Microgreens have become a popular choice for health-conscious individuals and home gardeners alike. These small but mighty greens are packed with nutrients and can be grown easily in various environments. Whether you’re an urban dweller with limited space or a seasoned gardener looking to diversify your crops, microgreens offer a rewarding and nutritious option.
What Are Microgreens?
Microgreens are young, edible seedlings of vegetables and herbs. They are typically harvested within 7-21 days after germination, just after the first true leaves have developed. Unlike sprouts, which are consumed with their roots, microgreens are cut above the soil, leaving the root system behind.
They come in various flavors, colors, and textures, depending on the type of plant. Common varieties include:
- Arugula: Peppery and spicy, great for adding a kick to salads.
- Radish: Crisp and mildly spicy, perfect for sandwiches and garnishes.
- Cilantro: Bold and citrusy, ideal for Mexican and Asian dishes.
- Beet: Earthy and sweet, adds vibrant color to any plate.
- Basil: Aromatic and sweet, excellent for Italian cuisine.
How to Grow Microgreens
Growing them at home is a simple process that can be done indoors or outdoors, making it accessible to everyone, regardless of space constraints. Here’s a step-by-step guide to growing your own young plants:
Step 1: Choosing the Right Seeds
Selecting the right seeds is crucial for a successful microgreen harvest. While you can use regular vegetable or herb seeds, it’s best to choose seeds specifically labeled for microgreens. These seeds are often untreated and have a high germination rate, ensuring a healthy and abundant crop.
Some popular seeds include:
- Sunflower: Nutty and crunchy, a favorite for salads and snacks.
- Pea Shoots: Sweet and tender, great for stir-fries and salads.
- Broccoli: Mild and slightly bitter, rich in nutrients.
- Chia: Mucilaginous seeds that form a gel when wet, offering unique growing challenges and nutritional benefits.
Step 2: Preparing the Growing Medium
The growing medium is the foundation of your microgreen. You can choose from several options:
- Soil: A common choice for growing green plants, soil provides essential nutrients and is easy to work with. Organic potting soil is ideal, as it ensures your microgreens are chemical-free.
- Coconut Coir: Made from coconut husks, coir is a sustainable, pH-neutral growing medium that retains moisture well.
- Hydroponic Mats: For a soil-free option, hydroponic mats made from materials like jute or felt can be used. They provide a clean and convenient way to grow microgreens, especially indoors.
Fill your container with the growing medium, leaving about half an inch of space at the top. Moisten the medium thoroughly with water before planting your seeds.
Step 3: Sowing the Seeds
When sowing seeds, it’s important to distribute them evenly across the surface of the growing medium. They are typically grown densely, so don’t worry about spacing the seeds too far apart.
- Sprinkle the Seeds: Evenly scatter the seeds across the surface of the growing medium. A denser planting will yield more microgreens, but be careful not to overcrowd the seeds, as this can lead to poor air circulation and mold growth.
- Pressing the Seeds: After sowing, gently press the seeds into the growing medium with your hand or a flat tool to ensure good contact with the soil or mat. This helps with germination.
Step 4: Germination and Initial Care
After planting, the seeds need a warm and humid environment to germinate. Cover the tray with a lid, another tray, or a damp cloth to retain moisture and warmth.
- Dark and Warm Environment: Place the covered tray in a dark, warm area such as a cupboard or closet. Most microgreens germinate best at temperatures between 65°F and 75°F (18°C to 24°C).
- Daily Check: Check the trays daily to ensure the growing medium remains moist. Use a spray bottle to mist the surface if it begins to dry out.
Step 5: Light Exposure and Growth
Once the seeds have germinated, typically within 3-7 days, it’s time to introduce them to light. Remove the cover and place the tray in a well-lit area or under grow lights.
- Sunlight: A south-facing windowsill is ideal for them, as it provides ample sunlight. However, too much direct sunlight can cause the plants to become leggy, so monitor them closely.
- Grow Lights: If natural light is insufficient, especially in winter, consider using grow lights. LED grow lights are energy-efficient and provide the full spectrum of light needed for healthy growth. Position the lights about 12-18 inches above the tray, and keep them on for 12-16 hours a day.
Step 6: Watering
Proper watering is crucial for healthy green plants. Too much water can lead to mold and root rot, while too little will cause the plants to wilt.
- Bottom Watering: To avoid disturbing the delicate seedlings, use the bottom watering method. Place the tray in a shallow pan of water, allowing the growing medium to absorb water through the drainage holes. Remove the tray once the top layer of the medium is moist.
- Misting: Alternatively, you can mist the microgreens with a spray bottle, but be careful not to overdo it.
Step 7: Harvesting Microgreens
New plants are ready to harvest when they are about 2-3 inches tall and have developed their first set of true leaves. This usually occurs 7-14 days after germination, depending on the variety.
- Using Scissors: Use sharp scissors or a knife to cut the microgreens just above the soil or growing mat. Harvest only as much as you need, as they are best eaten fresh.
- Multiple Harvests: Some microgreens, like pea shoots and sunflower, can regrow after the first harvest. Allow them to grow for another week or two for a second cutting.
Step 8: Post-Harvest Care
After harvesting, it can be stored in the refrigerator for up to a week, although they are most nutritious and flavorful when eaten fresh.
- Storage: Place the harvested plants in a breathable container or wrap them in a paper towel to absorb excess moisture. Store them in the crisper drawer of your refrigerator.
- Cleaning: If you plan to reuse the trays, clean them thoroughly with soap and water to prevent the spread of mold or disease in future crops.
