It was nearly May when I got into the garden to transplant AND direct-seed cool crops. In the meantime, I got my warm weather transplants started. So the order of the seed packets was irrelevant. Before I do any sowing, I make a planting schedule. On calendars in the potting area, at my desk, and in the kitchen, so I can see it every day, I mark the approximate dates to sow the seeds.
Some folks make a big planting chart for the wall to see the season at a glance.
Others write a schedule in a notebook, journal, or on the computer. At the end of the season, all the seeds are back together in chronological order. Then they are easy to inventory and reorder come January. The Guy Code Gothic.
