Watering Trees for winter
With all the rain in southern Mn this fall, do you still recommend watering trees, 3 years old for this winter season?

Need to water will, of course, depend on the amount of rain we receive this fall. The amount of water required by a tree depends on its size, your soil type (clay, sand, etc.) and the kind of tree. Here is a publication that will help you determine how much water your trees need. Then track the amount of rainfall you receive. If it is not enough, then water your trees accordingly. If you receive sufficient rain, then you do not need to supply additional water.
For future reference, here is also a good publication on watering newly planted trees and shrubs: http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/watering-new-trees-shrubs/index.html
Note that evergreens and conifers are especially sensitive to winter desiccation by winds and cold, so watering is important up until soil freezes. http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/protecting-from-winter-damage/
