RABBITS

I surround mine with chicken wire, when they reach a good size, the rabbits leave them alone.
If you have a look at some of my pictures, you might just be able to spot the chicken wires around certain plants.

Wiring is the only answer but make sure it is in the ground a few inches or they will burrow under it.The other alternative is shoot the blighters !!!

Shoot them - 12 bore works wonders - then add black pudding and onions and cook slowly
