Thuja Plant Care Secrets Every Backyard Gardener Should Know

Few trees can rival the grace and resilience of the Oriental Arborvitae. With its evergreen conifer charm and typical pyramidal growth habit, it brings structure and elegance to gardens, landscapes, and driveways. Loved by gardeners in Canada, the USA, and across the world, Thuja is prized for its versatility.

But as easy as it looks, Thuja Plant Care requires an understanding of water, soil, and growth conditions to keep the plant thriving. Let’s explore everything you need to know.

Watering: Balancing Moisture for Healthy Growth

One of the golden rules in Thuja care is adjusting water needs based on age and climate.

• Young Thuja plants need regular watering to establish their roots.
• Mature trees are hardy, and Thuja will take both damp and fairly dry soils once established.
• Specifically, Oriental Arborvitae needs 0.8 cups of water every 9 days when grown in average conditions.

During hot summers, I noticed my Thuja hedges struggled until I increased watering frequency slightly. Consistency, not excess, is key to keeping them green and vibrant.

Soil: The Foundation of Thuja Plant Care

If you want your Thuja to thrive for decades, the right soil is essential.

• Always plant only in well-drained soil to avoid waterlogging.
• Experts recommend ensuring well-draining soil to prevent root rot.
• The best choice is well-draining, slightly acidic to neutral, loamy soil.

Here’s a simple comparison table:

I initially planted one of my Thujas in heavy clay soil, and within months, it showed yellowing tips. After repotting in loamy, well-drained soil, the difference was dramatic.

Light & Climate: Thriving Across Regions

Thuja is known for its adaptability.

• It tolerates hot (zone 11), dry, alkaline, and moist soils, making it suitable for different climates.
• It thrives in full sun but can also handle partial shade.
• Cold winters in Canada and the northern USA don’t deter it, while southern states enjoy its fast growth as a hedge or privacy screen.

This resilience explains why Thuja is one of the most planted ornamental conifers worldwide.

Growth Habits: Understanding the Oriental Arborvitae

The Oriental Arborvitae is an evergreen conifer with a typical pyramidal growth habit. This makes it ideal for structured landscapes, borders, and creating privacy screens.

• It can grow into tall, dense hedges when planted in rows.
• When left to grow naturally, it forms a conical tree with year-round greenery.
• Growth is moderate, making it easier to maintain than fast-growing alternatives.

In my backyard, I’ve used Thuja as both a standalone statement tree and as part of a row to block street noise—it performs beautifully in both roles.

Thuja Plant Care: Tips for Success

Here’s a quick care checklist to keep your Thuja healthy:

• Watering: Remember that young Thuja plants need regular watering, while mature ones can adjust since Thuja will take both damp and fairly dry soils.
• Soil: Always plant only in well-drained soil—ideally, well-draining, slightly acidic to neutral, loamy soil.
• Drainage: Focus on ensuring well-draining soil to prevent root rot.
• Water Needs: Monitor closely—Oriental Arborvitae needs 0.8 cups of water every 9 days on average.
• Climate: It tolerates hot (zone 11), dry, alkaline, and moist soils, making it versatile.
