I hope!
Each year the problem with badgers on our site gets worse. The past few years they have trashed everyone's sweetcorn despite the best efforts of netting to keep them out.
This year I've built the construction below in an attempt to deter them. The poles and grills I fortunately had to hand, so only paid for the mesh. I intend burying the grills that are currently laying on the soil below the surface.
Cost was about £40, but this is protecting about 100 plants and everything is reusable year on year, so ultimately hopefully the unit cost per cob will be low. If they get through this - it's more peas next year!
