I'm hoping that some of you experienced spray guys can answer some questions I have with PGR's. I mow lawns and struggle with out of control growth that causes me to either bag clippings or triple cut lawns. I'm losing too much time. We mow Bluegrass Fescue grasses. My question is can you mix Primo with your normal fertilizer application or does it have to be by itself? Are there any precautions that you've seen that I should be aware of? Have you had good success with it? A distrubutor told me that I can't mix it with fert. because it "confuses" the grass by telling it to grow then not grow. Is this true? I appreciate any advice and knowlege you can offer me.
