Care

Thuja Green Giant Care

Provide full sun to partial shade. Prefers full sun, especially in colder climates! Too much shade will cause growth issues. Partial (afternoon) shade may be beneficial when growing in hotter climates. 

Fertilization is suggested, especially if soil is poor. Our slow release fertilizer is a great option. 

Naturally grows in a dense, cylindrical pattern with a pyramidal top section. New growth may be trimmed to shape in late spring, following plant’s natural habit. Keep well-watered after trimming to prevent browning of edges. Do not cut too hard or cut into thick stems, which will result in slow recovery.

More trimming may be required if multiple leaders develop. In this case, select a central leader and trim surrounding growth more drastically to suppress it and allow the chosen leader to take shape. For the best form, do not let the plant decide how it should grow – impose the shape on it once and it should stick.

Water regularly, especially after planting prior to establishment. Attempt to keep soil moist but not wet.

This arborvitae prefers soil that is well draining. 

Space 5'-10 apart to form a hedge. Closer spacing will encourage shorter growth.
