Can You Keep Emerald Green Arborvitae Short? A Comprehensive Guide

The Emerald Green Arborvitae, a popular choice for hedges and screens, is known for its dense, dark green foliage and ability to grow up to 15 feet tall. However, what if you want to keep it shorter? Is it possible, and if so, how? Let's delve into this topic, exploring the Emerald Green Arborvitae's growth habits, pruning techniques, and maintenance tips to help you maintain your arborvitae at a manageable height.

Understanding Emerald Green Arborvitae Growth Habits

Emerald Green Arborvitae (Thuja occidentalis 'Smaragd') is a fast-growing evergreen shrub, typically growing 3-5 feet in height and width per year. It's important to note that while it can be kept shorter, it's not a slow-growing plant. Understanding its growth habits will help you manage its size effectively.

Natural Growth Habits

• Upright Growth: Emerald Green Arborvitae grows upright, with a narrow, pyramidal shape. It maintains this shape naturally, making it easy to keep it short.
• Fast Growth Rate: As mentioned, it grows fast. This means you'll need to prune it regularly to keep it short.
• Evergreen Foliage: It retains its dark green foliage year-round, providing continuous screening and privacy.

Pruning Techniques for Keeping Emerald Green Arborvitae Short

Pruning is the key to keeping your Emerald Green Arborvitae short. Here are some techniques to help you achieve this:

Timing Your Pruning

Emerald Green Arborvitae can be pruned anytime from late winter to early fall. However, the best time to prune for maintaining a short height is late winter to early spring, just before new growth begins. This allows the plant to focus its energy on new growth rather than repairing pruning cuts.

Shearing vs. Selective Pruning

To keep your arborvitae short, you'll likely need to use shearing techniques. Shearing involves cutting back the entire plant to a desired height and shape. This encourages dense, compact growth. However, it's important not to shear too much, as this can stress the plant and make it susceptible to diseases.

Selective pruning, on the other hand, involves removing specific branches to control the plant's size and shape. This is less harsh on the plant but may not result in as dense growth as shearing.

How Short Can You Go?

It's generally recommended not to prune more than one-third of the plant's height at a time. This helps prevent stress and maintains the plant's health. So, if you want to keep your Emerald Green Arborvitae at a certain height, it's best to plant it at that height and maintain it, rather than trying to drastically reduce its size.

Maintenance Tips for Short Emerald Green Arborvitae

In addition to regular pruning, there are other maintenance practices that can help you keep your Emerald Green Arborvitae short and healthy:

Watering and Fertilizing

Emerald Green Arborvitae prefers consistently moist, well-drained soil. Water it deeply once a week, and consider using a slow-release fertilizer in spring to promote dense, compact growth.

Mulching

Applying a layer of organic mulch around your arborvitae can help retain moisture, suppress weeds, and regulate soil temperature. This can encourage healthy, compact growth.

Monitoring for Pests and Diseases

Like any plant, Emerald Green Arborvitae can be susceptible to pests and diseases. Regularly inspect your plants for signs of issues, and treat any problems promptly to prevent them from spreading.

Alternatives to Keeping Emerald Green Arborvitae Short

If you find that keeping your Emerald Green Arborvitae short is too challenging or time-consuming, consider these alternatives:

• Planting in Containers: You can control the size of your arborvitae by planting it in a container. Choose a container that's not too large, as this can encourage the plant to grow too big.
• Using Dwarf Varieties: If you want a shorter, more manageable arborvitae, consider planting a dwarf variety like 'Rheingold' or 'Emerald Green' (dwarf form).

Conclusion

Keeping Emerald Green Arborvitae short is possible with regular pruning and proper care. Understanding the plant's growth habits and using the right pruning techniques can help you maintain your arborvitae at a manageable height. However, it's important to remember that this plant is not a slow-growing shrub, and it may require more maintenance than other plants. Always consider your plant's needs and your ability to care for it before making a decision.
