How to Grow Arugula: A Comprehensive Guide
Planting
Arugula is an annual leafy vegetable that can be grown in the garden or in containers. It prefers full sun or part shade and well-draining soil. The seeds should be planted about 1/4 inch deep and an inch apart in rows that are about a foot apart. Arugula can be planted in the early spring or late summer, and it will be ready to harvest in about 40 days.
Care
Arugula requires regular watering, especially during hot weather. The soil should be kept moist but not soggy. Arugula also benefits from fertilizing with a nitrogen-rich fertilizer.
Growing in Pots
Arugula can be easily grown in containers, which makes it a great option for those with limited space. Choose a container that is at least 6 inches deep and has drainage holes. Use a well-draining potting mix and water regularly.
Harvesting
Arugula is ready to harvest when the leaves are about 3 inches long. The leaves can be harvested by cutting or tearing them off at the base of the plant. Arugula can be harvested multiple times throughout the growing season.
