I have Munstead Wood for 6 years as own-root. My Munstead Wood has more blooms than the rose park's grafted-on-Dr.Huey, so it does better as own-root. It likes alkaline minerals. I almost killed it when I put too much acidic gypsum to break up my alkaline clay, and had to replace the soil with bagged alkaline clay before it pumped out 40+ blooms per flush. It needs high potassium fertilizer before the scent can be maximized. Potassium helps with thicker stems and more blooming. I use sulfate of potash with my alkaline tap water, but if I have too much acidic rain, I soak high-potassium-pea gravel into acidic rain water to supply potassium.
