My neighbour has recently had a pretty bad attack of rose sawfly and now it's spread into my garden.
I have a run of climbing rose about 25 feet long and several shrubs dotted about the borders in my back garden. All are showing signs with severely rolled leaves. I don't like to use chemicals and have picked off all the affected leaves. However they are looking pretty bare after this. I've also sprayed with garlic barrier spray.
Couple of questions, what can I do to stop it spreading to my terrace (about 30 yards away) and my front garden (about 40 years away) plus how can I reinvigorate the large plants I've pretty much denuded.
