Q.How Do I Get Rid Of Take All Root Rot In My Lawn?
I have had my lawn disease identified by the Texas A&M University Plant Disease Identification Lab as Take All Root Rot. I tried a recommended funguscide but it didn’t work. The Extension Service recommended I adjust the pH of my lawn soil to be slightly acidic. How do I adjust a strongly bacic soil to be slightly acidic?
