I sowed a 5 inch pot with a fairly thick spread of King Richard leeks today. Jack's compost used and a good spray on top. The compost was warm after a couple of days in the conservatory and so was the water. The pot is in a plastic crate "greenhouse" to keep it moist. (First seedlings up on Jan 28th)
The onions are well up now. About 3 cells with none, mostly 2 or three, some with more, may need to thin.
VERY hard frosts this last week.
