Last spring (a year ago) I planted several hundred dollars worth of new ground covers and other plantings across my railroad. Within days, the birds, rabbits, and squirrels started digging them up. So this year when I plant the replacement plants (in a few weeks), I need to find a way to scare the critters away. I'm wondering about scare-crows, plastic owls, metalic ribbon, pin-wheels, etc. Does anyone have any good ideas that have worked for them? If so, please advise. I really want to protect my plants this year.
