Brown spots on new A.S. Aureum?
I just recieved a one gallon acer shirasawanum 'Aureum' in the mail. It's leaves are just opening and most of the leaves have small round, brown spots on them - toward the outer third of the leaf. At first I took this for a bit of bruising from being shipped, but as more leaves are opening with spots, I'm getting worried.
Each muddy brown spot is between 1-3 mms in diameter and there's maybe half a dozen per leaf. A couple of leaves have no spots, but most do. The stems are all bright green and the bark and graft look good.
I've just emailed the supplier - but I thought I'd run it past my favorite experts as well. I'm sorry I don't have pictures but is this description enough to give you any ideas? Ask away with questions and I'll do my best to clairify.
Thanks in advance,
