Deer deterrent back up choices

Any system that helps to deter deer could use a back up.

One such method I've been thinking of lately is a field of marigold flowers also known as Calendula Officinalis.

California poppies, bleeding hearts, calla lilies, and corn poppies all have been reported to help keep deer out of your garden.

It should be noted that just because a deer doesn't like something doesn't mean he or she will never partake of its forbidden flavor. Deer do seem to shy away from marigold flower smells, but if times are desperate they just might nibble on whatever they can get. It's these times that require some mechanical help in the form of a noise and motion contraption.
