Arugula is a cool-season plant and will grow at temperatures as low as 40 degrees F. Scatter seeds 1/2 inch apart and cover lightly with soil. In late summer, refrigerate seeds for a week in a small bag with a sprinkling of potting soil and plant in the evening. Keep the dirt moist to prevent plants from flowering, which makes them taste bitter. Leave about 3/4 inch on the stem when you trim leaves.
