Black poly pipe about 1" or better diameter and put regular bird netting
over it, with PVC pipe about 1.25 - 1.5 " along the ground on both sides
with the bird netting wrapped around it. When you want to remove the netting
just pick up one pvc and lay it across on the other side which will pull the
netting back. If your beds are very long, you may have to do the net in two
segments.

IT won't keep out the coons though
