Trees also are a source of simple beauty and they utilize nutrients as they grow. If you look at the cost of buying and maintaining trees, they are a pretty good bargain when it comes to improving water quality in the Chesapeake Bay. When selecting trees for their property, a homeowner should consider intended function (privacy screening, shade, etc.), budget, size and the quantity of trees needed. This report also provides important information about how to plant, water, fertilize and mulch trees to ensure that they continue to thrive and contribute to the health of the Chesapeake Bay.
