I don't know what the hell the previous occupants were doing here but it seemed to include a breeding programme for crustaceans.
Slugs, hmm. Catch and destroy. Hours of fun.
The worst bean critter we had was a neighbouring rooster who we saw finishing off the last beans of two rows just when the beans were swollen and sprouting. A jab into the ground with his beak, up came a bean like a plum from a pie, gobble gobble, no more beans. Aarrgghh!
