliage in the evening.
