The Director finds this difficult as she is trying to be organic and ecologically friendly.
Rabbits
I like rabbits, the Director only likes them the other side of allotment fencing, Mr Stanford only likes them in a stewing pot. Appleton Allotments are fenced in with wire that goes a good two feet underground so the rabbits can't dig underneath. One still got in though; he soared over the low slung wooden gate and ate all of Duffus's lettuce, some of our alfalfa and three of Mr Stanford's carrots. The Director was very cross and Duffus put netting over the gate. Mr Stanford said at least the rabbit had good taste.
Slugs
These are a problem if you're not using slug pellets and you don't have a hedgehog. We have one; he lives in the hedges but he can't get through the rabbit proof fence. The Director has tried a number of approaches:
- Garlic pellets - stopped only the tiny white slugs
- Egg shells - didn't work
- Gravel - didn't work
- Chanting - didn't work
- Morning and night patrols with torch and bucket - helped but very laborious and I have observed slugs are sly - they know how to hide.
- Copper mats - the big slugs were undeterred
- Copper rings - these worked - except when leaves hung over the ring and made a sort of ladder for the slugs. Mr Stanford was almost impressed until he heard how much the rings cost. He uses red slug pellets. Duffus uses blue slug pellets which are organic and don't harm rabbits or birds but the Director doesn't believe this would be any consolation to a slug.
This year she's going to try a pond and get a frog - a sort of middleman to eat the slugs. She also grows more seedlings in pots at home and plants out when they're big enough to stand a bit of munching; only some slugs have no restraint and last year all our cabbages went.
Mice
They like cabbages and all root vegetables and in a very cold winter will even eat Brussels sprouts. Last year they did for our sweet-corn. 
My dress flapped really hard but they didn't take any notice of me; perhaps they're related to Gary. This year the Director told Mr Stanford she is going to create a barrier with flowerpots so the mice can't reach the cobs. Neither Mr Stanford nor I understood what she meant so we're waiting to see.
Mr Stanford doesn't have a mice problem - he uses mouse traps.
Duffus also uses them amongst his vegetables but doesn't tell the Director.
Mabel doesn't seem to have a problem with mice; I don't know why.
