Has anyone tried growing their own tea plant? We bought one from Diggers a year or so ago and it is going reasonably well, although I think perhaps we don’t have it in the best position. We currently have it facing south. I noticed yesterday when we were weeding and mulching it that some if its leaves have developed a narrow pale yellow edge, almost like a variegation. Would this be likely to be a deficiency or perhaps because the soil might not be draining well enough?
