Why Your Thuja Plant Is Growing Sideways

If you have noticed that your Thuja plant is growing sideways instead of upright, you may be wondering what could be causing this unusual growth pattern. Thuja plants, also known as arborvitaes, are popular evergreen trees and shrubs that are native to North America. They are commonly used as hedges or privacy screens due to their dense foliage and fast growth rate. However, when a Thuja plant starts growing sideways instead of vertical, it can be a cause for concern. In this article, we will explore some possible reasons why your Thuja plant may be exhibiting this growth pattern and discuss ways to rectify the issue.

Insufficient Sunlight

One of the most common reasons why a Thuja plant may grow sideways is due to insufficient sunlight. Thuja plants require full sun to thrive and reach their full potential. If your plant is not receiving enough sunlight, it may start to stretch towards the available light source, resulting in a sideways growth pattern. This is especially common when Thuja plants are grown in shady or crowded areas.

To address this issue, consider relocating your Thuja plant to a spot where it can receive at least 6 hours of direct sunlight every day. Trimming nearby trees or shrubs that may be casting shade on your Thuja can also help improve its sun exposure.

Poor Soil Conditions

Another factor that can cause a Thuja plant to grow sideways is poor soil conditions. Thuja plants prefer well-draining soil with a slightly acidic pH level. If the soil in which your plant is growing is compacted or lacks proper drainage, it can lead to stunted root growth and result in the plant tilting or leaning to one side.

To improve soil conditions, consider amending the soil with organic matter such as compost or peat moss. This will help improve soil structure and drainage capabilities, allowing the roots to grow strong and upright. Additionally, regular watering practices are essential to ensure that the soil remains moist but not waterlogged.

Improper Pruning Techniques

Improper pruning techniques can also contribute to a Thuja plant growing sideways. If the plant is pruned too heavily on one side or if the branches are unevenly trimmed, it can result in an imbalanced growth pattern. The plant may lean towards the side with more foliage or branches, causing it to grow sideways.

When pruning your Thuja plant, it is crucial to maintain a balanced shape by trimming evenly on all sides. Avoid removing too much foliage from one side and ensure that the branches are evenly distributed. Regular pruning will help promote vertical growth and prevent the plant from leaning or tilting.

Wind Damage

Strong winds can cause damage to Thuja plants, especially if they are exposed and not adequately protected. Constant exposure to strong winds can push the plant in one direction, causing it to grow sideways over time. This is more likely to happen in areas with open landscapes or coastal regions where wind speeds are higher.

To protect your Thuja plant from wind damage, consider installing windbreaks such as fences or plant shrubs around it to create a barrier. This will help reduce the impact of strong winds and allow your plant to grow upright.

Pests and Diseases

In some cases, pests or diseases can lead to a Thuja plant growing sideways. Insect infestations, such as bagworms or spider mites, can weaken the plant’s structure and cause it to lean or tilt. Similarly, certain diseases like root rot or stem canker can affect the root system and disrupt normal growth.

If you suspect that pests or diseases are causing your Thuja plant to grow sideways, consult with a professional arborist or horticulturist for proper diagnosis and treatment options. They will be able to identify the specific issue and recommend appropriate measures to address it.

Conclusion

If your Thuja plant is growing sideways, it is essential to identify the underlying cause and take appropriate action to rectify the issue. Whether it is due to insufficient sunlight, poor soil conditions, improper pruning, wind damage, or pests and diseases, addressing the root cause will help your Thuja plant regain its upright growth pattern. With proper care and attention, you can ensure that your Thuja plant thrives and adds beauty to your landscape for years to come.
