Thank you Folks!
With your advice, I think the space will endure an annual crop now - the soil is perfect for such an abundant row, (it's an old compost heap - slightly re-organised), and a speedy growth normally means a tender result! (Well, that's what Mrs Growster always tells me...:0)
As I have a spare cubic inch in the freezer, I may well try some there as well, but as I'm off to Twongos tomorrow, don't bet on it...!
