I have been given some Red Cross onion sets. I have some onions planted now and don't really want to plant more this autumn. I have read that I can keep them in a mesh bag, possibly in an attic. My question is, will they be ok in the dark? Also, the attic gets quite cold in the winter. Many thanks for any advice you can give me. Lynne.
