|I bought a blueberry bush (a forked twig, actually), from Wal-Mart a few months ago, and potted it. It was budding when I bought it, but it was too cold to put outside, so I put it in front of the only window I have that receives any sun. Unfortunately, it is above an electric heat register. It was doing well for a month or so, but then the leaves started to turn brown and fall off. I pulled it away from the register, but it continued to either die or go dormant. It warmed up here, so I was able to put it outside, but there is no change. I scraped some bark off the bottom, but it is brown all the way through. Is it possible that it is just dormant? Or did I cook it? It has been outside for about 6 weeks.
