Per the product label: Recheck the pH two weeks after application. If needed, reapply only to those areas where the desirable pH is required to maintain vigorous plants. Hi-Yield Aluminum Sulfate helps create an acid soil condition which is desirable for hydrangeas (blue). By acidifying the soil, Hi-Yield Aluminum Sulfate can maintain or change the color of Hydrangea flowers. Blue Hydrangeas require Aluminum as an acidifier, to retain their blue color. They should not be fed a Phosphate fertilizer due to the fact that it has a tendency to “tie-up” Aluminum.
Hi-Yield Aluminum Sulfate is not labeled for use on anything edible. It is only labeled for use on trees and shrubs.
Per the product label for Hi-Yield Aluminum Sulfate: Use 1 lb. per 3 ft. of height. Mix 1 lb. in 5 gallons of water and apply at the drip line of the Shrub. HI-YIELD ALUMINUM SULFATE can also be spread dry around the drip line and watered in. If you spread dry we would recommend you use 2/3 lb per 2 ft of height and then water in with sufficient water or you could use the mix of Ferti-Lome Acid Loving Water Soluble Plant Food 31-11-11 following the rates on its label.
To create more acidic soil for acid-loving plants, you would use Hi-Yield Aluminum Sulfate for shrubs at a rate of 1 lb. per 3 feet of height per 5 gallons of water. For trees, use 1 lb per inch of trunk diameter per 5 gallons of water.
