Er, do they rub off?
Well, you always peel off the first skin??
The problem I have is that there are small black spots on the Brussels, these outer leaves just peel off before cooking so they are not too much of a problem, but does anyone know what causes this, is it an indication of pests or something to do with the soil?
Thanks
Paul
I noticed the leaves at the tops of my sprout plants had gone black today, although the sprouts themselves were fine. Wondered if it was that bit of frost we had?
