I planted some speedy salad leaves in small pots with the intention of transplanting into larger containers. Is this necessary, or can I leave them in the small pots? Also, do you think they need thinning out? Thanks.
I agree they will need to be moved. I grow a lot of lettuce in boxes 6inchesx6inchesxeight feet long. By the end of the year the box holds a solid hunk of roots but the roots have done their job by then.
