Oberlin from San Antonio Texas writes,
Can pro foam be used with liquid lawn fertilizer?
Pro-Foam can only be used to foam products that are labeled to be used in foaming applications. We are unaware of a liquid lawn fertilizer that is labeled to be used in a foaming application. You should also note that in order for Pro-Foam to make a liquid turn into a foam a foaming device such as the Chapin Poly Foamer would be needed.
