We can never seem to have enough onions even though we plant more every year. This year I hope to reach the goal of some form of onions in the box every week of the year. We are planting many different kinds including shallots. They are all seeded into trays and planted into the field as soon as we can pull the plant  out of the tray. We sow about four or five seeds in each cell. We are now waiting on more plastic trays from our supplier so that we can complete the planting.
