How Fast do Emerald Green Arborvitae Grow?

Planting them 2-3 feet apart will create a natural and attractive privacy screen. However, don’t plant them closer than this. Each plant needs enough air circulation to limit the growth of fungi.

Watering and Fertilizing

Emerald Green Arborvitae should be watered twice a week for the first few months after planting. Then, water them about once a week for the next year or so.

While this evergreen will not need regular fertilizing, using a balanced fertilizer, like 10-10-10 can help counteract slow or sparse growth.
