For the first 3 years after planting, all trees need regular water to get established. Don't rely on lawn sprinklers - they do not soak soil deeply enough to encourage a healthy, deep root system for your tree.
The roots of a young tree are located mostly near the trunk.
The easiest way to water young trees? Drill a small 1/8" hole near the bottom of a 5-gallon bucket. Place it near the rootball, fill it with water, and allow it to slowly drain into the soil.

You can also use a small soaker hose, drip tubing or emitters, or a hose sprinkler on a very low setting. Avoid spraying the trunk, and expand the watering zone outward as the tree grows.
