When planting arborvitae, it is important to space them properly to allow for proper growth and development. The spacing will depend on the specific variety of arborvitae you are planting, as well as the intended purpose for the shrubs. Here are some guidelines to follow when determining the spacing for your arborvitae:
1. Consider the mature size of the arborvitae: Different varieties of arborvitae can vary in size, ranging from dwarf cultivars that reach only a few feet tall to larger varieties that can grow up to 30 feet or more. It is important to research and choose a variety that best suits your space requirements and growth preferences.
2. Allow for proper air circulation: Arborvitae should be spaced apart to allow for adequate air circulation between the shrubs. This helps prevent the development of fungal diseases and promotes overall plant health. As a general rule of thumb, space arborvitae at least half of their mature width apart. For example, if a variety of arborvitae has a mature width of 6 feet, you should plant them at least 3 feet apart.
3. Consider the purpose of the planting: If you are using arborvitae as a hedge or screen, you will want to plant them closer together to achieve a dense and uniform appearance. In this case, you can space them about 2-3 feet apart. However, if you are planting arborvitae as individual specimens or as part of a mixed border, you can space them further apart to allow for individual growth and visual impact.
4. Plan for future growth: It is important to consider the eventual size of the arborvitae when spacing them. While they may look small when initially planted, arborvitae can grow quite large over time. Make sure to provide enough space for their mature size to avoid overcrowding and competition for resources.
5. Take into account site conditions: The spacing of arborvitae should also consider the specific site conditions, such as sunlight, soil fertility, and moisture availability. If planting in a location with less than ideal conditions, such as poor soil or limited sunlight, it may be best to space the arborvitae a bit further apart to allow for better access to resources.
When determining the spacing for arborvitae, consider the mature size of the variety, allow for proper air circulation, consider the purpose of the planting, plan for future growth, and take into account site conditions. By following these guidelines, you can ensure that your arborvitae plants have enough space to thrive and create a beautiful landscape.
