Key Features

ICL Peters 21-7-7 Acid Hammer is a top fertilizer tailored for acid-loving plants, offering a powerful blend of nutrients and pH adjustment capabilities. Its specialized formula ensures optimal growth, vibrant foliage, and enhanced plant health in both residential and commercial settings.

Optimized Nutrient Composition

• 21-7-7 NPK Formula: The high nitrogen content (21%) supports vigorous growth, lush foliage, and overall plant vitality. The balanced amounts of phosphorus (7%) and potassium (7%) promote strong root development and enhance plant resilience.
• Micronutrient Support: Includes essential trace elements that further boost plant health and address nutrient deficiencies often experienced by acid-loving plants.

pH Adjustment

One of the standout features of this fertilizer is its ability to lower the pH of growing media. Many acid-loving plants require soil or growing conditions with lower pH levels to access nutrients efficiently. The Acid Hammer formula gently acidifies the root zone, creating an ideal environment for nutrient absorption.

Specialized for Acid-Loving Plants

Designed specifically for plants that thrive in acidic conditions, such as:

• Azaleas
• Rhododendrons
• Camellias
• Blueberries
• Hydrangeas (for maintaining vibrant blue flowers)

Large 25lb Bag

The 25lb package is ideal for large-scale use, making it a cost-effective solution for nurseries, greenhouses, and expansive gardens. It is also available in bulk quantities (80 per pallet) for commercial operations.

Benefits of Using

• Supports Vigorous Growth: The high nitrogen content drives robust vegetative growth, ensuring plants develop dense, vibrant foliage. This is especially beneficial for ornamental plants and shrubs that depend on lush greenery for visual appeal.
• Improves Root Health: The phosphorus component strengthens root systems, improving nutrient uptake and plant stability. Healthy roots are essential for supporting top growth and long-term plant health.
• Reduces pH Effectively: The Acid Hammer simplifies pH management for acid-loving plants by gradually reducing the alkalinity of growing media. This adjustment improves nutrient availability, preventing deficiencies that can hinder growth.
• Long-Lasting Results: This slow-release fertilizer provides sustained nutrition over time, reducing the need for frequent reapplication. Its consistent performance ensures plants remain healthy throughout their growth cycle.

How to Use

To achieve the best results, it’s important to follow the recommended application guidelines:

Assess Soil Conditions

• Test the pH of your soil or growing media to determine current levels.
