Roots Holly Boost™ 6-4-6 Fertilizer – 50 lb

Roots Holly Boost™ 6-4-6 is a premium granular fertilizer designed specifically for acid-loving plants such as hollies, azaleas, rhododendrons, camellias, and evergreen shrubs. This professional-grade fertilizer provides a balanced blend of slowly available natural nutrients that promote strong growth, vibrant foliage, and healthier root development.

Unlike many organic fertilizers, Roots Holly Boost contains no manure or sewage-based ingredients, meaning you get powerful plant nutrition without unpleasant odors. The formula is enhanced with 5% elemental sulfur to gently lower soil pH, creating the ideal growing environment for plants that thrive in acidic soil conditions.

In addition to essential nutrients, Roots Holly Boost includes beneficial rhizosphere bacteria that help convert nutrients into forms plants can easily absorb. Added humic acids improve nutrient uptake and support overall soil health. The result is a cleaner, low-dust fertilizer that feeds plants gradually while improving the soil ecosystem around your landscape plants.

A single 50 lb bag covers up to 15,000 sq. ft., making it a great option for homeowners, landscapers, and garden centers looking to maintain thriving ornamental beds and foundation plantings.
