EYAEAYO 2-pound aluminum sulfate is a fast-acting, high-purity soil amendment specifically formulated to lower soil pH levels and help hydrangeas produce vibrant blue blooms. Ideal for gardeners looking to customize their hydrangea colors, this water-soluble powder delivers aluminum ions directly to the soil— a key nutrient that hydrangeas absorb to transform pink or purple blossoms into rich, vivid blue flowers.
Suitable for acid-loving plants beyond hydrangeas, including azaleas, rhododendrons, camellias, and blueberries, it effectively acidifies alkaline or neutral soil, creating the optimal growing environment (pH 5.0–5.5) for these plants to thrive. The easy-to-apply formula can be mixed into the soil during planting or dissolved in water for a liquid drench application. For best results, apply in early spring before new growth emerges, and reapply every 4–6 weeks during the growing season to maintain consistent soil acidity.
Free from harmful additives, this 2-pound package provides ample product for treating multiple hydrangea bushes or acid-loving plant beds. Packaged in a resealable bag to prevent clumping and moisture damage, it’s a reliable choice for both novice and experienced gardeners aiming to achieve stunning blue hydrangeas and healthy acid-loving plants.
