Rhododendrons, Azaleas, Blueberries, Mountain Laurel, Holly and Blue Hydrangea thrive best in acidic soil. If your soil is not naturally acidic, mix in 1/2 to 3/4 peat moss with the planting soil. At the same time, mix in thoroughly 6oz. (12 teaspoons) of Ferrous Sulfate to a 3' x 3' area for each plant. Fast, safe and not toxic. Some soil acidifiers are considered toxic to plants and take up to a year to change the PH level of the soil. Soils vary, however a rule of thumb is to apply area around each plant. For example, if you want to change PH 6.5 to PH 5.5, apply 12 oz. In a 3' x 3' area around the plant and water well. Keep plants well watered.
