Sweetcorn. Year 1 - rained off, year 2 - stunted and cobs not formed, year 3, wonderful cobs, due for picking later that week. Squirrels or rats got THE WHOLE LOT. That's right, each cob, leaves, silk and all. Each succulent tiny little yellow grain .....gone. I am as devasted as my sweetcorn, and I will never grow them again.
