UN?*V}S/^ L]Hq**K#]O03}dqhwBkA-H_3Eyk9V)8?eEN5x-e{ USE ON: Acid loving shrubs like rhododendrons, hydrangeas, blueberries, dogwoods, holly, gardenias, camellias, and azaleas. Aluminum sulfate should not be used to acidify the soil as large amounts of this material can be toxic to blueberry plants. Plant two or three different cultivars to ensure adequate pollination and fruit set. So, its not ph that matters as much as its the right nutrient combination for the plant. Sulfate when added to water takes the hydrogen out of water and makes an acid. ACID LOVING PLANTS - Aluminum Sulfate is designed to lower soil pH for acid-loving plants such as Azaleas, Camellia, Gardenia, Hemlock, Holly, & more. Established Plants: 2-1/2 cups per plant. The soil can be made more acid by the addition of sulfur, aluminum sulfate, or iron sulfate. A slightly acid pH of about 6 or 6.5 is ideal, because it gives just the right amount of electrical conductivity in the soil, but plants arent nearly as finicky about pH as they are about having the right balance of soil minerals. All rights reserved. Blueberries can withstand 28 F in full bloom. Expert: Angela Price. The sounds of nature fill the air with sounds of celebration for the prospects of what lies ahead.

Stack Overflow for Teams is moving to its own domain! (0-0-0) Aluminum Sulfate lowers soil pH for acid loving plants like azaleas, camellias, gardenias, hemlock, holly, cedar, blueberry, rhododendron, dogwoodturns hydrangeas blue. In addition, aluminum sulfate is toxic to blueberries. Simply impressed to heck! Aluminum Sulfate Great for Hydrangeas Acidifies Soil (lowers pH), corrects high alkalinity CONTAINS: Fertilizer grade Aluminum Sulfate, as Metallic 9.0%. Not for spray application. Use urea if the soil pH is sufficiently low (below 5.0), and ammonium sulfate if the pH is slightly high (above 5.0). First, Mr. Yang says sulfate from potassium sulfate and ammonium sulfate fertilizers is either taken up by the blueberry plants or lost to leaching and does little to change the soil pH. It only takes a minute to sign up. CORRECTS: Excess alkalinity in the soil. Policies bKJ;H]z\&w]FFW I've never seen harm come from following the recommended levels. lj>Y%8z=?Kl8m2-o7*.
