Arugula, also known as rocket or roquette, is a fast-growing, cool-season green that adds a tangy, peppery flavor to salads. This leafy green is packed with nutrients and is easy to grow, making it a popular choice for home gardeners. In this guide, we will explore the best practices for planting arugula, focusing on the ideal patterns and spacing for optimal growth.
Understanding Arugula
Before we delve into the planting process, it’s essential to understand the nature of arugula. Arugula is a member of the Brassicaceae family, which includes broccoli, cabbage, and kale. It’s a hardy plant that can tolerate a range of conditions, but it thrives in cooler temperatures. Arugula is also a fast grower, often ready to harvest just four to six weeks after planting.
Arugula is a versatile plant that can be grown in the ground, in raised beds, or in containers. It’s also a great choice for a fall garden, as it can withstand light frosts. The flavor of arugula is best when it’s grown in cool conditions, as heat can make the leaves more bitter.
Preparing the Soil
Arugula prefers well-drained soil with a pH between 6.0 and 7.0. Before planting, it’s a good idea to test your soil to ensure it’s within this range. If your soil is too acidic or too alkaline, you can adjust it with lime or sulfur, respectively.
Arugula also benefits from rich, fertile soil. Before planting, work a generous amount of compost or well-rotted manure into the soil. This will improve soil structure, increase nutrient content, and enhance the soil’s ability to retain water.
According to the USDA, incorporating organic matter into the soil can also help suppress diseases and pests, which can be beneficial for arugula and other leafy greens.

When to Plant
Arugula can be planted in the spring as soon as the soil can be worked. It can also be planted in the late summer or early fall for a fall harvest. In mild climates, arugula can be grown throughout the winter.
It’s a good idea to plant arugula in successive plantings every two to three weeks. This will ensure a continuous harvest throughout the growing season.
How to Plant
Planting arugula is a straightforward process. Here’s a step-by-step guide:
- Prepare the soil by working in compost or well-rotted manure.
- Make shallow rows or furrows in the soil about 10 inches apart.
- Sow the arugula seeds about 1/4 inch deep and 1 inch apart in the rows.
- Cover the seeds with soil and water well.
- Keep the soil evenly moist until the seeds germinate, which usually takes about 7 to 14 days.
Patterns and Spacing
Proper spacing is crucial for arugula to grow well. When the plants are too close together, they can compete for resources, which can result in smaller, less flavorful leaves.
As a rule of thumb, arugula plants should be spaced about 1 to 3 inches apart within rows, with rows spaced about 10 inches apart. This spacing allows the plants to have enough room to grow and ensures good air circulation, which can help prevent diseases.
When it comes to planting patterns, there are a few options. Some gardeners prefer to plant arugula in rows, while others prefer a more informal, scattered approach. Both methods can work well, depending on your garden layout and personal preference.
Caring for Arugula
Once your arugula is planted, it requires minimal care. Keep the soil evenly moist, but avoid overwatering, as this can lead to root rot. Arugula can tolerate some drought, but regular watering will result in the best growth and flavor.
Arugula doesn’t typically require additional fertilization after planting, especially if you’ve prepared your soil well. However, if your plants seem to be growing slowly or their leaves are pale, a balanced vegetable fertilizer can give them a boost.
Keep an eye out for pests like aphids and flea beetles, which can damage arugula. If you notice any pests, you can use organic pest control methods like insecticidal soap or neem oil.
Harvesting Arugula
Arugula can be harvested as soon as the leaves are large enough to eat, usually when they’re about 2 to 3 inches long. To harvest, simply cut the leaves with a sharp knife or scissors. Be sure to leave the center of the plant intact, as this will allow it to continue producing leaves.
Arugula can be harvested multiple times throughout the growing season. However, the leaves can become more bitter as the weather warms, so it’s best to harvest early and often.
Conclusion
Planting arugula is a rewarding endeavor that can provide you with a fresh, flavorful addition to your meals. By understanding the nature of arugula, preparing the soil properly, and following the correct planting and care instructions, you can enjoy a successful harvest.
Remember, the key to growing arugula is providing the right conditions: cool temperatures, well-drained soil, and proper spacing. With these elements in place, you’ll be well on your way to enjoying your own homegrown arugula.
