How to Use Slow-Release Fertilizers on Boxwood Hedges

by

Maintaining a healthy and vibrant boxwood hedge requires proper fertilization. Slow-release fertilizers are an excellent choice because they provide nutrients gradually, reducing the risk of overfeeding and promoting steady growth. In this guide, we will explore how to effectively use slow-release fertilizers on your boxwood hedges.

Understanding Slow-Release Fertilizers

Slow-release fertilizers are specially formulated to release nutrients over an extended period, typically weeks or months. They come in various forms, including granular, pelletized, and coated options. These fertilizers help maintain consistent nutrient levels in the soil, which is vital for the health of boxwood hedges.

Choosing the Right Fertilizer

Select a fertilizer with a balanced ratio of nitrogen (N), phosphorus (P), and potassium (K). For boxwoods, a formulation such as 10-10-10 or 14-14-14 is often recommended. Ensure the product is labeled as slow-release or controlled-release for best results.

When and How to Apply

Timing

Apply fertilizer in early spring before new growth begins and again in mid-summer. Avoid fertilizing late in the season to prevent new growth that may not harden before winter.

Application Steps

  • Measure the length and width of your hedge to determine the amount of fertilizer needed.
  • Wear gloves and distribute the fertilizer evenly along the base of the hedge.
  • Follow the manufacturer’s instructions for the correct amount to apply based on your hedge size.
  • Lightly water the area after applying to help nutrients penetrate the soil.

Additional Tips

To maximize the benefits of slow-release fertilizers:

  • Avoid over-fertilizing, which can lead to excessive growth and vulnerability to pests.
  • Monitor your hedge regularly for signs of nutrient deficiencies or overfeeding.
  • Maintain proper watering practices to ensure nutrients are absorbed effectively.
  • Combine fertilization with proper pruning to promote dense, healthy growth.

Conclusion

Using slow-release fertilizers on your boxwood hedge is an effective way to promote healthy, consistent growth. Proper timing, application, and monitoring will ensure your hedge remains lush and vibrant throughout the seasons.
