Premium double ground mulch may be installed at any time of the year, but most commonly in the spring or immediately after installation of new plants. Some Clients may wish to re mulch in the Fall, to give the beds a fresh look to last through the Fall and Winter months. Some clients choose gravel in lieu of hardwood mulch. Gravel is available in a variety of colors and types, and provides for a longer lasting, elegant appearance.
