How often do you have to water the Japanese maple?

Since the Japanese maple is one of the shallow-rooters and also always prefers a slight moisture, regular watering is essential, especially in the hot and dry summer months. Make sure, however, that no waterlogging forms, because the tree is extremely sensitive to this. It is best to water in the early morning or evening hours, whereby the leaves should not be wetted.
