We have several in our garden the sweep the ground.
The Blue Spruce is the smallest one but it hugs the ground. Birds love to nest in it. Where it touches the ground it gives a warm place for rabbits and any other creature to snuggle up and sleep in away from the wind. I hate to see Pines trimmed half way up the trunk. These are so sad trees.
Pine trees should sweep the ground......here is a Bobcat who has been sheltering under the pines
Think of the Rabbits and other small creatures out looking for food. They need places to hide. These are happy pine trees, doing their job.
