Arbor Vitae Fertilizer: 15 Secrets for a Thriving Green Hedge

When it comes to evergreen shrubs, arborvitae reigns supreme. These versatile plants are known for their dense foliage, columnar shape, and year-round appeal. However, to maintain their vibrant green color and healthy growth, arborvitae require proper fertilization. Here's everything you need to know about arbor vitae fertilizer, including the best time to fertilize, what to look for in a fertilizer, and tips for avoiding common mistakes.

Why Fertilize Arborvitae?

Fertilizing arborvitae provides the essential nutrients they need for optimal growth and health. Nitrogen promotes leaf development and produces a deep green color, while phosphorus supports root growth and flowering. Potassium helps regulate water uptake and reduces the risk of disease.

Best Time to Fertilize Arborvitae

The ideal time to fertilize arborvitae is early spring, just as new growth begins. This allows the plant to absorb nutrients throughout the growing season. You can also fertilize in late fall, after the plant has gone dormant. Avoid fertilizing in mid-summer, as this can encourage excessive growth and stress the plant.

Choosing the Right Fertilizer for Arborvitae

When selecting an arborvitae fertilizer, look for a balanced formula with a ratio of 10-10-10 or 12-12-12. This will provide ample nitrogen, phosphorus, and potassium for all-around health. Slow-release fertilizers are recommended, as they provide nutrients gradually over an extended period.

  2. Calculate the amount of fertilizer to apply based on the manufacturer's instructions. A general rule is to apply 1 pound of fertilizer for every 100 square feet of canopy area.
  3. Spread the fertilizer evenly around the base of the plant, keeping it 6-12 inches away from the trunk.
  4. Water the plant deeply to help dissolve and distribute the fertilizer.

4 Common Mistakes to Avoid

Why Fertilize Arborvitae?

  1. Overfertilizing: Applying too much fertilizer can burn the roots and damage the plant. Stick to the recommended dosage and avoid applying fertilizer more than once every 3-4 months.
  2. Fertilizing at the wrong time: Fertilizing arborvitae in mid-summer can promote unwanted growth and stress the plant.
  3. Using a fertilizer with too much nitrogen: Nitrogen-heavy fertilizers can stimulate excessive leaf growth, making the plant more susceptible to pests and diseases.
  4. Not watering after fertilizing: Watering after fertilizing helps dissolve and distribute the nutrients throughout the soil.
