How do you deal with customers who think fertilizer burns the lawn. How can I explain that is why they have hired a professional and the application rate has been adjusted? We are applying a slow-release fertilizer that won't activate until we get rain. At the rate we are going, it may be awhile before we get rain. We will be sending out a newsletter to our customers to educate them on dealing with a lawn during drought. I'm hoping to send it out this week.
