I am really concerned about the Hunter(?) Rugosa rose and the Delphinium as they are turning yellow. As you can see everything in the surrounding area is thriving but in the past days these 2 plants that have looked amazing have began to deteriorate. The spot where the Rugosa is in the middle previously had a young Magnolia tree and the same occured. I did water in some high Nitrogen and Iron in yesteday. Any suggestions would be so welcome, sooner than later please!!!!!
