Don't worry, Meterman, you're not alone - last year we had seventy-two, and this year there will be about ninety...
I really work on the principle that if we get blight, that at least a few may escape, and therefore we get a crop, however depleted! Also, we're growing more down on the allotment because the soil is much improved now, and I think that they just might like getting their paws into loads of muck, as opposed to the pots of compost we use at home, in the greenhouse!
