Another part of arborvitae care is proper pruning.
While most arborvitae will keep their borders even and neat naturally, some will have branches jutting out that can be an eyesore.
Removing these will make the plant seem healthier.
Pruning an arborvitae down to a hedge shape will also allow the plant to grow healthier, and allow for the lower branches to have direct sunlight.
More information about arborvitae care can be found on the Internet.
Many websites exist that have helpful hints and tips for caring for arborvitae trees.
Local nurseries and garden centers will also be able to answer any questions about arborvitae care. Libraries have a variety of books that are about plants and some that are specially dedicated to arborvitae care.
