Scott,

2 inches, or a little more. I don't think I've ever gone more than three inches.

SVB mostly like to start their attack near ground level, if I can believe what I've read.

It's the reflective nature of the aluminum foil that is supposed to repel them more than the physical barrier, again from what I've read.

The one thing I do know, I've had no SVB in mostly sunny growing seasons, and have had SVB in very cloudy growing seasons, while using the aluminum foil method.
