How Fast Does The Emerald Green Arborvitae Grow

How Fast Does the Emerald Green Arborvitae Grow? A Comprehensive Guide

The Emerald Green Arborvitae (Thuja occidentalis 'Smaragd') is a popular choice for landscaping due to its vibrant green color, dense foliage, and relatively low maintenance. But one of the most frequently asked questions about this beautiful evergreen is: how fast does it grow? The answer, as with most plants, isn't a simple number. Growth rate depends on several factors, and understanding these will help you manage expectations and ensure your Emerald Green Arborvitae thrives.

Understanding Emerald Green Arborvitae Growth Rates

While there's no single definitive answer to the speed of Emerald Green Arborvitae growth, a general expectation is a growth rate of 12 to 15 inches per year. However, this is just an average. In optimal conditions, it might grow slightly faster, reaching up to 24 inches annually. Conversely, less favorable conditions can significantly slow growth, resulting in only a few inches of new growth each year.

Factors Affecting Growth Rate

Several factors influence how quickly your Emerald Green Arborvitae will grow. These include:

• Sunlight: These arborvitae prefer full sun to partial shade. While they can tolerate some shade, insufficient sunlight will significantly hinder growth. Plants in full sun typically exhibit the fastest growth rates. Conversely, those planted in deep shade might become leggy and sparse.

• Soil: Well-drained, slightly acidic soil is ideal. Poorly draining soil can lead to root rot, severely impacting growth and even killing the plant. Amend heavy clay soils with organic matter to improve drainage and aeration. Regular soil testing can help determine if amendments are necessary to achieve the optimal pH level.

• Water: Consistent watering, especially during the first year after planting, is crucial. Young plants need regular moisture to establish a strong root system. Established plants are more drought-tolerant, but consistent watering during dry spells will promote faster growth. Avoid overwatering, which can lead to root rot. Mulching around the base of the plant helps retain soil moisture and suppresses weeds.

• Fertilization: While not strictly necessary, fertilizing your Emerald Green Arborvitae can promote faster growth. Use a slow-release fertilizer specifically formulated for evergreens, following the package instructions carefully. Over-fertilizing can be detrimental, potentially burning the roots. Applying fertilizer in early spring is generally recommended.

• Climate: Temperature and precipitation play a significant role. Warmer climates with ample rainfall generally support faster growth. Conversely, cold winters or prolonged droughts can slow growth. Consider your local climate and adjust watering and fertilizing practices accordingly.

• Pruning: Proper pruning helps maintain the shape and health of the plant, indirectly influencing growth. Regularly removing dead or damaged branches promotes new growth. However, excessive or improper pruning can stress the plant and negatively impact its growth rate. Learn proper pruning techniques to avoid causing damage. Spring is generally the ideal time for pruning.

• Planting: Proper planting techniques are essential for healthy growth. Ensure the root ball is properly hydrated before planting. Dig a hole twice as wide as the root ball and plant at the same depth as it was in its container. Firmly pack the soil around the roots.

• Pest and Disease: Infestations of pests or diseases can significantly slow or even halt growth. Regularly inspect your plants for signs of pests or diseases and take appropriate action if necessary. Maintaining a healthy plant through proper care reduces the likelihood of pest or disease problems.

Expected Size and Maturity

Understanding the growth rate helps you plan your landscaping effectively. With an average annual growth of 12-15 inches, an Emerald Green Arborvitae planted as a small sapling can reach a mature height of 4-6 feet within 3-5 years. However, remember this is an average, and actual growth may vary. Eventually, under ideal conditions, they can reach a mature height of 12-15 feet and a spread of 3-4 feet. This mature size is typically achieved within 10-15 years.

Tips for Encouraging Faster Growth

If you want to encourage faster growth in your Emerald Green Arborvitae, consider these tips:

• Choose a sunny location: Plant in an area that receives at least 6 hours of direct sunlight per day.

• Improve soil drainage: Amend heavy clay soils with organic matter like compost to improve drainage and aeration.

• Water regularly: Provide consistent watering, especially during dry periods. Use a soaker hose or drip irrigation to water the root zone directly.

• Fertilize appropriately: Apply a balanced, slow-release fertilizer formulated for evergreens in early spring.

• Mulch the base: Apply a layer of organic mulch around the base of the plant to retain soil moisture and suppress weeds.

• Protect from pests and diseases: Regularly inspect the plants for signs of pests or diseases and take appropriate action if necessary.

Troubleshooting Slow Growth

If your Emerald Green Arborvitae isn't growing as quickly as expected, investigate potential problems:

• Insufficient sunlight: Relocate the plant to a sunnier location if necessary.

• Poor soil drainage: Amend the soil to improve drainage.

• Inadequate watering: Adjust your watering schedule to ensure consistent moisture.

• Nutrient deficiencies: Apply a balanced fertilizer in early spring.

• Pest or disease infestation: Identify and treat any pest or disease problems.

• Root damage: Ensure the plant wasn't damaged during planting or transplantation.

Long-Term Care and Maintenance

Even with fast growth, proper ongoing care is essential for a healthy, thriving Emerald Green Arborvitae. This includes:

• Regular Watering: While mature plants are more drought-tolerant, consistent watering, especially during dry periods, promotes healthy growth.

• Annual Fertilization: Applying a slow-release fertilizer in early spring helps replenish nutrients in the soil.

• Pruning: Light pruning in late winter or early spring helps maintain shape and remove dead or damaged branches.

• Pest and Disease Monitoring: Regularly inspect for signs of pests and diseases and take immediate action if necessary.

• Mulching: Maintain a layer of organic mulch around the base of the plant to retain moisture and suppress weeds.

Conclusion

The growth rate of an Emerald Green Arborvitae is influenced by many factors. While you can expect around 12-15 inches of annual growth on average, understanding these influencing factors allows you to create the optimal growing conditions for a lush and healthy plant. By providing proper sunlight, soil, water, and nutrients, you can encourage faster growth and enjoy the beauty of this popular evergreen in your landscape for years to come. Remember that patience is key; even with optimal care, significant growth takes time. Consistent care and attention to detail will yield the best results.
