This is how I always grow my leeks MMM and they end up about 3 inches in diameter .. one leek is more than enough veg in a meal for two of us.Millymollymandy wrote:not sure why anyone would grow them in seed trays???
But you are right about the roots.
I sow mine indoors because they just don't germinate and grow fast enough if I sow them outside, one of the downsides of living here.
I sow them in seed trays and then prick them off into 8 inch pots, about a dozen to a pot, that gives them plenty of room for their roots and gets them off to a nice early start. I don't sow them until around the middle of March though, any sooner and you run the risk of them bolting before winter comes.
