The answer to 'how does hedge work' is that a hedge is a row of closely planted shrubs or trees that form a boundary or visual screen. Hedges are commonly used in landscaping to define property lines, create privacy, and add aesthetic appeal to a yard or garden. They work by growing together to create a dense, continuous barrier.
Hedges can be trimmed and maintained to the desired height and shape, and different types of plants can be used to create a variety of looks, from formal, geometric hedges to more natural, informal ones. Proper planting, watering, and regular pruning are important for keeping a hedge healthy and looking its best.
