Why Grow Microgreens? A Tiny Garden with Big Rewards
Microgreens, those tender young seedlings, are more than just a pretty garnish. They are a powerhouse of flavor and nutrients, packed into a tiny package. Growing microgreens at home is incredibly simple, requiring minimal space and equipment. Whether you're a seasoned gardener or just starting your plant journey, microgreens offer a fast, rewarding, and delicious experience. You can enjoy fresh, nutrient-rich greens year-round, right from your kitchen counter.
What Are Microgreens, Exactly?
Microgreens are seedlings of edible vegetables and herbs, harvested when they are between 1-3 inches tall, typically 7-14 days after germination. They are harvested after the cotyledon leaves (the first leaves to emerge) have fully developed, and sometimes after the first true leaves have appeared. Microgreens are distinct from sprouts, which are germinated seeds eaten whole, including the root. Sprouts require no soil or sunlight, while microgreens need both.
Nutritional Powerhouses
Don't let their small size fool you. Microgreens are incredibly nutritious. Studies have shown that microgreens can contain significantly higher levels of vitamins and minerals compared to their mature counterparts. For example, a study published in the Journal of Agricultural and Food Chemistry found that microgreens often contain 4 to 40 times higher concentrations of nutrients like vitamins C, E, and K, as well as beta-carotene, than the mature leaves of the same plants (Xiao, Z., et al., 2012). This makes them a fantastic addition to any healthy diet.

Choosing the Right Seeds: What Can You Grow?
The possibilities are nearly endless when it comes to choosing seeds for your microgreen garden. Popular choices include:
- Brassicas: Broccoli, cauliflower, kale, cabbage, arugula, mustard greens, kohlrabi
- Legumes: Peas, lentils, chickpeas, soybeans
- Cereals: Wheat, barley, rice, oats, corn
- Herbs: Basil, cilantro, dill, parsley, chives
- Vegetables: Radish, beets, carrots, celery
- Salad Greens: Lettuce, spinach, endive, cress
Important Considerations:
- Seed Source: Choose high-quality seeds specifically labeled for sprouting or microgreen production. Avoid seeds that have been treated with fungicides or other chemicals. Look for certified organic seeds whenever possible.
- Taste Preferences: Consider your personal taste preferences when selecting seeds. Some microgreens, like radish, have a spicy kick, while others, like sunflower, offer a mild, nutty flavor.
- Growth Rate: Different seeds have different germination and growth rates. Consider combining seeds with similar growth rates for a more uniform harvest.
Setting Up Your Microgreen Garden: Simple Supplies
You don't need fancy equipment to grow microgreens. Here's a basic list of what you'll need:
- Growing Trays: Shallow trays with drainage holes are ideal. You can repurpose plastic food containers or purchase specialized microgreen trays. A solid tray to place underneath to catch drainage is also important.
- Growing Medium: Seed starting mix, coco coir, or a soilless mix works well. Avoid using garden soil, as it can harbor pests and diseases.
- Seeds: As discussed above, choose your seeds carefully.
- Spray Bottle: For misting the seeds and seedlings.
- Light Source: A sunny windowsill with at least 4-6 hours of direct sunlight is sufficient for many microgreens. If you don't have enough natural light, consider using a grow light.
- Water: Filtered water is best.
Step-by-Step Guide to Growing Microgreens
Follow these easy steps to grow your own microgreens at home:
- Prepare the Growing Tray: Fill the growing tray with your chosen growing medium, leaving about an inch of space at the top. Gently level the surface.
- Sow the Seeds: Sprinkle the seeds evenly over the surface of the growing medium. Don't overcrowd them; aim for a dense but not packed layer.
- Water the Seeds: Gently mist the seeds with water using a spray bottle. You want to moisten the seeds and the growing medium without oversaturating them.
- Cover the Tray: Cover the tray with a lid or another tray to create a dark, humid environment. This will help with germination.
- Monitor Germination: Check the seeds daily and mist them as needed to keep them moist. Most seeds will germinate within 2-5 days.
- Introduce Light: Once the seeds have germinated, remove the cover and move the tray to a sunny windowsill or under a grow light.
- Water Regularly: Continue to mist the microgreens regularly, keeping the growing medium moist but not soggy. You can also bottom-water by adding water to the tray beneath the growing tray.
- Harvesting Your Microgreens: Your microgreens will be ready to harvest in 7-14 days, depending on the variety. Use scissors or a sharp knife to cut the stems just above the soil line.
- Enjoy Your Harvest: Rinse the harvested microgreens and enjoy them immediately. Microgreens are best eaten fresh but can be stored in the refrigerator for a few days.
Troubleshooting: Common Problems and Solutions
- Mold: Mold growth is often caused by excessive moisture and poor air circulation. To prevent mold, ensure good air circulation by using a small fan. You can also try diluting hydrogen peroxide with water (1 part hydrogen peroxide to 10 parts water) and spraying it on the affected areas.
- Damping Off: Damping off is a fungal disease that can kill seedlings. To prevent damping off, use a sterile growing medium and avoid overwatering.
- Leggy Growth: Leggy growth occurs when seedlings don't receive enough light. Move the tray to a brighter location or use a grow light.
- Uneven Germination: Uneven germination can be caused by inconsistent watering or poor seed quality. Ensure consistent watering and use high-quality seeds.
Using Grow Lights for Microgreens
While a sunny windowsill can work, using grow lights provides more consistent and reliable results, especially during the shorter days of winter. LED grow lights are energy-efficient and provide the full spectrum of light that microgreens need to thrive. Place the grow light a few inches above the microgreens for best results.
Microgreens in the Kitchen: Culinary Delights
Microgreens are incredibly versatile in the kitchen. Use them to:
- Garnish Dishes: Add a pop of color and flavor to salads, soups, sandwiches, and appetizers.
- Boost Smoothies: Blend microgreens into your smoothies for an extra dose of nutrients.
- Top Pizzas and Tacos: Sprinkle microgreens on top of pizzas and tacos for added flavor and texture.
- Enhance Egg Dishes: Add microgreens to omelets, scrambled eggs, and frittatas.
- Elevate Stir-Fries: Toss microgreens into stir-fries for a fresh, flavorful touch.
Expanding Your Microgreen Garden
Once you've mastered the basics, experiment with different varieties of seeds and growing techniques. Try growing microgreens in different containers, such as mason jars or repurposed containers. You can also explore different growing mediums, such as hemp mats or jute mats.
The Environmental Benefits of Growing Microgreens at Home
Growing your own microgreens is not only good for your health but also for the environment. By growing your own food, you reduce your reliance on commercially grown produce, which often travels long distances and requires significant resources. Microgreens require very little water and energy to grow, making them a sustainable choice. You can even compost the used growing medium and roots, further reducing your environmental impact.
