Could be. They shipped it to me a full month before I expected them to ship. It was way too cold (and ridiculously wet) to plant. I've been trying to be good about not overwatering them, too. I called the company today since these spots have been on the leaves and have gotten worse since we got them. Sounds like the call center is in another country (I'll give you one guess as to which country), and the person was only reading from a script. They told me they shipped in a dormant state (hmmm...they had full green, new leaves on them - not dormant), and that they needed to be put in the ground when I got them at end of March.....!!! Ummm, it was still freezing here, raining, and high winds often...not the time to plant young, un-established plants. They need to be established, then they can go through the winter. Well, I sent the company an email...maybe I'll get a response, and maybe it will contain some information.
