I did as said on here and they are currently stored on racks in my shed. I'm thinking of putting them in plastic seed trays filled with compost and separated by dividers made from cut-off bits of plastic milk bottles as I don't know how many will be viable. I have a mini-greenhouse with a plastic cover that I used in my greenhouse last year where I plan to put them. Does this sound a good idea and when would be the best time to do this?
