Can I let my arugula flower?

While arugula does produce small white flowers, allowing it to flower can make the leaves bitter. To enjoy the best flavor, it’s recommended to harvest before flowering.

Selecting the Right Arugula Variety

Before you begin planting, consider the different arugula varieties available. You can choose from wild arugula, which has a stronger flavor, or cultivated varieties that offer a milder taste. Some varieties are better suited for specific growing conditions, so choose one that aligns with your climate and preferences.

Preparing the Soil for Planting

Arugula thrives in well-draining soil with a pH level between 6.0 and 6.8. Prepare your garden bed by loosening the soil to a depth of about 6 inches. Incorporate organic compost or well-rotted manure to improve soil fertility and structure. Proper soil preparation sets the foundation for healthy arugula growth.

Planting Arugula Seeds

Sow arugula seeds directly into the prepared soil. Plant the seeds about ½ inch deep and space them around 1 inch apart. You can create rows or scatter the seeds across the bed. After planting, lightly water the soil to ensure good seed-to-soil contact.

Providing Optimal Growing Conditions

Arugula thrives in cooler temperatures, ideally ranging from 50°F to 65°F (10°C to 18°C). It’s a cool-season crop that can tolerate light frosts. Place your arugula bed in a location that receives partial sunlight, especially during the warmer months. Adequate sunlight is crucial for healthy leaf development.

Caring for Arugula Seedlings

Once the arugula seedlings emerge, thin them out to provide enough space for growth. Leave about 4 to 6 inches of space between each seedling. Regularly water the plants to keep the soil consistently moist but not waterlogged. Mulching around the plants can help retain soil moisture and prevent weed growth.

How to Harvest Arugula So It Keeps Growing

Harvesting arugula correctly ensures that your plant continues to produce fresh leaves for an extended period. Here’s how to harvest arugula to promote ongoing growth:

Harvesting Young Leaves

Young arugula leaves are the most tender and flavorful. Begin harvesting when the leaves are around 2 to 3 inches in length. Use clean, sharp scissors or garden shears to snip off the outer leaves, leaving the center of the plant intact. This encourages the plant to keep producing new leaves from the center.

Regular Harvesting

Frequent harvesting is key to prolonging the arugula’s harvest period. You can typically harvest arugula every 1 to 2 weeks, depending on the rate of growth. As long as the plant continues to produce new leaves, you can enjoy a steady supply of fresh arugula for your culinary creations.

Avoiding Flowering

Allowing arugula to flower can signal the end of its leaf production phase. When the plant starts to send up flower stalks, its energy is diverted from leaf growth to flowering and seed production. To prevent this, consistently harvest the leaves and pinch off any flower buds that appear.

Post-Harvest Care

After each harvest, give your arugula plants a light feeding of balanced liquid fertilizer to support their growth. Water the plants if the soil feels dry to the touch. Keeping the arugula well-fed and adequately watered encourages continuous leaf production.

By following these guidelines for growing and harvesting arugula, you’ll be well on your way to cultivating a bountiful supply of fresh, peppery greens that can enhance your meals throughout the growing season. Enjoy the rewards of your efforts as you savor the vibrant flavors of homegrown arugula in your dishes.


Growing arugula is a rewarding experience that offers fresh and flavorful greens for your culinary delights. By following the steps outlined in this guide, you’ll be well on your way to cultivating healthy arugula plants in your own garden. Remember to consider factors like variety, soil preparation, care, and harvesting techniques for a successful arugula-growing journey.
