DEFINITION OF HEDGE
A row of shrubs or trees planted closely enough to form a fence or boundary. In most landscaping applications this shrub spacing works out to an average of 3 to 4 feet apart on center.
For some people, the first thought of a hedge reminds them of the neatly trimmed boxwood hedges forming a maze at historic Williamsburg, Virginia, or the privet hedge around their family’s yard during their youth.
Fact of the matter is, a hedge can be comprised of just about any type of tree or shrub, but certain varieties of plants do seem to dominate the selection list. Some woody plants make better candidates for shearing, and some varieties, like privet, tend to be much less expensive and common than say, boxwood.
Rule #1 – Shape the hedge so sunlight can reach the lower branches. Keep the sides wider at the bottom, or at the very least, keep the sides ‘straight up and down.’ Bottom line: Don’t let the top get wider than the base.
Rule #2 – If the hedge is a flowering variety, trim it within one month of when it finishes blooming. This allows time for the hedge to form new blossoms for the next flower show.
Rule #3 – Mulch the base of the hedge to ease mowing and prevent weed whackers from damaging the bark on the trunks.
Rule #4 – Remove weeds, vines and other plants that attempt to grow up inside the hedge. Maple trees and vines can be tough competitors!
Rule #5 – Be careful working from ladders. Consider keeping the hedge at a height you can trim while standing on the ground.
Rule #6 – If you have trouble cutting the hedge straight ‘by eye’ consider stretching a string line as a guide. Most home centers and hardware stores sell mason’s line that can be stretched taut. Place the line where it won’t get in the way or cut by your trimmers.
