Tree Spacing For Colo. Spruce I am going to be planting some 4' Colorado Blue Spruce trees. I live in Central Nebraska, and water will not be an issue. But i do have another question about watering. I was wondering if it is alright for your lawn underground sprinklers to water your trees, instead of a drip system. If it is ok for the water to hit the needles. Thanks!
