Cultivating Arugula Microgreens

Before you embark on your growing journey, it's essential to gather the necessary materials and prepare your setup. This section will guide you through the key elements you'll need to get started with cultivating thriving microgreens.

Essential Supplies and Equipment

To set up a successful arugula microgreens garden, here's a list of supplies and equipment you'll need:

1. Growing Trays or Containers:

Choose shallow trays or containers with drainage holes to prevent waterlogging and promote proper airflow.

2. Growing Medium:

Opt for a high-quality, soilless growing medium such as peat moss, coconut coir, or a commercial seed-starting mix. These mediums provide excellent drainage, aeration, and moisture retention.

3. Arugula Seeds:

Select arugula seeds specifically labeled for microgreens. Ensure they are untreated and of good quality for optimal germination and growth.

4. Spray Bottle:

Use a spray bottle to mist the seeds and seedlings gently, providing them with adequate moisture without causing damage.

5. Light Source:

Adequate lighting is crucial for healthy microgreen growth. Consider using full-spectrum LED grow lights or placing your trays near a sunny window where they can receive 12-16 hours of indirect sunlight.

6. Water Source:

Have a source of clean, filtered water readily available for watering your microgreens.

7. Labels:

Use labels or markers to identify the varieties and planting dates of your microgreens.

8. Scissors or Harvesting Tool:

Prepare a clean and sharp pair of scissors or a harvesting tool for when it's time to harvest your mature microgreens.

Selecting High-Quality Arugula Seeds

Choosing the right arugula seeds is crucial for successful microgreen cultivation. Look for reputable seed suppliers or online stores that specialize in microgreen seeds. Ensure the seeds are fresh, viable, and specifically labeled for microgreens.

Preparing the Growing Medium

Prepare your growing medium by moistening it with water before sowing the seeds. Follow the instructions provided by the manufacturer or soak the medium until it reaches a consistently damp but not waterlogged state. Avoid compacting the growing medium excessively as it can hinder root development and drainage.

Proper preparation of supplies and equipment ensures a smooth and productive growing experience. In the next section, we will delve into the step-by-step process of planting and growing your arugula microgreens, bringing you closer to enjoying your homegrown nutritious greens.

Planting and Growing

Now that you have your supplies ready, it's time to dive into the exciting process of planting and growing your arugula microgreens. Follow these steps to ensure successful cultivation and vibrant growth.

Seed Soaking and Rinsing

Begin by soaking the arugula seeds in clean water for about 4-6 hours. This helps jumpstart the germination process and enhances seed viability. After soaking, thoroughly rinse the seeds under running water to remove any residual debris.

Choosing the Appropriate Growing Tray or Container

Select a shallow tray or container with drainage holes to prevent water accumulation. The size of the container will depend on the quantity of microgreens you intend to grow. Ensure the chosen tray or container fits comfortably in your chosen growing area.

Sowing Seeds and Optimal Spacing

Spread a thin, even layer of pre-moistened growing medium in the tray or container. Sprinkle the rinsed arugula seeds evenly across the surface, aiming for a dense but not overcrowded distribution. Gently press the seeds into the growing medium to ensure good seed-to-soil contact.

Proper Watering and Light Conditions

After sowing the seeds, mist the surface with water using a spray bottle. Be careful not to oversaturate the growing medium; aim for a consistently moist environment. Water the microgreens regularly, keeping the growing medium moist but not waterlogged.

Provide your greens with adequate lighting. If using grow lights, position them approximately 4-6 inches above the tray to ensure optimal light intensity. If relying on natural sunlight, place the tray near a bright window where the microgreens can receive indirect sunlight for 12-16 hours per day.

Managing Temperature and Humidity

Maintain an ideal temperature range of around 65-75°F (18-24°C) for your arugula microgreens. Avoid exposing them to extreme temperature fluctuations or drafts, as this can affect their growth and health. Additionally, ensure proper airflow to prevent the development of mold or fungal issues. Using a small fan or opening a nearby window can help maintain good air circulation.

