How to Grow Arugula in Vermont

Arugula, known scientifically as Eruca sativa, is a leafy green that has gained popularity for its peppery flavor and versatility in salads, sandwiches, and various dishes. It is a cool-season crop, making it particularly well-suited for the climate of Vermont, where the growing season can be short but is highly conducive to cultivating this delicious green. Whether you’re a seasoned gardener or just starting, this guide will help you grow arugula successfully in Vermont.

Understanding Arugula

Before diving into the nitty-gritty of growing arugula, it’s important to understand what this plant requires:

• Soil Type: Arugula thrives in well-drained, fertile soil rich in organic matter. A pH level between 6.0 and 7.0 is ideal for optimal growth.
• Sunlight: While arugula can tolerate partial shade, it performs best in full sun.
• Temperature: This crop prefers cooler temperatures and can be sown as early as four weeks before the last frost in spring. In Vermont, the ideal growing temperatures range from 45°F to 75°F.

Choosing the Right Variety

There are several varieties of arugula available for cultivation, including:

1. Wild Arugula (Diplotaxis tenuifolia): This variety has a more intense flavor and is often used in gourmet dishes.
2. Cultivated Arugula: The most common variety found in gardens, it has broader leaves and a milder flavor.
3. Rocket: This term is often used interchangeably with arugula and generally refers to any species within the Brassicaceae family that has a similar peppery taste.

For Vermont growers, cultivated arugula is usually the best option due to its adaptability and flavor profile.

Preparing Your Garden Bed

Site Selection

Choose a location that receives full sun for at least six hours a day. If your garden area has heavy clay or poor drainage, consider raised beds to improve soil conditions.

Soil Preparation

1. Test Your Soil: Before planting, consider testing your soil to determine pH and nutrient levels. Local agricultural extension offices often provide soil testing services.

2. Amend the Soil: Based on test results, you may need to amend your soil with compost or well-rotted manure to improve fertility and drainage.

3. Tilling: Loosen your soil by tilling it to a depth of about 12 inches. This will help aerate the soil and facilitate root growth.

4. Leveling: Rake the garden bed to create a smooth surface for planting.

Sowing Seeds

When to Plant

In Vermont, you can sow arugula seeds outdoors in early spring (April) or late summer (August). This is crucial for ensuring you avoid the heat of summer, which can cause the plants to bolt (flower) prematurely.

Planting Method

1. Direct Sowing: Sow seeds directly into the garden bed by creating shallow furrows about ¼ inch deep.

2. Seed Spacing: Space seeds about 1 inch apart or scatter them evenly across the bed if you prefer a dense planting.

3. Covering Seeds: Lightly cover the seeds with soil and water gently to ensure good seed-to-soil contact.

4. Thinning Seedlings: Once seedlings reach about 2-3 inches tall, thin them out so that they are spaced approximately 6 inches apart. This ensures adequate air circulation and reduces competition for resources.

Watering Practices

Arugula requires consistent moisture for optimal growth:

• Watering Frequency: In general, aim to provide around 1 inch of water per week through rainfall or manual watering.
• Soil Moisture Check: Insert your finger into the soil; if it feels dry up to your first knuckle, it’s time to water.
• Avoid Overwatering: While consistent moisture is key, avoid soggy soil conditions that can lead to rot or disease.

Pest Management

While arugula is relatively pest-resistant, some common pests include:

• Aphids
• Flea Beetles
• Cabbage Worms

Organic Pest Control Methods

1. Companion Planting: Grow herbs like basil or marigolds nearby to deter pests naturally.

2. Neem Oil: Use neem oil sprays as an organic pesticide if necessary.

3. Row Covers: Employ floating row covers early in the season to protect young seedlings from pests.

Fertilization

Arugula does not require heavy fertilization but benefits from a balanced fertilizer applied at planting time:

• Organic Options: Use compost or organic fertilizers like fish emulsion or seaweed extract.
• Timing: Apply additional fertilizer when you notice rapid growth or if leaves appear pale green.

Harvesting Your Arugula

Arugula leaves can be harvested as soon as they are large enough to eat—usually around 4–6 weeks after sowing:

1. Cutting Leaves: Use scissors or garden shears to cut leaves from the base of the plant rather than pulling them out entirely; this encourages new growth.
2. Timing for Best Flavor: Harvest early in the morning when temperatures are cooler for the best flavor and crispness.
3. Continuous Harvesting: Regularly harvest leaves throughout the growing season to encourage continuous growth.

Potential Challenges

Bolting

Bolting occurs when plants flower prematurely due to stress factors such as heat or drought:

• To prevent bolting, keep your arugula consistently watered and provide shade if temperatures climb too high.

Diseases

Leaf spot diseases can affect arugula under humid conditions:

• Improve air circulation through spacing and avoid overhead watering during late afternoons.

Conclusion

Growing arugula in Vermont can be a rewarding experience that enhances both your garden and kitchen table. With its quick growth cycle and delectable flavor, arugula offers an excellent opportunity for both novice and experienced gardeners alike. By following these steps—from site selection and soil preparation to pest management and harvesting—you can enjoy bountiful yields of this nutritious leafy green throughout your growing season.

As you cultivate arugula, remember that gardening is not just about growing food; it’s also about enjoying nature’s beauty and participating in sustainable practices that benefit both you and the environment. Happy gardening!
