Folks: Have so far found other comments re: what seem to be similar situations with arbutus trees (we're not quite sure of our specific type) encouraging, but am still wary of significant yellowing in the leaves of our tree. We planted it in April - very well-drained soil (dirt deep in the hole was dark, but not necessarily moist when we planted it). In the past month, the leaves in the inner parts of most branches have turned yellow, and in some cases brown. Has been more damp than usual here on the coast (low fog and in some cases marine layer precip), but the sun has been out most days, drying the ground pretty well. There did seem to be new growth sprouting for awhile, but not so sure any more. We heavily watered it when we first planted it, but trailed to once per week of deep watering. In the past month, the tree has been sparsely watered (I think). Below are some pics of the tree. Would love some observations re: potential causes for the yellowing and whether or not we should worry - and if yes, then what we might like to do for it. Thanks in advance.
