Not sure what to do for next year. I'm hoping it is just environmental factors and not a decrease in the efficacy of the product. FWIW I use a fert coated with Merit. Have used it the past two years with great success. 100% effective until now.
So one minor failure. That makes it what...99.8% effective?
Are you expecting 100% results each application given all the possibilities and variables involved?
