Planting Arugula Lettuce Seeds

Arugula lettuce is grown from seed. Directly sow seeds in your vegetable garden early in the season. Then, cover seeds lightly with 1/8″ or less of fine garden or seed starting soil. Seeds will sprout in 3-10 days. Seeds sprout in cool soil at 40 to 55 degrees.

After seedlings have sprouted, thin to two inches apart, in rows 12″ – 18″ apart. Also, you can broadcast the seeds and grow the plants in an area rather than a row. However, you still need to thin the plants, for maximum growth.

Succession planting will result in continuous greens. Sow small rows of seeds every two weeks.
