Perfect for Acid-Loving Plants

Many popular landscape plants struggle when soil pH becomes too alkaline, making it difficult for roots to absorb essential nutrients. Jack's Classic Acid Special helps create a more favorable growing environment by supplying nutrients that acid-loving plants require for healthy development.

• Azaleas
• Rhododendrons
• Hydrangeas
• Blueberries
• Camellias
• Citrus Trees

Helps Correct Iron Deficiency & Leaf Yellowing

The elevated iron and sulfur content helps combat chlorosis, a common condition that causes leaves to yellow while veins remain green. By improving nutrient availability and supporting proper plant metabolism, Jack's Classic Acid Special encourages vibrant green foliage and stronger overall growth.

Excellent for Foundation Plantings

Homes with concrete foundations, sidewalks, and driveways can gradually raise surrounding soil pH due to limestone leaching. This can create challenges for acid-loving plants growing nearby. Jack's Classic Acid Special is an excellent solution for maintaining healthy growth in these difficult planting environments.
