Wet soil allows pathogens like pythium, verticillium, and fusarium to breed on it. These pathogens stay on the soil until the water is evaporated. Unfortunately, you can’t get rid of them by using fungicides. A healthy tree can recover from root rot in time with proper drainage.
The key for watering your Japanese Maples is to make sure you do not water too much. Japanese Maples do not like boggy or wet feet so it’s always important to make sure whether you’re in the ground or in a container that the tree has excellent drainage.
