The arugula plant grows best in well drained soil, but it likes a lot of moisture so water frequently. The plants also prefer a soil pH of 6-6.5. Dig in some well rotted manure or compost before sowing to satisfy both these needs. This should be done as soon as the soil can be worked in the springl or better yet, prepare the soil in the fall before you shut down your beds so they’ll be ready to plant for spring growing. Arugula loves cool weather and in most parts of the United States can be planted as early as April. All you need are daytime temperatures above 40 F. (4 C.).



Even frost won’t hold it back. Argula grows best in a sunny location although it tolerates some shade, particularly when summer temperatures rise. To satisfy that itch we gardeners get each spring to harvest something we have planted, there’s nothing like growing arugula.

Plant the seeds about a ¼ inch deep and 1 inch apart, then gradually thin to 6-inch spacing. Don’t throw those seedlings away.



They’ll make a tasty addition to your salad or sandwich. Once the remaining plants have several sets of leaves, you can begin harvesting. Don’t pull the entire plant, but take a few leaves from each so you’ll have a continuous supply. Another advantage to growing arugula from seed is that you can make new plantings every two to three weeks to keep the supply going all summer.

Don’t plant too much at one time because you don’t want the plants to bolt before you get a chance to harvest. For gardeners who are short on space, try growing arugula in a container. Any size pot will do, but remember, the smaller the pot, the more watering. For those of you with container grown trees, plant your arugula as a tasty and attractive soil cover. The roots are shallow and won’t interfere with the larger plant’s nutrients or growth. Now that you know how to grow arugula from seed, you’ll have to give it a try. You’ll be glad that you did.
