Stacked stone adds a beautiful, finished look to a new or existing flower bed. Adding stone around existing trees, helps define the tree ring not only for beauty but also to help hold mulch around the area. We set our stacked stone either dry on a crushed granite base or with mortar mix for a permanent addition. For those with smaller budgets, just adding a little rock either with one layer or smaller pieces can add curb appeal to an existing landscape. There are many options for which type of rock to use depending on the desired look and budget.
