A hardy and easy green to grow. Start inside and use as a mircogreen or direct sow out in the garden mid-late spring. Arugula can bolt (go to seed) quickly in the heat of the summer so pick often. Arugula is ready for harvest just 35 days after seeding. Add the pungent, peppery leaves to spicy salads, harvesting them when they reach 10-15cm (18-24")
