Have any of you guys heard of companies being able to coat fertilize with anything and be considered slow release when really their not?? The reseason I ask is I heard this through a fert. salesman, about Howard Johnson's fert. I'm very pleased with my results but I am having some growth spurts, or so I think so. But, on the other hand the conditions here have been great to grow grass. Rain at least 2-3 days a week with temps from 70-80 every day. What do you guys think?? Has anyone heard of this on slow release ferts.??? Thanks in advance.
