All your seedlings for starters. Lettuce, spring cabbage and caulis such as Aalsmeer for Aug transplanting and a May harvest. Marathon Calabrese can be sown now for planting out in August for harvest Oct-Nov. Aug-Nov sow Valdor winter lettuce. It harvests from Nov-April. Late sowings should remain under glass throughout winter. I sow my radish and spring onions in margerine tubs or 5" pots in the greenhouse too.
