No, it's in the ground. I did fertilize it thoroughly at the end of May, but that's the last it's had, timed release. We have fertilizer restrictions here, no fert containing Nitrogen to be applied between June 1st and Sept 30. The problem didn't appear until just a few weeks ago.
Do you give your plumies any Magnesium? I could give it an Epsom Salts douse to see if it keeps the new leaves green. I do have high pH well water, but where the Penang Peach is gets watered with rain water from a cistern. Maybe I need to test that rain water for pH and whatever else . . IF the cistern gets low, it is filled automatically with well water so it may have had some well water during July when we got very little rain.
