I don't know the answer about your plumbago, but I can give you a good answer for the squirrel issue.

Can you say, 'gumbo?' I knew you could. Worked for me, and the squirrels finally served a good purpose. Or rather were served at a good dinner.

That said, my issues involved squirrels chewing their way into my house and eating insulation and wiring. They are WAY destructive.

I'm all for that! Our yard is OVERRUN with squirrels. We have a peach tree, fully loaded this spring, now nothing. We have an Asian pear with pears, they're disappearing and probably gone as we speak. We have a pecan tree... never mind getting nuts off of it. I think pellet guns are illegal in the city though. Any other thoughts?
