I dug out some tiny seedlings from the cracks in my patio and they have grown on really well, They are now between 4" & 6" high & in 3" pots.
Trouble is I am not sure what to do next - do I plant them out in the autumn or leave them to overwinter in a cold frame? If I do leave them in a cold frame, should I pot them on into bigger pots or leave them as they are?
Advice much appreciated
