In a recent number of the Gardener's Monthly, in reply to Dr. C. A. K., Chester, Pennsylvania, in relation to planting evergreen hedges in close proximity to maple trees, planted twenty feet apart, you say you would not advise it under any circumstances, as the roots of the trees absorb the moisture the evergreens ought to receive.
About ten years ago I planted a Norway spruce and American arborvitae hedge within two feet of a row of maple trees that had been planted ten years before - the maples are now large trees. The hedges did finely - hardly lost a plant, and they were never watered except by rain. They are both very compact and in every way doing well.
Three years ago I planted thirty rods of hemlock hedge within four feet of a row of maples, and that hedge is growing finely.
A neighbor across the way, twelve years ago, planted an American arborvitae hedge under large cherry and maple trees - maple trees on both sides of hedge - in many places very much shading it. That hedge is now compact and beautiful, none of the plants died, and no water was used.
There is also an American arborvitae hedge in the neighborhood that was planted in a line with a row of maples five years ago, and it has done well so far.
