Sounds like you planted it correctly with the exception of loosening the burlap on the top of the ball. If you look at the plant the burlap appears to be very tight around the base of it. Another possibility is that you may have spider mites. They are very small and can be difficult to see on the plant. Take a sheet of printer paper out to the plant and hold it under it. Smack the plant a few times to dislodge any of the little critters and you will see them crawling around on the paper. If so, there are miticides that can be used, or you can try soaking the top portion of the plant a few times each day, as they hate the water, they will leave in search of drier pastures.
