What happens if arborvitae are planted too close together?

When homeowners are looking to create a dense screen in their yard, they often make the mistake of planting arborvitae too close together. While the intention is to achieve a fast-growing and full hedge, the consequences of overcrowding can be detrimental to the health and growth of these plants.

One of the main issues with planting arborvitae too close together is the competition for resources. As the plants grow, they will start to compete for essential elements such as light, root space, water, and nutrients. This competition can result in stunted growth, weakened plants, and an overall decline in health.

In terms of light, arborvitae planted too closely together will cast shadows on each other, restricting the amount of sunlight each plant receives. Sunlight is crucial for photosynthesis, the process by which plants convert light into energy. Without sufficient sunlight, the arborvitae may struggle to produce the energy needed for growth and may become thin and sparse.

Root space is another critical factor to consider. When arborvitae are planted too close together, their root systems can become tangled and compacted. This can lead to root crowding, where the roots of neighboring plants intertwine and struggle to access necessary water and nutrients from the soil. As a result, the growth and overall health of the arborvitae can be negatively affected.

Water availability is also impacted when arborvitae are planted too close together. When plants are densely packed, their leaves and branches create a barrier that can prevent rainwater from reaching the soil. This can lead to water runoff and inadequate moisture for the roots. Additionally, the limited root space mentioned earlier means that the plants may have to compete for the available water, further stressing their growth and vitality.

Nutrient deficiency is another consequence of overcrowding. When arborvitae are planted too close together, the soil’s nutrient supply may not be sufficient to support the growth of multiple plants. As the plants compete for nutrients, they may exhibit signs of deficiency, such as yellowing leaves, stunted growth, and overall poor vigor.

It is important to consider the final height of arborvitae when planting them. These trees can reach significant heights, and if planted too close together, they may end up overcrowding the space and obstructing views or encroaching on neighboring structures. Proper spacing is crucial to allow each plant to reach its full potential without interfering with its surroundings.

In my personal experience as a gardening and landscaping expert, I have witnessed the consequences of planting arborvitae too closely together. I have seen instances where homeowners were eager to create a dense hedge quickly, only to end up with a row of stunted and unhealthy plants. It is essential to emphasize the importance of proper spacing and allowing enough room for each arborvitae to thrive.

To avoid these issues, it is recommended to follow spacing guidelines provided by experts or nurseries when planting arborvitae. This will ensure that each plant has enough room to grow, access to adequate resources, and the ability to develop into a healthy and beautiful addition to your landscape.
