Black Vine Weevil - Grrrrrrrrrrrrrrrrrrrr
About four years ago, I discovered that the dreaded weevil had made a home in our azaleas. I have tried every organic remedy that I could find, by appropriate season. I knew that I had not eradicated them, but I seem to have slowed the spread.
We have lost one azalea, and two more seem to be getting smaller every year. I now find that they have spread in the opposite direction and made a home with the new Otto Luyken.
I am ready to bring in the big guns...chemicals!
Can anyone who has had success with chemicals, please offer me some advice? Which chemicals/which brands? If I irradiate them in one area, will they simple spread to another? How much of an area do I need to treat? Is there any value to using Grub Ex (imidaclropld) in the bed or surrounding lawn?
This is absolutely breaking my heart. I would be so grateful for some wisdom.