Regularly monitor the humidity levels around your greens. Aim for moderate humidity to prevent excessive moisture retention, which can lead to damping-off disease or mold growth. If needed, use a hygrometer to measure humidity levels and adjust as necessary.

By following these planting and growing steps, you'll set a solid foundation for your arugula microgreens to thrive. In the next section, we'll delve into caring for your microgreens as they develop and mature, ensuring they reach their full potential.

Caring for Arugula Microgreens

Proper care is essential to ensure healthy and robust growth. By following these care guidelines, you'll provide an optimal environment for their growth and development.

  1. Watering: Check the moisture level of the growing medium regularly and water as needed. Avoid overwatering, as it can lead to fungal issues. Use a spray bottle or a gentle watering method to moisten the growing medium without causing disturbance to the delicate greens.
  2. Light Exposure: Ensure your tiny greens receive adequate light exposure. Adjust the position of grow lights or rotate trays near the window to ensure even lighting distribution. Maintain the recommended 12-16 hours of light per day.
  3. Air Circulation: Good airflow is crucial for preventing mold or fungal growth. Provide gentle air circulation by using a small fan set on a low setting or by opening a nearby window periodically. 

Monitoring Growth and Adjusting Light Exposure

Monitor the growth of your arugula microgreens as they develop. You'll notice the emergence of tiny cotyledon leaves followed by the development of true leaves. Adjust the lighting distance or intensity based on the growth stage. If they appear leggy or stretched, it's a sign that they are not receiving enough light. In this case, move the lights closer or increase their intensity slightly.

Avoiding Common Pitfalls and Challenges

  1. Overcrowding: Ensure proper spacing when sowing microgreen seeds to prevent overcrowding. Crowded greens can lead to poor airflow, increased humidity, and higher chances of disease or mold development.
  2. Disease and Pests: Monitor them for signs of disease or pests. Common issues include damping-off, fungal infections, or small insect infestations. Promptly address any problems by adjusting environmental conditions, improving airflow, or applying organic pest control methods if necessary.
  3. Nutrient Deficiencies: Arugula microgreens generally don't require additional fertilization during their short growing period. However, if you notice signs of nutrient deficiencies such as pale or yellowing leaves, you may need to consider light fertilization using a diluted organic liquid fertilizer.

With regular care and attention, your arugula superfoods will thrive and reach their full potential. In the next section, we'll explore the exciting process of harvesting and storing your homegrown microgreens for ultimate freshness and flavor.

Harvesting and Storage

Harvesting arugula microgreens at the right time ensures peak flavor, texture, and nutritional value. Follow these guidelines for proper harvesting and storage techniques to enjoy your homegrown greens at their best.

Recognizing the Right Time to Harvest

Arugula Microgreens are typically ready for harvest around 10-14 days after sowing, depending on the desired size and growth rate. Look for the following indicators to determine the optimal harvest time:

  1. Height: They should reach a height of 1-2 inches, with well-developed cotyledon leaves and true leaves starting to emerge.
  2. Color: The leaves should display vibrant green coloration, indicating their vitality and optimal nutritional content.
  3. Flavor: Gently taste a few leaves to assess their flavor. They offer a mildly spicy and peppery taste. Harvest when the flavor is at its peak and suits your preferences.

Techniques for Harvesting Arugula Microgreens

To harvest your greens, use clean and sharp scissors or a harvesting tool. Follow these steps:

  1. Hold the base of the microgreen with one hand to stabilize it.
  2. Position the scissors or tool close to the soil level.
  3. Make a clean and swift cut, snipping the microgreens just above the soil line.
  4. Repeat this process for each green, working your way through the tray or container.

