Hello, All. My Knockout roses are reviving thanks to drier weather but, sadly, I now notice borers all along my forsythia hedge. HELP! I know it is late in the season but is there anything I can do to save them?
Maryland, United States
I have read about systemic 'Merit' insecticide. It is Imidacloprid and I am wondering if I should put it down now and then cut the forsythia to the ground and hope for the best.
Any ideas would be greatly appreciated.
