One of the most common problems with Emerald Green Arborvitae is their vulnerability to pests and diseases. But don’t worry! With proper care, you can keep these issues at bay. Regularly inspect the foliage and the surface of the soil for any signs of pests or diseases. If you spot any problems, take immediate action to prevent them from spreading.

In colder climates, the dark green foliage of Emerald Green Arborvitae can turn yellow during the winter months. But rest assured, this is a natural process.

When it comes to fertilizing Emerald Green Arborvitae, less is more. These shrubs have a slow growth rate, so they don’t require frequent fertilization. A single application of a balanced fertilizer in the spring should be sufficient. Avoid using excessive amounts of fertilizer, as it can lead to excessive growth and weaken the shrubs.

Pruning is another important aspect of caring for Emerald Green Arborvitae. Regular pruning helps maintain their shape, controls their size, and improves air circulation. You can prune these shrubs annually in late winter or early spring, before the new growth starts. Simply use a sturdy spade to remove any dead or damaged branches.

Finally, it’s important to know that Emerald Green Arborvitae is an invasive species in some areas. Before planting them, be sure to check the regulations in your region. If you decide to move or remove these shrubs, take extra precautions to prevent their spread. You can dig up the mature shrubs, taking care not to leave any roots behind, or use a pole saw to cut down and remove the unwanted plants.
