The spacing of evergreen trees within the Thuja genus during initial installation significantly influences their subsequent growth, overall health, and effectiveness as a privacy screen or windbreak. Insufficient space can lead to competition for resources, while excessive spacing can result in a less dense barrier. An example includes Emerald Green arborvitae, which typically require closer spacing than larger varieties like Green Giant.
Proper distancing is essential for the long-term vitality and structural integrity of these trees. Adequate airflow between trees reduces the risk of fungal diseases, and sufficient access to sunlight promotes uniform growth. Historically, careful consideration of mature size was not always practiced, leading to overcrowded plantings that required costly corrective measures later in their development.
