ALUMINUM SULPHATE 
Azaleas, Rhododendrons, Blueberries, Cornus Florida, Heather, Kalmia 
and many other plants require an acid soil. Acid-forming organic matter, 
such as well rotted oak leaves helps to increase acidity. Aluminum Sulphate 
is a good chemical for increasing soil acidity by using 14 to 14 pound per 
square yard. Also used for turning hydrangeas blue. 10 lbs. $1.50; 50 lbs. 
$4.50; 100 lbs. $7.50.
