Espoma Organic Soil Acidifier (6 lb) is elemental sulfur that lowers soil pH gradually and safely for acid-loving plants. If your soil test shows pH above 5.5 and you're growing blueberries, azaleas, rhododendrons, or hydrangeas, this is how you bring it down. Also turns pink hydrangeas blue — hydrangea color is controlled by soil pH. Works gradually over weeks, which is safer than fast-acting acidifiers that can shock plants. Available in Galion, OH.
