If you love bold, zesty flavors in your salads or sandwiches, arugula (also known as rocket) deserves a spot in your garden. This leafy green, prized for its peppery bite and tender leaves, is a staple in Mediterranean cuisine and a rising favorite among American home gardeners.
Whether you sprinkle it over pizza, toss it in a fresh salad, or blend it into pesto, arugula adds a vibrant, gourmet touch to everyday meals. Best of all? It’s one of the easiest and fastest greens to grow — perfect for beginners or anyone who wants fresh produce in just a few weeks.
In this in-depth guide, we’ll explore everything you need to know about growing, harvesting, and enjoying arugula (rocket) — right from your backyard or balcony.
What Is Arugula (Rocket)?
Arugula (Eruca vesicaria) is a leafy green vegetable native to the Mediterranean region. It’s part of the Brassicaceae family, the same group that includes kale, broccoli, and mustard greens. In the U.S., it’s commonly called arugula, while in Europe and Australia, it’s often known as rocket or roquette.
Its flavor is what makes it stand out — a peppery, slightly nutty taste that adds instant character to salads, sandwiches, and pasta dishes. Because it grows quickly and thrives in cooler weather, it’s an ideal choice for spring and fall gardens across the United States.
Why Arugula Deserves a Spot in Your Garden
Arugula is more than just a trendy salad green. Here’s why American gardeners are falling in love with it:
- Fast-growing: Ready to harvest in just 3–4 weeks from planting.
- Low-maintenance: Perfect for beginners or small-space gardeners.
- Packed with nutrients: Loaded with vitamins A, C, and K, calcium, and antioxidants.
- Cold-tolerant: Grows well in spring and fall, even in cooler northern states.
- Endlessly versatile: Great for salads, pizzas, sandwiches, and pestos.
It’s a “grow it today, eat it tomorrow” kind of plant that fits perfectly into modern, fast-paced lifestyles — without compromising freshness or nutrition.
Best Varieties of Arugula to Grow
Not all arugula is the same! Different varieties offer unique leaf shapes, flavors, and growth habits. Here are some popular options for American gardens:
- Astro: Mild flavor and smooth leaves; grows quickly — great for early harvests.
- Rocket (Roquette): Classic variety with deeply lobed leaves and a sharp, spicy flavor.
- Sylvetta (Wild Arugula): Smaller leaves, slower-growing, but much more peppery and heat-tolerant.
- Wasabi Arugula: Offers a bold, wasabi-like kick — perfect for spice lovers.
- Olive Leaf Arugula: Elegant, elongated leaves with a subtle nutty flavor.
Mixing varieties in one bed gives you a continuous harvest of different textures and tastes.
When and Where to Plant Arugula
Arugula is a cool-season crop that thrives in mild temperatures — ideally between 45°F and 70°F.
- Spring planting: Start as soon as the soil can be worked, 2–4 weeks before your area’s last frost.
- Fall planting: Sow seeds 4–6 weeks before the first expected frost.
- Southern states: You can grow arugula through winter since it prefers cooler weather.
Choose a sunny or partially shaded spot in your garden. Too much heat or full summer sun can cause the plant to bolt (flower early), making the leaves bitter.
How to Plant Arugula (Step-by-Step)
Growing arugula from seed is incredibly easy — no green thumb required!
- Prepare the soil: Loosen the top 6 inches and enrich it with compost or organic matter.
- Sow the seeds: Scatter seeds thinly or plant them ¼ inch deep and 1 inch apart in rows about 10 inches apart.
- Water gently: Keep the soil moist but not soggy.
- Thin seedlings: Once plants are 2 inches tall, thin them to about 4–6 inches apart to allow room for growth.
Arugula germinates quickly — usually within 5–7 days — and grows fast, reaching harvest size in 20–30 days.
Care and Maintenance
Arugula is a simple plant that doesn’t ask for much but rewards you generously. Here’s how to keep it thriving:
- Water regularly: Consistent moisture keeps the leaves tender and prevents bitterness. Aim for 1 inch of water per week.
- Mulch around the plants: Helps retain moisture and regulate soil temperature.
- Fertilize lightly: If your soil is rich, it doesn’t need much feeding. A compost top-dressing mid-season is usually enough.
- Watch the heat: In warm climates, use shade cloth or grow in partial shade to prevent bolting.
With these basic steps, your arugula will stay lush, green, and flavorful.
Pests and Problems
Like most greens, arugula can attract a few garden pests — but they’re easy to manage.
- Flea beetles: Tiny holes in leaves? These little beetles are likely the cause. Use floating row covers or neem oil.
- Aphids: Wash them off with water or spray with insecticidal soap.
- Slugs and snails: Place crushed eggshells or copper tape around plants.
Avoid planting arugula near other Brassica family crops like cabbage or broccoli to reduce pest pressure. Crop rotation helps too.
Harvesting Arugula
One of the best parts of growing arugula is how quickly and continuously you can harvest it.
- Baby arugula: Ready in about 20 days. Cut when leaves are 2–3 inches long for the most tender texture.
- Mature leaves: Harvest after 35–40 days for larger, spicier greens.
- Cut-and-come-again: Trim outer leaves with scissors, leaving the center intact so the plant can keep producing.
For extended harvests, sow new seeds every 2–3 weeks for a constant supply of fresh greens.
How to Use Arugula in the Kitchen
Arugula’s peppery flavor adds sophistication to any dish. Here are some delicious ways to enjoy it:
- Fresh Salads: Toss with olive oil, lemon, and shaved Parmesan for a simple classic.
- Pizza Topping: Add fresh arugula to your pizza after baking for a gourmet touch.
- Pasta and Grains: Mix into warm pasta, quinoa, or couscous for extra flavor and color.
- Sandwiches and Wraps: Layer arugula instead of lettuce for a zesty bite.
- Pesto: Blend with garlic, olive oil, and nuts for a spicy twist on traditional basil pesto.
- Smoothies: Combine baby arugula with fruits like pear or pineapple for a refreshing, vitamin-packed drink.
Arugula pairs beautifully with ingredients like citrus, nuts, goat cheese, and balsamic vinegar — making it a chef’s favorite.
Health Benefits of Arugula
Don’t be fooled by its delicate appearance — arugula is a nutrient powerhouse. Just one cup of raw arugula provides:
- High levels of vitamin K for bone and heart health.
- Vitamin A and C for immune support and skin vitality.
- Calcium and magnesium for muscle and nerve function.
- Antioxidants that help combat inflammation and cellular damage.
It’s also low in calories and high in fiber, making it a great choice for anyone pursuing a healthy, balanced diet.
Companion Planting Tips
Arugula makes an excellent companion in your vegetable garden. It grows well with:
- Carrots and radishes: These root crops help loosen the soil around arugula.
- Herbs like dill and mint: Their strong scents help deter pests.
- Lettuce and spinach: Combine for a mixed salad garden bed.
Avoid planting near broccoli, kale, or mustard greens, which attract similar pests.
Growing Arugula in Containers
Short on garden space? No problem — arugula thrives in pots!
- Choose a container at least 6 inches deep with drainage holes.
- Use rich, well-draining potting soil.
- Water often, as containers dry out faster than ground soil.
- Place in partial sun, especially in hot climates.
You can easily grow arugula on a balcony, porch, or windowsill, making it perfect for urban gardeners.
