Hedge trimming involves cutting and shaping rows of closely planted shrubs or trees. Using tools like hedge trimmers and shears, you prune the hedge to maintain its desired size and form. Timing matters: formal hedges need multiple trims per year, while informal ones can be pruned annually. Trim the top first, angling cuts for sunlight exposure. Avoid flat tops and aim for a slightly narrower top than the base. Regular trimming services ensures a healthy, well-shaped hedge.
