I've never grown blueberries before, but with a retirement home in central TN (zone 7) with a nice sized yard, I've decided to plant blueberry bushes among other things.. Our soil here is pH 7 so I am going to have to deal with that.

But here's my question: I went to the Nursery and bought 5 bushes. I get them home and start noticing the leaves are covered with rusty colored spots.

Before I bring them back for a refund, I wanted to ask if it is necessary, Are these rusty colors OK and part of the blueberry world? Or is this some fungus on a blueberry bush that should not be sold by a [professional nursery?? Your help would be appreciated!
