How To Grow Arugula Microgreens

Before diving into the cultivation of arugula microgreens, it's important to grasp some basic knowledge about these little plants.

1. Growth Cycle: Arugula microgreens typically germinate in 2-3 days, and within a week to 10 days, they're ready for harvesting. This quick turnaround time allows for multiple harvests in a short period.

2. Lighting: Arugula microgreens prefer a well-lit area. Natural sunlight is perfect, but if that's not available, a basic fluorescent or LED grow light will suffice.

3. Watering: Watering needs are relatively low for arugula microgreens. Consistent moisture is key, but be cautious not to overwater as this can lead to mold and fungus problems.

4. Temperature: These microgreens are relatively hardy and can grow in a wide range of temperatures, but they prefer cooler conditions, between 60-70°F (15-20°C).

In order to successfully grow arugula microgreens at home, here are the materials you'll need:

1. Arugula Seeds: Arugula seeds are readily available at local garden centers, or you can order them online.

2. Growing Medium: A soilless growing medium, like coconut coir or a high-quality potting mix, is recommended for growing microgreens. They provide excellent water retention and make it easy for the tiny roots to establish themselves.

3. Growing Trays: You'll need shallow growing trays to plant your seeds. Some gardeners prefer trays with drainage holes to prevent waterlogging.

4. Spray Bottle: A spray bottle is necessary to mist the seeds daily, ensuring they receive adequate moisture.

5. Grow Lights (optional): If you don't have a bright, sunny window, you might need a fluorescent or LED grow light to provide the necessary light for your microgreens.

6. Harvesting Tools: A pair of clean, sharp scissors or a sharp knife will be necessary when it comes time to harvest your arugula microgreens.

With these materials in hand, you'll be well-equipped to start your journey into growing arugula microgreens at home.

Step 1. Prepare The Grow Tray

One will sit beneath the other and be filled with water to hydrate the roots of your microgreens, while also preventing mold growth.

To set this up, take the tray without drainage holes and fill it with coco coir. Smooth out the surface and then mist it thoroughly with a spray bottle. If a spray bottle is unavailable, lightly sprinkle water over the coco coir until it is well-hydrated.

Do not add water to the lower tray yet. To create drainage holes in the top tray, use a sharp knife to carefully poke small holes.

Step 2. Add The Seeds

Arugula seeds do not need pre-soaking.

Spread them evenly across the surface of the coco coir in the prepared tray.

Aim for a uniform distribution to avoid overcrowding, which could lead to growth problems.

Be careful not to scatter too many or too few seeds.

Step 3. Water And Cover The Seeds

After sowing, mist the seeds gently.

Do not cover the seeds with additional soil.

Instead, place another container on top to darken the environment for 2-3 days.

This blackout phase is crucial for Arugula seeds, and adding some weight helps ensure the roots penetrate deeply into the soil, promoting straight and tall growth.

Keep your tray in a location with a consistent temperature between 65 to 75 degrees Fahrenheit, an ideal range for germination.

Continue to hydrate the seeds by misting them approximately every 10-12 hours.

Step 4. Uncover And Give Light

Around day 2 or 3, inspect your arugula seeds' growth.

If they're germinating well, it's time to remove the cover and introduce light.

Provide at least 12 hours of light daily to encourage healthy growth. A grow light is recommended to avoid the leaning that can occur when growing next to a window.

Step. 5 Check Daily

Maintain the lighting for 4 to 10 days, ensuring good airflow and low humidity in your growing area to ward off potential mold issues.

From this point until harvest, your microgreens need a balanced hydration strategy.

This is the time to start watering using the tray below, which will keep the leaves dry and further help to prevent mold.

Troubleshooting Common Arugula Microgreens Growing Challenges

Arugula microgreens, while generally easy to grow, can still present a few challenges.

Here's how to tackle some common problems:

Slow or Uneven Germination:

If your arugula microgreens are germinating slowly or unevenly, it may be due to inconsistent moisture levels, incorrect temperature, or poor seed quality.

Ensure your seeds are moist but not overly saturated and that they're kept at a steady temperature of 65 to 75 degrees Fahrenheit.

If issues persist, consider sourcing your seeds from a different supplier.


Mold is often the result of poor ventilation or excessive humidity. It can also occur if you're watering from the top or if the seeds are overcrowded.

To avoid mold, ensure your microgreens have good airflow, use the tray watering method, and keep the growing medium moist but not waterlogged.

Leggy Microgreens:

If your arugula microgreens are growing long and thin or are bending towards the light, they might not be getting enough light.

Position your grow lights directly above the microgreens and keep them on for at least 12 hours a day.

If you're using natural light, remember it may not be as intense as a grow light and additional lighting may be necessary.

Pale or Yellow Microgreens:

Lack of light can cause your arugula microgreens to appear pale or yellow. Providing sufficient light (12-16 hours per day) will promote chlorophyll production, leading to healthy, vibrant green microgreens.

Poor Flavor or Tough Texture:

The quality of your growing medium and water can affect the taste and texture of your microgreens. If you're unsatisfied with the flavor or texture, consider switching to high-quality organic soil and using filtered water.

Good hygiene, sufficient light, consistent moisture, and quality materials are key to successfully growing arugula microgreens.

If problems arise, don’t get disheartened. Gardening is a process of learning and adapting, and with time, you'll be able to perfect your method.

How To Harvest Arugula Microgreens

After 8 to 10 days, your arugula microgreens should be ready to harvest. To do so, wait at least 12 hours after watering and once they've reached approximately 2 inches in height. Using scissors, harvest the top one and a half inches of the shoots.

Congratulations! You've now successfully grown arugula microgreens.

Washing and Drying Arugula Microgreens

Thoroughly rinse your harvested arugula microgreens under cold water using a colander. To dry them, spread them out on paper towels and let them air dry.

To expedite the drying process, you may use a fan on a slow setting. Freshly cut microgreens are best consumed immediately after drying.

Storing Arugula Microgreens

You may be wondering how to store your harvested arugula microgreens. It's quite simple - just loosely place them in a bowl or container and store them in the refrigerator.

Arugula microgreens are treasured by food enthusiasts and chefs alike for their zesty, nutty flavor that brings a punch to many dishes.

These microgreens can be incorporated into salads, soups, sandwiches, and even baked goods.

2. Prevents Osteoporosis

The importance of calcium and magnesium on bone health is well known, and deficiencies in these minerals can lead to osteoporosis. Luckily, as you can see from the nutritional chart above, Arugula microgreens contain many minerals like calcium, phosphorus, and magnesium, which are essential for bone strength.

3. Helps Regulate Neural Function

Arugula contains a lot of potassium as seen in the chart above, and potassium is well known for its ability to affect brain function dramatically. There are potassium currents in the brain that play a major role in moderating and regulating electrical currents throughout the body. (2)

4. Boosts Metabolism

Adequate amounts of potassium are also needed to ensure optimum utilization of food for protein synthesis and growth. This overall impacts tissue regeneration, cell growth, and balanced metabolism. (3)

5. Stabilizes Blood Sugar Levels

Potassium has been found to stabilize blood sugar levels and reduce the chance of developing diabetes. Low levels of potassium have also been associated with a higher risk of developing diabetes according to one study. (4)
