Keep your evergreens thriving with our Slow Release Evergreen Fertilizer, expertly formulated with a 13-5-6 NPK ratio to deliver long-lasting nutrition. Designed as the best evergreen fertilizer for trees and shrubs, it supports healthy root development, lush foliage, and vibrant year-round growth.

When to Fertilize Evergreens

The best time for evergreen fertilization is in early spring, just before new growth begins, and again in mid-summer if needed. This ensures your evergreen trees have a steady supply of nutrients during their most active growing periods. With our evergreen tree fertilizer, nutrients are released slowly over time, reducing the risk of overfeeding and keeping your landscape consistently nourished.t

How to Fertilize Evergreens

Our fertilizer is designed for easy top-dress application. Simply sprinkle the recommended amount (based on plant size) evenly around the root zone, then water thoroughly to activate. The fertilizer for evergreen trees gradually releases nitrogen, phosphorus, potassium, and essential micronutrients like iron, manganese, and zinc to promote dense foliage and long-lasting color.
