Collecting Arugula Seeds

Arugula, also known as rocket, is a nutritious green that thrives in various climates. Harvesting its seeds is essential for future plantings. In this guide, we’ll explore how to collect arugula seeds efficiently.

When temperatures rise, arugula tends to bolt, which means it starts producing seeds. This process is natural, but if you want to enjoy more of your greens, harvest them before they bolt. Plants like arugula will produce more leaves if you pick them frequently. However, if left unattended, they will begin to focus on seed production.

Selecting the Best Plants for Seeds

Choosing plants with desirable traits ensures better crops in future seasons. Look for arugula plants that are slow to bolt, have a delicious flavor, and show resistance to pests. These qualities will be passed on to the next generation, giving you a robust and tasty crop.

As arugula begins to seed, it grows taller and produces a stalk with white flowers. These flowers will eventually turn into seed pods. The process starts with blooming and progresses to pod formation. Once the seed pods are brown and dry, they are ready to be harvested.

Harvesting Seed Pods

To collect the seeds, follow these steps:

Wait for Dry Pods
Ensure the seed pods are completely dried and browned on the plant before cutting them off.

Cutting the Pods
Use sharp scissors or garden shears to cut the seed pods and stalks from the plant.

Extracting Seeds
Gently squish the dried pods to release the tiny black seeds. If they are ready, the pods will open easily.

Separating Seeds from Plant Matter

After collecting the seeds, it’s crucial to separate them from any remaining plant material. Lay the seeds on a flat surface, such as a sheet or a tray, and carefully remove any debris. Ensuring that the seeds are free of plant matter helps prevent mold and ensures better storage.

Drying and Storing Seeds

To preserve arugula seeds for future planting:

Final Drying Stage
Place the cleaned seeds in an envelope or jar. Ensure they are completely dry to prevent mold growth.

Store the envelope or jar in a cool, dark place. Properly stored seeds can last several years and will be ready for your next planting season.


Collecting arugula seeds is a rewarding process that ensures a continuous supply of this flavorful green. By selecting the best plants and following these simple steps, you can successfully harvest and store arugula seeds.
