I sowed my maincrop potatoes in one of the raised beds on 30th March, varieties were Mozart, Maris Piper and King Edward. All the seeds were chitted and planted using exactly the same method, however, the Maris Piper & Mozart have totally failed to grow, I mean not even broken the surface! The King Edward were my own saved seeds from last year and they are absolutely thriving, unfortunately, after digging a few of the others out, the chits are the same size as when they were planted. The MP & M were bought from the supermarket, but saying that, I bought MP from the same supermarket last year and they grew ok?

I wouldn't prune it to below first leaves right after flowering - I'd do it in stages, remove a couple of feet then, and then the rest once it has lost all its leaves in winter

Sunny but not hot, so a very pleasant day for sitting out or just musing around the garden.

MB, that's what I used to do but the module tray is so flimsy that if I get my hand underneath and squeeze the whole lot might fall out! 

That's a great idea!
