Is Iron Sulphate safe for pets and children
As this is a non-toxic product, it is safe to use where pets and children play. However, iron sulphate is known to stain surfaces. So, it’s recommended to keep pets off treated areas until it has been properly absorbed by the lawn – usually a couple of days or after a heavy downpour. That way it removes any possibility of their fur being stained by the product.
