How much & how often can i add 20% Iron Sulfate to each Blueberry Bush to lower the P/H , i have added some Elemental Sulfur, about 2 months ago & Pine bark Fines and pine Mulch . I keep checking the P/H but everything is very slow in falling, so i bought some 20% Iron Sulfate... So i need to know how to apply it, i think 2 Tbsp's per Bush , per month is correct? But i am not for SURE? Can you help me? Thank You Jerry
