might also try laying fencing down on the ground around the beds. the
type of fencing that is wider "holes", green plastic covered fencing.
they dont like stepping on it because it "feels" like a leg trap.

consider an electric fence. By fence I mean a

wire about 1 foot above the ground. The second
wire is for racoons and groundhogs. Smear peanut
butter on the wires. Deer and other critters love
peanut butter. Once they get shocked a couple
times after licking, they stay clear.

This is used by several commercial vineyards near
me and they swear by it.
