Bonsai Watering

In the summer, during hot weather when the temperature is over 90 F degrees, water the bonsai plants one or more times a day. If the plants are in an unusually sandy soil they will require watering three or more times a day.

In early autumn, follow the watering directions for late spring. In late autumn, follow the watering directions for early spring.

In winter, keep the trees in a coldframe and ventilate the plants on one or more sides to keep them dormant. Check for dryness every 2 weeks. Water the plants every second day, or less, as required. Keep in mind that far more bonsai are killed by overwatering than by a lack of water.
