Thank you Andy. Today i decided to do something about the aphids. Used several cloves of garlic and boiled them, than added it to some water in a bottle and sprayed it on the trees and roses that had a problem. I don't like using chemicals and normally i don't mind as long as it is not too much, but this year it is just too much and the fruit trees are suffering under the aphids. I also did bury a few garlic cloves in the pot where the roses are in.
