Hedge

A hedge is a row of closely planted shrubs or small trees that forms a living boundary, providing privacy, wind protection, noise reduction, and habitat for birds and insects. In Finland, popular hedge species include privet (ligustrum), cotoneaster, hawthorn, alpine currant, and various spiraea cultivars. Evergreen options such as thuja and yew provide year-round screening.

A well-maintained hedge enhances property value and curb appeal while serving practical functions. Dense hedges can reduce wind speed by up to 50 percent on the leeward side, provide effective privacy screening, and absorb traffic noise. Flowering hedge species such as hawthorn and spiraea also contribute to the garden's ecological value by providing pollen and berries for pollinators and birds.

Regular trimming is essential for maintaining a hedge's shape, density, and health. Most deciduous hedges benefit from one to two trimmings per growing season — typically in early summer after the spring growth flush and again in late summer. Formal (geometric) hedges require more frequent trimming than informal (natural form) hedges. The timing and technique of trimming vary by species, so it is worth learning the specific requirements of your hedge plants.

An aging or overgrown hedge can often be rejuvenated by hard pruning (cutting back to the main stems), though this technique is species-dependent — some species like privet and hawthorn respond well, while others like thuja may not recover from severe cutting. If your hedge has become thin at the base, too wide, or too tall to manage, consult a garden professional about the best rejuvenation strategy for your particular species.
