There is no question that the problem is alkalinity related. I amazed my neighbors Red Oak has gotten as big as it has. Most of the time you end up with stunted growth and they never get near that size. My neighbors is going down hill more quickly then the prior years and I do not expect it to survive much longer. I also have a Live Oak the builder planted that is also not a tradition Escarpment Live Oak or a mixed Escarpment/Coastal that thrives in alkaline soil. It's some neutral/alkaline soil loving variety. My tree get watered by my nutrient rich septic water seven days a week and it has helped minimize the chloratic symptoms. The Live Oak soil PH issues are pretty rare compared to the wide spread Red Oak issues.
