Here on the 'Growing Plot.' we have a few bunnies, chances are by next
year they would have multiplyed, so we need to stop them eating our
vegetables, how high and how deep does our fence need to be,
Bearing in mind we are a charity helping vunderble young adults, whats
a cheap way of keeping the bunnies out.

Get a cat! There are times in the year (when they are breeding) when
I hardly need to feed one of mine he's so good at catching rabbits.

On a different track I had a pet rabbit as a child. One night he dug
his way out of his run and decimated the lettuce I had been growing.
He didn't stay long after that! The point is, you need to bury the
fence into the soil as well as having it above the soil.
