Hi Ciscoe & Sassy Susan, I’m embarrassed to send this photo…my Stewartia is well established, 10+years, but over the past 5 years it comes on beautifully in the Spring and then by late June the leaves turn rust colored and dry out…regardless of how often I water. My question is whether this is from drought, disease, deficiency, sunburn or bad mothering?! Your friend in Anacortes, Margaret
