Whahey!!!....my sharp-eyed sister-in-law has worked out what I was growing from seed in the fish-box, which has been turned into my cold-frame - see here http://myword1.blogspot.co.uk/2013/06/bounty-from-kailyard-and-harvest-from.html There were faded letters on the white plastic name sticks which I had not noticed. I now know for certain I have radishes, there's more lettuce, over and above that which I planted outside the cold-frame. The thin green spindly things that sprouted out in a loop, then straightened up, (after a fashion) have been put out to grow as I think they are spring onions. S-I-L agrees with me about them. That leaves me with at least four cucumber plants not yet ready to pot on. When they are, they will live under the polythene cover of the frame.
However, not all is resolved; I pricked out some slim pointed leaves into larger pots to give them more space to develop. I have absolutely no idea what they will become. Back to the drawing board then - check in the box in which the packets of seeds were and with any luck, (fingers crossed) I might find a part packet of seed with a name on it. I cannot remember if I decided to try growing the beetroot. If I did, they should be yellow ones.
