​Also known as “rocket” or “roquette,” arugula is a fast-growing, cool-season salad green that adds a tangy, mustard-like flavor to salads. Here’s how to plant and grow arugula in your garden.

Arugula is often found in mesclun mixes. Plant early or late in the growing season and you will be able to harvest as soon as 4 weeks after sowing. The seedlings are hardy and tolerate some frost.

Planting

Arugula prefers humus-rich, well-drained soil, but will tolerate a wide variety of conditions.
Plant outdoors in full sun or part shade as soon as the soil can be worked in spring. See local frost dates.
Sow in late-summer for a fall or early-winter harvest.
Plant ¼-inch deep and about 1 inch apart in rows 10 inches apart. Alternatively, broadcast arugula seeds alone or mix with other greens.
Seeds germinate in a few days.
Sow new seeds every 2 to 3 weeks for a continuous harvest.

Care

Keep soil evenly moist.
Thin seedlings to about 6 inches apart, using the thinnings for salads.
To reduce heat stress, provide some shade for warm-season plantings.

Pests/Diseases

Flea beetles
Cabbage worms
Downy mildew

Harvest/Storage

The leaves taste best when young.
Harvest leaves when they are about 2-3 inches long.
Pull up the whole plants or cut individual leaves.
The white flowers are edible.
