How often should I water a newly planted Kousa Dogwood tree?

A newly planted Kousa Dogwood tree should be watered deeply about once a week, ensuring the soil remains consistently moist but never waterlogged. During periods of extreme heat or drought, additional watering may be necessary to prevent stress. Applying a layer of organic mulch around the base helps retain soil moisture and regulate temperature while reducing weed growth. Once the tree becomes well established, it is more drought tolerant but still benefits from occasional deep watering during extended dry spells.
