Hi Red,
I purchased some MiracleGro rose plant food. It is in granual form to be mixed with water. Have used it in the past and liked it. I have put it now on 4 plants and they all seem to be perking up.
I did do some reading on pruning that I found on Google and feel fairly confident about it now, sounds like it is hard to kill the bushes so I have relaxed.
Now ther is another problem, many of the leaves have small holes in them (not just the ones I am pruning). I am including a picture, it looks like white stuff on them only they are holes with white paper behind them.
