The water butt rota
Four plots share two butts. A chalk board on the shed door with initials and dates settled more arguments than any committee meeting.
Slugs, beer traps and honesty
The beer traps catch slugs. They also catch the beetles that eat slugs, which nobody mentions. This year I went back to torchlight rounds at ten in the evening and a bucket, and lost fewer lettuces than with any trap.
Copper tape did nothing I could measure. Grit around the brassicas helped a little and looked tidy, which counts for something on a shared site.
Garlic in the autumn
Planted in late October, ignored all winter, lifted in July. It is the only crop on the plot that has never once disappointed me.
