Creating a lush, dense privacy screen with Emerald Green Arborvitae (Thuja occidentalis ‘Smaragd’) is a popular choice for homeowners seeking a natural barrier. These evergreen trees are valued for their vibrant color and easy maintenance. Proper planting, care, and pruning are essential to ensure a healthy, dense hedge that provides privacy year-round.
Choosing the Right Location
Emerald Green Arborvitae thrive in full sun to partial shade. Select a location that receives at least 6 hours of direct sunlight daily. Ensure the area has well-draining soil to prevent waterlogging, which can lead to root rot. Adequate space is necessary for mature height and width, typically reaching 10-15 feet tall and 3-4 feet wide.
Planting Your Arborvitae
Plant in early spring or fall for optimal root establishment. Dig a hole twice as wide as the root ball and the same depth. Gently loosen the roots before placing the plant in the hole. Fill with a mix of native soil and compost, then water thoroughly to settle the soil and eliminate air pockets. Mulch around the base with organic material to retain moisture and suppress weeds.
Watering and Fertilizing
Consistent watering is crucial, especially during the first two years. Keep the soil evenly moist but not waterlogged. Deep watering encourages strong root growth. Apply a balanced, slow-release fertilizer in early spring and again in midsummer. Follow the manufacturer’s instructions for application rates.
Pruning for Density and Shape
Prune in early spring before new growth begins. Use clean, sharp tools to remove dead or diseased branches. To maintain a dense, upright form, selectively trim the outer growth. Avoid shearing the plant into a tight shape, as this can hinder airflow and promote disease. Regular pruning encourages bushier growth and a fuller hedge.
Dealing with Pests and Diseases
Emerald Green Arborvitae can be affected by pests such as bagworms, spider mites, and aphids. Inspect plants regularly and treat infestations promptly with insecticidal soap or neem oil. Diseases like root rot and needle blight can occur if conditions are too wet or crowded. Ensure proper spacing, drainage, and airflow to prevent these issues.
Maintaining Your Privacy Screen
To keep your hedge dense and attractive, perform annual inspections and prune as needed. Remove any dead or damaged branches to promote healthy growth. Consider layering your planting by alternating sizes or varieties to add visual interest while maintaining privacy. Regular care will ensure your Arborvitae remains a lush, effective privacy barrier for years to come.
