Hello and Good Day to you Wayne. Thanks for sending in your question. The Knock Out roses are really no different than other roses, in that the optimum pH is 6.5. You are not far off from that and if the roses are performing okay, then I would not get too concerned. Make changes to the soils slowly and carefully if you decide to do so. Making changes too rapidly can really cause problems that take months to fix. Here is a link to one of my articles for you as well >> https://www.gardeningknowhow.com/ornamental/flowers/roses/rose-soil-preparation.htm
