Q.watering weeping cherry tree in dry weather
How often should I water my first summer weeping cherry tree in dry weather? I set it out last fall. It is sitting in full hot setting sun and to the left some Bradford pears that may provide some shade.

you can buy a adapter for you garden hose that is a deep root waterer. You push the adapter into the ground beside the tree and turn the water on until you see it come up to the top.

You will want to water your tree deeply at least once a week during dry spells. Apply the water slowly, giving it a chance to sink into the soil as deeply as possible. Adding a 2- to 4-inch layer of organic mulch around the tree will also help the soil retain moisture.
