How to Feed Arborvitae
- 1). Spread the granular fertilizer over the soil using 1/3 lb. of fertilizer for every foot of spread or height of the arborvitae. For example, if the arborvitae tree is 8 feet tall, spread 2 2/3 lb. of granular fertilizer evenly over the soil.
- 2). Scratch the fertilizer into the soil with the hand rake to incorporate it completely. Do not allow the granules to touch the tree as you work them into the soil.
- 3). Water the soil thoroughly immediately after fertilizing. Water until the soil feels evenly saturated.
