Arugula, also known as rocket, is a popular salad green. It has a peppery flavor, similar to mustard greens, that gets hotter as the plant matures. When used properly, the boldness of arugula perfectly balances out the delicate flavors of other greens that are used in salads, such as lettuce or spinach. Arugula can sometimes be difficult to find and overpriced in stores, so growing it at home is a better option.
Prepare a sunny spot to plant the seeds in mid-spring once the soil has warmed up from the winter. Mix the soil to a depth of at least 3 inches with a hoe to add oxygen and promote drainage.
Remove the remains of any weeds, as the roots may grow into new plants.
Plant the seeds 1/4 inch deep in the soil. Space the seeds at least 3 inches apart to ensure the plants have plenty of room to grow.
Water the soil so it is moist to the touch. The soil should remain moist at all times as arugula isn't tolerant of droughts.
Harvest the leaves once they reach 3 inches in length. Each plant will continue to grow new leaves after the original leaves are harvested.
