Chitting potatotes - a problem?
A few weeks ago I put seed potatoes in my cold frame outside to chit.
Unfortunately, it was too early and the frost got them so I brought
them indoors where they continued to grow green sprouts. However the
green sprouts have now turned purple and look sort of mould-like and
nasty rather than green and healthy. Should I discard them or are
they still worth planting?
