Cheers, Duke. Almost out of boltardy, just 2 stragglers left in the ground, so "cutting" the white is not really much of an option. Thinking about it, I'd rather not "contaminate" my last couple of good beets. I've ordered golden for next year but I'll be sowing a lot more boltardy just in case.
I wonder if rabbits would eat it, I've got a mate with some. :(
