How to Grow Arugula in North Carolina

Arugula, also known as rocket or roquette, is a popular leafy green that adds a peppery flavor to salads and dishes. Growing arugula in North Carolina can be a rewarding experience, thanks to the state’s diverse climates and growing seasons. This article will guide you through every step of cultivating arugula, from selecting the right varieties to harvesting your crop.

Understanding Arugula

Arugula belongs to the brassica family, which includes other greens like mustard and kale. It is known for its rapid growth and ability to thrive in cooler temperatures. The leaves are rich in vitamins A, C, and K, making them a nutritious addition to your diet.

Varieties of Arugula

When growing arugula, you can choose between several varieties:

1. Wild Arugula: This variety has a more intense flavor and is often used in gourmet dishes.
2. Cultivated Arugula: Milder in taste, this is the common type found in grocery stores.
3. Mature vs. Baby Leaf: You can grow arugula for mature leaves or baby leaves, which are harvested earlier for a tender taste.

Optimal Growing Conditions

Climate Considerations

North Carolina experiences a wide range of climates, from humid subtropical in the east to temperate in the west. Arugula prefers cooler temperatures of 45°F to 65°F. In North Carolina, you can generally grow arugula in the spring and fall.

• Spring Planting: Start seeds indoors in late winter (around February) or sow them directly outdoors in early March.
• Fall Planting: Sow seeds directly outdoors from late August through early September.

Soil Requirements

Arugula thrives best in well-drained soil rich in organic matter. Here’s how to prepare your soil:

1. Soil pH: Aim for a pH between 6.0 and 7.0. You can use a soil test kit available at local gardening centers.
2. Soil Preparation: Amend your soil with compost or well-rotted manure to improve drainage and fertility.
3. Tillage: Loosen the top few inches of soil with a garden fork or tiller to promote root growth.

Sunlight Needs

Arugula prefers full sun but can also tolerate partial shade, especially during the hottest summer months. Ideally, select a location that receives at least 4-6 hours of direct sunlight daily.

Planting Arugula

Seed Selection

Choose high-quality seeds from reputable suppliers. Look for varieties suited for your local climate conditions.

Sowing Seeds

1. Direct Sowing: You can plant arugula directly into prepared soil by sowing seeds about ¼ inch deep and spaced 1 inch apart.
2. Row Spacing: Space rows about 12 inches apart to allow for airflow and easy access during maintenance.

Transplanting Seedlings

If you started seeds indoors, transplant seedlings when they are about 4-6 weeks old:

1. Hardening Off: Gradually acclimate seedlings to outdoor conditions over a week by exposing them to sunlight and wind.
2. Transplanting: Dig holes about as deep as the root ball of your seedlings and space them 6-12 inches apart in rows.

Care and Maintenance

Watering

Proper watering is crucial for healthy arugula growth:

• Frequency: Water regularly, keeping the soil consistently moist but not soggy.
• Method: Use drip irrigation or water at the base of plants to avoid fungal diseases that can develop with overhead watering.

Fertilization

While arugula doesn’t require heavy fertilization, you may want to apply an organic fertilizer high in nitrogen (like fish emulsion) every few weeks to support leafy growth.

Weed Control

Weeds compete for nutrients and water:

• Mulching: Apply organic mulch around plants to suppress weeds.
• Hand Weeding: Regularly check your garden for weeds and remove them by hand when they first appear.

Pest Management

Arugula is susceptible to pests such as aphids, flea beetles, and cabbage worms:

• Monitoring: Inspect your plants frequently for signs of infestation.
• Organic Solutions: Use insecticidal soap or neem oil to manage pests organically without harming beneficial insects.

Harvesting Arugula

Timing Your Harvest

You can begin harvesting baby leaves as soon as they reach about 3 inches tall (approximately 3-4 weeks after sowing). For mature leaves, wait until they are fully developed (around 6 weeks).

Harvest Techniques

1. Cutting Leaves: Use scissors or garden shears to cut leaves just above the base of the plant; this encourages new growth.
2. Avoid Over-Harvesting: Never harvest more than one-third of the plant at one time to allow it to continue growing.

Troubleshooting Common Problems

Even experienced gardeners face challenges when growing arugula:

Bolting

As temperatures rise, arugula may bolt (go to seed), leading to bitter-tasting leaves:

• Solution: Plant arugula early in spring or later in fall for cooler weather growth.

Disease Issues

Watch for fungal diseases such as downy mildew:

• Solution: Ensure good airflow between plants and avoid overhead watering to minimize moisture on leaves.

Storing and Using Arugula

After harvesting your arugula, proper storage is essential:

• Refrigeration: Store unwashed arugula in a plastic bag or container in the refrigerator crisper drawer where it will stay fresh for up to a week.
• Culinary Uses: Use fresh arugula in salads, sandwiches, pizzas, pestos, or sautéed dishes.

Conclusion

Growing arugula in North Carolina is not only feasible but also enjoyable due to its fast-growing nature and culinary versatility. By following these guidelines on climate considerations, soil preparation, care techniques, pest management, and harvesting strategies, you can enjoy a bountiful crop of deliciously peppery greens throughout multiple seasons of the year! Whether you’re an amateur gardener or seasoned pro, adding arugula to your home garden will enhance both your meals and gardening experience. Happy planting!
