Yews are popular evergreen shrubs and trees used in landscaping for their dense foliage and versatility. To ensure healthy growth and vibrant greenery, selecting the right fertilizer and applying it at optimal times is essential. This guide covers the top fertilizers for yews and when to use them for maximum growth.
Understanding Yew Nutritional Needs
Yews require a balanced supply of nutrients, primarily nitrogen (N), phosphorus (P), and potassium (K). Nitrogen promotes lush foliage growth, while phosphorus supports root development and flowering. Potassium enhances overall plant health and disease resistance. Regular feeding ensures yews remain vigorous and healthy.
Top Fertilizers for Yews
1. Slow-Release Granular Fertilizer
These fertilizers provide a steady supply of nutrients over time, reducing the risk of overfeeding. Look for formulations with a balanced NPK ratio, such as 10-10-10 or 12-4-8. Apply in early spring and mid-summer for sustained growth.
2. Liquid Fertilizer
Liquid fertilizers are quickly absorbed, making them ideal for a rapid nutrient boost. Use a balanced liquid feed every 4-6 weeks during the active growing season. Dilute according to package instructions to prevent fertilizer burn.
3. Organic Compost and Manure
Organic options improve soil health and provide slow-releasing nutrients. Incorporate well-rotted compost or manure into the soil in early spring. This method enhances microbial activity and promotes natural nutrient availability for yews.
When to Fertilize Yews
Early Spring
Apply fertilizer as new growth begins to encourage vigorous development. This is the best time to supply nitrogen for lush foliage.
Mid to Late Summer
Use a second application to support continued growth and prepare the yew for the dormant season. Avoid fertilizing late in autumn to prevent new tender growth that could be damaged by cold weather.
Avoid Fertilizing in Late Fall and Winter
Yews are dormant during colder months. Fertilizing during this period can stimulate unwanted growth that may be damaged by frost.
Additional Tips for Healthy Yews
- Ensure proper watering, especially after fertilizing.
- Mulch around the base to retain moisture and regulate soil temperature.
- Prune selectively to maintain shape and remove dead or diseased branches.
- Test soil periodically to adjust fertilization based on nutrient levels.
By choosing the right fertilizers and applying them at appropriate times, you can maximize yew growth and maintain their health and beauty throughout the year.
