Mature Width and Height
A growing emerald green thuja will continue to grow at a standard rate until it reaches maturity. The smallest mature thuja reach heights of approximately 6 feet, while the largest mature thuja reach upwards of 15 feet. The width or spread of a mature thuja depends largely on the space given to it. Some only spread to 3 feet, while the widest sometimes spread up to 6 feet.
Emerald green thuja grow in full sun to part shade, but thrive in full sun. Moist, slightly acidic and well-drained soil works best for these trees. They need at least 3 feet between one another in order to grow at a strong rate.
