Establishing a proper fertilizer schedule is essential for the healthy growth of your boxwood hedges after transplanting. Proper nutrition encourages strong root development and vibrant foliage, ensuring your hedge remains lush and resilient.
Understanding Your Boxwood’s Nutritional Needs
Boxwood plants require a balanced supply of nutrients to thrive. The key elements include nitrogen (N), phosphorus (P), and potassium (K). Nitrogen promotes leafy growth, phosphorus supports root development, and potassium improves overall plant health and disease resistance.
Initial Fertilizer Application Post-Transplant
Immediately after transplanting, wait at least four weeks before applying fertilizer. During this period, focus on watering and ensuring the plant establishes its roots. Once the waiting period is over, apply a slow-release, balanced fertilizer with an NPK ratio such as 10-10-10.
First Fertilizer Application
Apply the first fertilizer about four weeks after transplant. Use approximately one pound of fertilizer per 100 square feet of hedge. Spread it evenly around the base, avoiding direct contact with the stems.
Ongoing Fertilizer Schedule
For the next growing season, fertilize your boxwood hedge three times a year: early spring, mid-summer, and early fall. This schedule supports continuous growth and maintains plant health.
Spring Fertilization
Apply a balanced fertilizer in early spring as new growth begins. Use the same amount as the initial application, ensuring even distribution around the base.
Summer Fertilization
Mid-summer, apply a fertilizer high in nitrogen to promote lush foliage. Be cautious not to over-fertilize, which can lead to weak stems and susceptibility to pests.
Fall Fertilization
In early fall, apply a fertilizer with a slightly higher potassium content to prepare the hedge for winter. This helps improve cold tolerance and root strength.
Additional Tips for Fertilizer Application
- Water the hedge thoroughly after each fertilizer application.
- Use slow-release fertilizers to minimize runoff and ensure steady nutrient availability.
- Avoid fertilizing during periods of drought or extreme heat.
- Monitor your hedge for signs of over-fertilization, such as yellowing or browning leaves.
By following this fertilizer schedule and adjusting based on your specific climate and soil conditions, your boxwood hedge will grow strong, healthy, and beautiful for years to come.
