Description / Espoma Organic® Soil Acidifier

Acclaimed for turning hydrangeas blue, Espoma® Soil Acidifier is ideal for acid loving plants. Its highly pure organic soil supplementation safely decreases soil pH for months. Controlled-release formulation of 30 percent sulfur safely increases sulfur levels. For each point of pH soil reduction desired, apply six pounds per 50 square feet of soil. Desirable soil pH reduction can be determined through soil testing. To avoid stressing plants, step the pH down gradually. When soil is optimum pH, hydrangeas will offer a bounty of beautifully blue blooms, instead of pink or white blooms indicating higher pH.

Espoma® Soil Acidifier performs better than aluminum sulfate due to higher levels of sulfur, longer lasting formulation, natural ingredients and non-toxicity to plants and animals. Plant burns are prevented through lower salt index, as compared to other soil acidifiers.

Perfect for the Following Acid Lovers:
Evergreens, amaryllis, bleeding heart, aster, ferns, gardenia, hemlock, andromeda, bayberry, camellia, heather, rhododendron, hydrangea, azalea, lily-of-the-valley, lupine, magnolia, holly, huckleberry, raspberry, strawberries, spruce, blueberry, dogwood, leucothoe, marigold, white cedar, inkberry, juniper, mountain ash, oak, pachysandra, fir, heath, mountain laurel, phlox, Pieris, pine and wood sorrel.

We recommend wearing gardening gloves when feeding your plants.

Broadcast Rate:
Apply 12 pounds per 100 square foot for each one point reduction in soil pH desired.
For heavy clay soils increase rate to 15 pounds.
Gradual reduction in soil pH is preferred as dramatic reduction can result in stress.
