For optimum flavor, grow in cool weather. Sow in average soil in a sunny to partially shady area as soon as the ground can be worked. In rows 15 inches apart, sow seeds evenly and cover with ¼ inch of fine soil. Firm and water gently. Seedings emerge in 7-14 days depending on soil and weather conditions. Arugula also grows well in containers. Use a commercial potting mix rather than garden soil. Thin gradually to stand 6 inches apart starting when seedings are about 3 inches high. Sow again in late summer in a protected area when the temperature is below 75°F.
Tender young leaves have a robust flavor, they should be ready to use about 30-35 days after sowing.
To harvest, pick off the outside leaves at the base of the plant. Leave center intact for future harvesting.
Younger leaves, 2-3 inches long, taste best.
You can also harvest whole plants by cutting off just below the crown.
Stop picking once plants flower as the leaves will become bitter-tasting. Flowers are also edible.
