DD planted some radishes (french breakfast) last week in a tray some of that growing salad came in (with fresh compost of course) they have come up lovely 
Am a bit concerned now, that I haven't thought it through, I'm thinking it might not be deep enough. Can I lift them out in one go and just put them in a deeper tray?
Also do I need to thin them out, they are currently about 2-3 cm.
God I'm rubbish at this sort of stuff
