Key Features

Espoma is known for its organic and eco-friendly gardening products. This acidifier maintains the brand’s high quality and safety, giving gardeners a safe way to lower soil pH without harming human health or the environment.

  • Natural & Organic Ingredients: Manufactured with raw elemental sulfur and gypsum and no fillers or sludge. It’s a clean, honest plant food meant to improve the soil.
  • Safe Alternative to Aluminum Sulfate: Most soil acidifier products are a form of aluminum sulfate which can be toxic to plants and cause aluminum to accumulate in the soil. Espoma has managed to sidestep this issue with its sulfur-based mix, which is thus safer in the long term for soil health.
  • Long-Lasting Results: This acidic raw material will help in encouraging the uptake of nutrients by plants thanks to its 30% sulfur concentration.

Description

The Espoma 6 lb Soil Acidifier with Sulfur is a product that the gardener can rely on to establish a proper soil environment to grow acid-loving plants. It naturally and effectively reduces the soil pH levels, allowing hydrangeas to produce dramatic blue flowers and facilitating the maximum growth of blueberries, hollies, gardenias and others. This soil acidifier is eco-friendly and high-performance because it is safe, organic, and long-lasting.

Benefits

The acidity of the soil is extremely important for plant growth and for their well-being. Espoma Soil Acidifier is the most effective soil acidifier available, enhancing both ornamental and edible landscapes.

  • Hydrangeas in Full Color: To turn the pink blossoms of these hydrangeas to bright blue, gardeners can lower the soil’s pH. This transformation highlights the beauty of the plant and offers more diversity in landscape designs.
  • Blueberries and Other Acid-Lovers: Fruits like blueberries require an acidic soil to facilitate nutrient uptake. Similarly, additions of this product can also create desired lower pH values for shrubs such as rhododendrons, camellias, and hollies.
  • Ferns, Azaleas, and Gardenias: A variety of acid loving plants, from delicate ferns to showy azaleas, will be happy in a soil that has been conditioned using Espoma’s acidifier.

How to Apply

Espoma Soil Acidifier is easy to use, but remember slowly amending the soil is the key. The product provides effective control without causing undue stress to the plant, allowing the flexibility to treat smaller or larger gardens.

  • New Hydrangeas and Blueberries: Use 1¼ cups per plant in spring, apply evenly to the drip line before watering.
  • Established Plants: Apply 2½ cups per plant. Repeat every 60 days until the desired color or dirt condition is reached.
  • Containers: For potted plants, add 1 tablespoon per 4 inches of pot diameter to the soil. This maintains the acidity in small pots.
  • Broadcast Application: When treating a larger area, apply 12 lbs per 100 sq. ft. to decrease the soil pH by one point. On heavy clay increase the above rate of application to 15 lbs.

Science Behind Bloom Color

Soil pH greatly affects the color of hydrangeas. Espoma Soil Acidifier is an all natural and highly effective way to lower the pH of soils or compost.

  • Deep Blue Blooms: Obtained by decreasing the soil pH to approximately 4.5.
  • Muted Blue: Found in soil with a pH of around 5.0.
  • Violet-Blue Shades: Discovered a bit higher, at a pH of 5.5.

Eco-Friendly

Espoma has been focused on sustainability for generations and this soil acidifier is not the exception. Made in solar powered factories, it is representative of the company’s commitment to reducing its environmental impact.

  • Sustainable Production: Espoma Soil Acidifier is an all-natural EPA compliant product.
  • Clean Formula: Unlike the ones from industrial products, fillers and harmful additives, keep the soil health and save the entire ecosystem.

Summary

More than a soil acidifier, the Espoma 6 lb Soil Acidifier with Sulfur is a total solution for gardeners who prefer effectiveness, safety, and sustainable practices. By naturally reducing the soil’s pH, it allows acid-loving plants to take full advantage of this natural soil amendment, from hearty azaleas to bright, fruit-bearing blueberry bushes.

Due to its simple, organic ingredients, ease of application and eco-friendly production, Espoma Soil Acidifier continues to be a rare but invaluable product to the passionate and earth-friendly gardener.