Proper Storage to Maintain Freshness and Quality

To maintain the freshness and quality of your harvested microgreens, follow these storage recommendations:

  1. Cleaning: Gently rinse the harvested microgreens with cool water to remove any soil or debris. Use a salad spinner or pat them dry with a clean kitchen towel.
  2. Storage Containers: Place the dry microgreens in a breathable storage container, such as a shallow container or a paper towel-lined plastic bag with small holes for air circulation. Avoid tightly sealing the container, as it can cause moisture buildup and lead to wilting.
  3. Refrigeration: Store the container of your greens in the refrigerator at a temperature of around 35-40°F (2-4°C). The cool temperature helps preserve freshness and extends the shelf life.
  4. Shelf Life: Arugula microgreens can typically be stored for up to 5-7 days under proper refrigeration conditions. However, it's best to consume them as soon as possible to enjoy their peak flavor and nutritional benefits.

By following these harvesting and storage practices, you'll maximize the longevity and quality of your greens, ensuring a steady supply of fresh greens for your culinary creations.

Frequently Asked Questions About Arugula Microgreens

Are arugula microgreens healthier than mature arugula?

Most microgreens have higher levels of vitamins and minerals than their mature counterparts. Arugula microgreens, in particular, have higher levels of vitamin K1, lutein, and manganese, among others.

This makes these tiny superfoods a perfect food supplement for athletes, people with weakened immune systems, or vegetarians and vegans.

What is the difference between microgreens and sprouts?

Many people think microgreens and sprouts are the same thing, but they are not. Of course, they both have something in common, but there are also many differences.

Sprouts are seedlings from seeds that have not yet developed roots and have not yet completed photosynthesis. sprouts, on the other hand, are plants that have already developed roots and are therefore larger than shoots.

Microgreens are small-leafed plantlets that are usually used as toppings for soups, salads, or other dishes. They have a very intense flavor and often also a special color. While sprouts are often eaten at a very early germination time, microgreens have more time to grow and more time to develop nutrients and flavor. For this to succeed, microgreens need either soil or a corresponding mat of flow from which the nutrients can be drawn, as well as water and sunlight, of course. Microgreens are then harvested a little later after about 5-7 days and eaten without the root. The flavor of microgreens is much more intense than sprouts and the nutrient content is many times higher.

Can I use regular arugula seeds for microgreens?

It is advisable to use specific arugula microgreen seeds for optimal results, as they are specially selected and bred for microgreen cultivation. These seeds germinate quicker and yield better results than regular arugula seeds.

Ingarden's microgreen seeds come from trusted and certified organic growers in the region of Emilia Romagna in Italy, as well as the Netherlands. Our seeds are strictly confirmed organic by accredited authorities, ensuring that no artificial fertilizers, herbicides, or pesticides are used in their production.

Each batch of seeds undergoes laboratory testing for microbiological safety according to HACCP standards. Germination rates are guaranteed at 90%, and the seeds are inspected for their quality and integrity. They are handled only by certified organic manufacturers who adhere to strict hygiene standards to prevent cross-contamination.

Can you eat arugula microgreens?

Yes, you can eat arugula microgreens! In fact, they are a popular ingredient in salads, smoothies, wraps, and other dishes. These microgreens are not only delicious but also highly nutritious, containing a range of vitamins, minerals, and antioxidants. However, it's important to note that while arugula microgreens are generally safe to eat, you should always wash them thoroughly before consuming to remove any dirt, bacteria, or pesticides that may be present, especially if they are store-bought. Additionally, if you have any allergies or medical conditions, it's always a good idea to consult with a healthcare professional before adding new foods to your diet.

Can i replace vegetables with microgreens?

Microgreens are young, tender plants grown from seeds and typically harvested within 1-2 weeks. Although they are small, they are packed with nutrients and have an intense aroma and flavor. It is possible to incorporate these tiny superfoods into a balanced diet, but it is unlikely that they can replace an adequate amount of vegetables.

Vegetables provide many nutrients, including fiber, vitamins, minerals, and phytonutrients that are important for health. While microgreens contain some of these nutrients in higher concentrations than mature plants, they typically lack fiber and a broader nutrient profile.

If you want to replace vegetables with microgreens, you should make sure to use a variety of types to ensure that you get a broader nutrient profile. It is also important to incorporate other sources of fiber, such as whole grains, legumes, and fruits, into your diet.

Overall, microgreens can be a healthy addition to a balanced diet, but they should not be used as a substitute for vegetables.
