Combine 3 ounces sulphate of iron in 5 gallons of water. Five gallons of diluted sulphate of iron covers 1,000 sq. ft. Take precautions when mixing the sulphate of iron with water, as sulphate of iron stains wood, concrete and other non-organic materials.
Pour the sulphate of iron answer right into a hand sprayer, backpack sprayer or watering can for software to the garden. Pump-type sprayers work greatest for giant areas, however small areas could be watered with a bathe spout.
