Care Tips:

Sunlight: Plant Degroot's Spire Arborvitae in a location that receives full to partial sunlight. It prefers at least 6 hours of sunlight per day for optimal growth and density.

Fertilizing: While not usually necessary, you can apply a balanced, slow-release fertilizer in early spring to promote healthy growth. Follow the manufacturer's instructions for application rates.
