Having a formal or informal hedge can play an important role in the structure or character of a garden. They can act as a living barrier and add different colors, textures, or shapes than a typical fence. Hedges or screens also make excellent windbreaks or noise barriers (all depending on the type of plants you choose).
Hedges/Screens can be planted any way you wish, but there are two common practices for the plant placement. First, and the most common, is a single row. The single row works very well for formal hedges or areas where you want a nice screen without taking up too much yard space. Double row plantings are ideal for denser or wider hedges. For a dense double row hedge, we recommend staggering the plants so there are no empty spaces between the rows. These wider hedges are ideal for windbreaks. For a natural look use a variety of plants with different colors, textures, and flowering times.
Formal hedges need regular clipping to maintain their shape. For most plants you can trim them twice a year, continue reading for more information on pruning times on specific plants. Formal hedges can be pruned with shears or an electric trimmer. It is always a good idea to trim your hedge to be slightly wider at the base than the top. This helps to deflect strong winds and allows sunlight to reach the bottom of the plant. If you are considered about heavy snow sitting on the top of your formal hedges, trim the tops to point. Informal hedges require less maintenance, but still need reqular shaping. For the most natural look use hand pruners.
