How to Grow Arugula in Maryland

Arugula, also known as rocket or roquette, is a leafy green vegetable that belongs to the Brassicaceae family. Known for its peppery flavor, arugula is a popular addition to salads, sandwiches, and pizzas. Growing arugula in Maryland can be a rewarding experience, thanks to the state’s temperate climate which is suitable for this fast-growing leafy green. This article will guide you through the process of growing arugula successfully in Maryland.

Understanding Arugula

Arugula (Eruca sativa) thrives in cooler temperatures and can be grown in both spring and fall. This fast-growing crop can go from seed to harvest in about 30 days, making it an excellent choice for gardeners looking for quick results. Arugula is also a cool-season crop that can tolerate light frost, making it versatile for different growing seasons.

Choosing the Right Variety

When selecting arugula seeds, consider the various varieties available. Some popular options include:

Wild Arugula: This type has a more intense flavor and is often used in gourmet dishes.
Astro: A hybrid variety known for its smooth leaves and mild taste.
Rocket: A traditional variety that offers robust flavor but can become quite spicy if left too long before harvesting.

Each of these varieties has unique characteristics that may suit your taste and garden conditions. It’s best to choose a variety that matches your culinary preferences and local growing conditions.

When to Plant Arugula in Maryland

Maryland’s climate presents an ideal environment for two main planting seasons for arugula:

Spring Planting

Timing: Aim to plant arugula seeds in early spring, ideally between mid-March and early April. This allows the plants to mature before the heat of summer.
Soil Temperature: The optimal soil temperature for germination is around 40°F to 60°F.

Fall Planting

Timing: For a fall crop, plant seeds from late August through early September. This allows the plants to grow into the cooler months.
Frost Consideration: Since arugula can tolerate light frost, it’s usually safe to continue growing until late October or even November with proper care.

Soil Preparation

Healthy soil is key to successful arugula growth. Here are steps to prepare your garden bed:

Choose the Right Location: Select a spot that receives full sun (at least 6 hours of sunlight) but can also tolerate some shade during the hottest part of the day.
Soil Testing: Conduct a soil test to determine pH and nutrient levels. Arugula prefers a slightly acidic to neutral pH range (6.0-7.0).
Amendments: Incorporate organic matter such as compost or well-rotted manure into the soil to improve fertility and drainage.
Tilling: Till the soil to a depth of at least 12 inches, breaking up clumps and removing weeds or debris.

Planting Arugula Seeds

Once your soil is prepared, it’s time to plant:

Seed Spacing: Sow seeds about ½ inch deep and space them 1 inch apart in rows that are 12-18 inches apart.
Watering: Water gently after planting to moisten the soil without displacing the seeds.
Thinning Seedlings: Once seedlings have emerged (typically within 5-10 days), thin them by snipping off weaker plants near the base, allowing stronger plants enough space (6-8 inches apart) to grow.

Caring for Your Arugula Plants

Proper care will ensure a healthy harvest:

Watering

Consistency: Keep the soil consistently moist but not soggy. Overwatering can lead to root rot while underwatering can stress plants.
Method: Water early in the morning or late in the afternoon to minimize evaporation.

Fertilization

Utilize a balanced fertilizer once plants are established if necessary, especially if your soil test indicates low nutrient levels.
Organic options such as fish emulsion or seaweed extract can provide necessary nutrients without chemical additives.

Pest Management

While arugula is generally resilient, it’s susceptible to pests such as aphids and flea beetles:

Barrier Methods: Use row covers during early growth stages to protect seedlings.
Natural Remedies: Introduce beneficial insects like ladybugs or use neem oil spray as needed.

Weeding

Regularly check for weeds around your arugula plants since they compete for nutrients and water:

Hand-pulling weeds is effective; be careful not to disturb arugula’s shallow roots.

Harvesting Arugula

Arugula can be harvested multiple times throughout its growing cycle:

Baby Leaves: For tender baby leaves, harvest when they are about 2-3 inches tall; this usually occurs around 3 weeks after planting.
Mature Leaves: For larger leaves, wait until they reach about 6 inches tall; this will give them time to develop stronger flavors.
Cutting Method: Use scissors or sharp shears to cut leaves just above ground level; this encourages further growth rather than pulling up whole plants.
Timing Considerations: Harvest in the morning when leaves are crisp with moisture for optimal flavor and texture.

Dealing with Bolting

As temperatures rise or if plants are stressed, arugula may bolt (flower and go to seed). Bolting results in bitter leaves:

If you notice bolting starting, harvest any remaining leaves immediately.
To avoid bolting, ensure consistent watering and try planting heat-tolerant varieties during warmer months.

Storing and Using Your Harvested Arugula

Freshly harvested arugula tastes best when consumed immediately but can also be stored:

Storage Tips: Place unwashed arugula in a damp paper towel inside an airtight container or plastic bag in the refrigerator – it can last up to a week.
Culinary Uses: Arugula can be enjoyed fresh in salads, mixed into pestos, added as a topping on pizzas, or used as a garnish for various dishes due to its unique flavor profile.

Conclusion

Growing arugula in Maryland is an easy and fulfilling gardening endeavor that offers delicious rewards within weeks of planting. With attentive care from preparation through harvest, you can enjoy fresh arugula throughout much of the year—making it a great addition to your home garden. Whether you’re an experienced gardener or just starting out, incorporating arugula into your plot will enhance your culinary creations while providing nutritious greens right from your backyard!
