Germination rates differ from locality and prevailing weather conditions. Rutabaga, lettuce and spinach I count on 50% germination. Some year more, a few years less. Rutabaga and romaine need a bit more space than spinach. I plant all of of the by sowing thin in multiple rows In other words I create a bed of 2-6 rows 6 inches apart. The bed itself is a row separated 2-3 ft. from adjoining rows. I sow the seeds anticipating a seed every inch. but I don't do any measurements just sprinkle the along the row. Rutabaga I double the distance between rows and between seed.
