Red Spruce is only successful in the colder parts of zone 5. It does not tolerate heat or pollution well.
If you are in a cooler region of the county, red spruce provides food and cover for many mammals and birds. Red squirrels eat buds and seeds, rabbits browse twigs and foliage and porcupines feed upon the bark.
