How to Grow Arugula

Arugula is a fast-growing leafy green that's easy to cultivate, making it a great choice for both novice and experienced gardeners. Here's how to successfully sow and grow arugula:
Sowing Arugula Seeds
Timing
Arugula is a cool-season crop, so it's best to sow the seeds in early spring or late summer for a fall harvest. The seeds can be sown as soon as the soil can be worked in spring, about 2 to 4 weeks before the last frost date. For a continuous harvest, consider sowing seeds every two to three weeks.
Location
Choose a sunny spot with well-drained soil. Arugula prefers full sun but can tolerate partial shade, especially in warmer climates. If planting in hot weather, a spot with some afternoon shade can help prevent the plants from bolting.
Soil Preparation
Arugula thrives in fertile, well-draining soil with a pH between 6.0 and 7.0. Before sowing, prepare the soil by adding compost or well-rotted manure to improve fertility and texture. Rake the soil smooth and remove any large clumps or debris.
Planting Depth and Spacing
Sow arugula seeds about 1/4 inch deep and cover them lightly with soil. Space the seeds about 1 inch apart in rows that are 10 to 12 inches apart. For a more natural look, you can broadcast the seeds over the soil and lightly rake them in.
Watering
After planting, water the soil gently but thoroughly. Keep the soil consistently moist but not waterlogged as the seeds germinate. Arugula seeds usually germinate within 5 to 7 days, depending on the soil temperature.
Succession Planting
To ensure a steady supply of arugula, practice succession planting every two to three weeks. This staggered planting ensures that as one batch is harvested, the next is ready to take its place.
Growing Arugula in Containers
If space is limited, arugula can easily be grown in containers. Choose a pot that's at least 6 inches deep with good drainage. Fill it with a high-quality potting mix, sow the seeds, and care for them as you would in the garden. Container-grown arugula may need more frequent watering, especially during hot weather.
By following these steps, you can enjoy a fresh, flavorful harvest of arugula throughout the growing season. Whether in the garden or in containers, arugula is a rewarding crop that adds a peppery punch to salads, sandwiches, and more.
How to Care for Arugula

Taking care of arugula is relatively simple, but a few key tips can ensure a robust and continuous harvest.
- Thinning Seedlings: Once the seedlings are about 2 inches tall, thin them to about 6 inches apart to give each plant room to grow. You can use the thinned seedlings in salads or as microgreens.
- Watering and Mulching:
Arugula has shallow roots, so it’s important to water regularly to keep the soil evenly moist. Mulching around the plants can help retain moisture, reduce weeds, and regulate soil temperature. - Sunlight:
Arugula grows best in full sun but can tolerate partial shade, especially in warmer climates. In regions with hot summers, providing some afternoon shade can prevent the plants from bolting too quickly. - Fertilization:
Arugula is a light feeder, but applying a balanced fertilizer or side-dressing with compost every few weeks can promote healthy, vigorous growth. Be cautious not to over-fertilize, as this can lead to overly lush growth with less flavor. - Pest Management:
Keep an eye out for common pests like flea beetles, aphids, and slugs. Regularly inspect your plants and use organic methods like row covers, insecticidal soap, or natural predators to control infestations. - Harvesting:
Arugula can be harvested as soon as the leaves are large enough to eat, typically when they’re 2 to 3 inches long. For a continuous harvest, pick the outer leaves first, allowing the inner leaves to keep growing. Alternatively, you can cut the entire plant at the base, and it will regrow for another harvest.
You can consider building a self-watering herb garden if you have busy schedules or travel frequently.
Advanced Companion Planting Strategies
For experienced gardeners looking to maximize their yields, advanced companion planting strategies can help:
- Intercropping
Pair arugula with slower-growing crops like carrots or beets. The fast-growing arugula can be harvested before the slower crops need the space, allowing for efficient use of garden beds. - Trap Cropping
Use arugula as a trap crop for pests like flea beetles. Plant arugula around the perimeter of your garden to attract pests away from more vulnerable plants like tomatoes or eggplants. Regularly inspect and remove any infested arugula plants to keep pests under control. - Polyculture Systems
Create a diverse garden ecosystem by planting arugula alongside a mix of herbs, flowers, and vegetables. This diversity can confuse pests, reduce the spread of diseases, and create a balanced environment that supports healthy plant growth.
Common Pest Problems and Solutions
While arugula is a hardy plant, it can attract some pests. Here are the most common ones and how to deal with them:
Flea Beetles
Flea beetles are small, black insects that leave tiny holes in arugula leaves, making them look like they've been peppered with buckshot. To manage these pests, cover young plants with row covers to prevent beetles from reaching them. Neem oil or insecticidal soap can also be applied if the infestation is severe.
Aphids
Aphids are tiny, soft-bodied insects that suck sap from arugula, causing leaves to curl and stunt growth. They can be managed by introducing natural predators like ladybugs or by spraying the plants with a strong stream of water to knock them off. In more severe cases, insecticidal soap can be used to control the population.
Cabbage Loopers
These green caterpillars can chew large holes in arugula leaves, severely damaging the crop. Hand-picking them off the plants is effective for small infestations. Bacillus thuringiensis (Bt), a natural bacterial pesticide, can be sprayed to target these pests without harming beneficial insects.
Slugs and Snails
Slugs and snails love to feast on tender arugula leaves, especially in moist conditions. You can protect your plants by using barriers like crushed eggshells or diatomaceous earth around the base of the plants. Slug traps or organic slug pellets can also be effective in reducing their numbers.
