Trees need water even before the leaves come out and during the growing season.
Newly planted trees need water in the Spring before the leaves are fully out. You can start watering your tree as soon as the ground thaws. Trees are healthiest when they receive an inch of rain a week during the growing season. During summer months this does not always happen. Trees also need a moist root system to get through winter in good shape. When Fall rains don't come, it helps to give them a drink so they will be healthy the coming Spring. Trees can be watered until the ground is frozen.

All trees need water, especially street trees!
In 2013, Minneapolis Park and Recreation Board put out the call to help water city trees.
"Trees up to five years old are especially susceptible. In any week that it rains less than one inch, yard and boulevard trees need to be watered. The Park Board plants and mulches boulevard trees but relies on residents or businesses nearby to water them." -Minneapolis Park and Recreation Board, July 17, 2013
We heard it and Brewing a Better Forest (TM) is our answer to engaging Minneapolis residents and business to water nearby street trees.
"Young, newly planted trees need additional watering care. For new trees, concentrate water over the root ball, as well as the planting area, to assure survival. This is most easily accomplished by creating a circular mound of earth (or mulch) 3 to 4 inches high around the plant at the edge of the planting area." - Dr. Weicherding, University of Minnesota Extension Educator
