I live in a city, but love sweet corn so I grow a little in my garden.
Unfortunately, raccoons have discovered my corn and are eating it before it is ripe. The city frowns on killing them, and trapping doesn't work because you just get one at a time and they find their way back after being released.
So I am looking at building a fenced area, with wire fencing on the sides, and netting on the top. I found what seems to be an affordable welded wire fence material, but the openings are 2 by 4 inches. Is that small enough to stop raccoons, or do I need to find a material with smaller holes?
