Some Essential Tips For Better Growth Of Thuja Emerald Hedges

If you’re looking to enhance the growth of your Thuja emerald hedges, we’ve got you covered with some essential tips. Following these suggestions, you can guarantee that your hedges will flourish, creating a stunning and vibrant green boundary in any landscape. So, let’s dive in and discover how to make your Thuja emerald hedges thrive.

1. Planting the Hedge

When planting the Thuja Emerald hedge plants, it is important to carefully select a suitable location that receives full to partial sunlight. These hedges require well-drained soil, so it’s important to ensure the planting area has good drainage. To properly plant the Thuja Emerald hedge, dig a trench slightly wider and deeper than the root ball. Then, place the plants in the trench, making sure they are evenly spaced for proper growth. After planting, gently backfill the trench with soil, firming it around the roots. Water the newly planted Thuja Emerald hedge thoroughly to ensure successful establishment. Follow these steps for successful planting and establishment of your hedge.

2. Watering

Thuja Emerald hedges need to be watered regularly, particularly in the first year after they are planted. It is important to water them deeply and evenly, ensuring that the soil is moist but not overly saturated. In periods of hot and dry weather, it is necessary to increase the frequency of watering to keep the hedges hydrated. Although as the hedges grow and mature, they become more tolerant to drought conditions, it is still crucial to keep an eye on the moisture levels in the soil and provide additional watering when necessary. By maintaining proper watering practices, the Thuja Emerald hedges will thrive and remain healthy throughout their lifespan.

3. Mulching

Mulching around the base of Thuja Emerald hedges has many benefits. It retains soil moisture, suppresses weed growth, and regulates soil temperature. Applying organic mulch like wood chips or bark reduces water evaporation and keeps the soil moist for longer. Mulching also acts as a barrier against weed seeds, saving time and effort in weed control. It helps maintain a stable and favorable environment for the roots by regulating soil temperature. When mulching, it is important to keep a gap between the trunk and the mulch to prevent rot or fungal issues. Overall, mulching promotes the health and vitality of the hedges.

4. Pruning and Trimming

Regular pruning and trimming play a crucial role in upholding the desired shape and density of your Thuja Emerald hedges. It is imperative to promptly prune any branches that are dead, damaged, or affected by disease as soon as you become aware of them. When making these cuts, it is important to ensure that they are clean and made just above a healthy bud or lateral branch. For optimal hedge shape, it is advised to trim them once or twice yearly. Early spring and late summer are the finest times to visit. Avoid pruning during hot months to prevent plant stress. These practices maintain healthy, well-kept, visually pleasing Thuja Emerald hedges.

5. Fertilizing

Regular fertilization is necessary for optimal growth and health of Thuja Emerald hedges. It is recommended to fertilize them annually using a balanced slow-release fertilizer. This type of fertilizer releases nutrients gradually, ensuring a consistent supply of nourishment. Follow the manufacturer’s instructions when applying the fertilizer in early spring. Avoid over-fertilization, as it can weaken growth and increase susceptibility to diseases. Striking a balance is crucial for providing the right amount of nutrients to support healthy and robust growth in Thuja Emerald hedges.

6. Pest and Disease Control

Regularly monitor Thuja Emerald hedges for pests and diseases. Common pests include aphids, spider mites, and fungal infections. Early detection is crucial for effective control. Seek advice from a local nursery or professional landscaper if you notice any issues with your hedges. These experts can identify the problem and offer suitable treatment options to ensure hedge health. Consulting with them will guide you on maintaining hedge well-being. Professionals can restore and enhance hedge beauty, even if it’s a pest infestation, disease, or lack of care. Reach out to them for expert advice and assistance in preserving hedge health.

7. Winter Protection

In harsh winter regions, taking care of your Thuja Emerald hedges is important to ensure their survival. One crucial step is to provide deep watering before the first frost. This ensures that there is enough moisture for the dry winter season. Additionally, mulching around the plants helps insulate the roots, protecting them from sudden temperature changes. You might also want to consider using a windbreak or burlap screen to shield your hedges from cold winds and excessive snow accumulation. By taking these measures, you can ensure that your Thuja Emerald hedges are well-protected during winter and will last for a long time.


Proper care is crucial for thriving Thuja Emerald hedges. Choosing the right location with adequate sunlight and well-drained soil is crucial. Watering deeply and consistently, without overwatering, is important. Regular pruning and trimming remove dead or damaged branches for healthy growth and a neat appearance. Applying a balanced, slow-release fertilizer in spring provides the necessary nutrients. Regular monitoring for pests and diseases allows for prompt treatment. In colder regions, winter protection, like burlap wrapping or mulch insulation, is necessary. Following these guidelines ensures the survival and beauty of your Thuja Emerald hedges.
