If it's me, I'd give it a good drink twice a week, let it bloom, then cut that baby at 1/2 of the bush. Cut all the dead canes and twiggy stuff out. After pruning it down, feed it with a good organic fertilizer. It should reward you with a nice bushy bush and another bumper crop of roses.

What Ken said. The water part is the most important, and then letting it bloom will make it and you happy!

Then don't forget to come back and show those pretty blooms. We would love to see them.
