Well I've screwed up my cucumbers and courgettes. I planted the seeds in one of those seed snails, putting a marker between the two different types of seeds. But when I unwrapped them, I forgot which side was which and couldn't tell by the seedlings so made a best guess. I now can see that I was wrong. So each plant is in a completely in appropriate place and the courgettes definitely can't stay where they are, but it "might" be possible to construct a climbing frame for the cucumbers where they are (however awkward). If I dig them up and try to replant them are any of them likely to survive? I've about 6 of each plant. 😢
