Last year, I had some spare parsley plants after filling up their allotted space in the veg plot. I planted the spares in a couple of old plastic troughs that were lying around. I put the troughs on an old wooden ex-picnic bench, about three feet above the ground. Rabbits ate every single plant to the ground in the veg plot, but I got a magnificent crop from the troughs. All my plants will be off the ground this year.
