Understanding Microgreen Growing
Microgreens are tiny, edible greens that germinate from vegetables and herbs seeds. Mostly, they are obtained from the family of cruciferous vegetables including but not limited to kale, cauliflower, broccoli, and cabbage. Often confused with sprouts, microgreens differ in their growing conditions, harvesting time, and usefulness.
Microgreens are not only dense in nutrients but they are known for their diverse flavors and textures, making them a favorite for professional chefs and food enthusiasts. They can add the much-needed color, texture, and intense taste to salads, soups, sandwiches, and wraps. All this coupled with the benefits of growing them at home makes this art worthy of mastery.
The Fascinating World of Microgreens
Brimming with nutrients, microgreens boast up to five times more vitamins and minerals than their mature counterparts. The level of nutrients they possess is directly proportional to how much light they receive during their growth. This only underscores the importance of providing them with an optimum growing environment.
Microgreens require minimal care compared to other plants. If provided with the right necessities, they grow quickly, and you can start to harvest as soon as their first leaves appear, which usually happens within one to three weeks of planting.
Essential Tools and Materials for Microgreen Growing at Home
Starting a microgreen garden at home requires minimal tools and materials, most of which are standard items for plant care and are easily accessible.
You will need: Seed trays, Quality potting mix or organic soil, Spray bottle for watering, A source of light, preferably natural if possible and High-quality seeds.
When it comes to seeds, choose ones that are certified organic, non-GMO, and not treated with fungicides. This ensures not only a safe and healthy yield but also a higher success rate in germination.
The Microgreen Cultivation Process
To successfully cultivate microgreens at home, follow these general steps:
Preparation: First, prepare your seed tray with your chosen medium. This could be a specially designed microgreen mat or high-quality potting soil. Pre-moisten the medium before sprinkling your seeds.
Sowing: Sprinkle your chosen seeds uniformly over the surface of the medium. Aim for an even distribution but don’t obsess about precision.
Covering: After sowing, lightly press the seeds into the soil with your hand or a small board to ensure good contact with the soil. Cover your seeds with a thin coating of soil or place a grow tray or blackout dome over the planted tray.
Watering: Using a spray bottle, lightly spray the sown seeds. Be aware that overwatering could lead to the growth of mold and fungus.
Position: Place the tray in a well-lit area that is free from extreme temperature fluctuations. A windowsill or countertop is usually sufficient for this purpose.
The Care for Microgreens
Microgreens that are well cared for will produce a higher yield. Their growth and survival depend on watering, the amount of light they receive, and the temperature and ventilation conditions.
Watering: Microgreens don’t require much water. Misting the soil surface regularly is generally enough, keeping in mind that overwatering can contribute to the development of disease.
Light and temperature: Most microgreens prefer cool conditions with plenty of indirect light. The temperature should be maintained around 60 to 70°F (15-20°C).
Ventilation: Good air circulation helps prevent disease. It’s advisable to place a fan nearby to gently blow over the seedlings to help strengthen stalks and increase air exchange rates.
Harvesting Your Microgreens
Judging when to harvest your microgreens is mostly reliant on visual cues. Most varieties are ready to harvest in 10 to 20 days after planting when they reach 1 to 2 inches in height and produce their first set of true leaves.
To harvest, simply cut the stem above the soil line. It’s essential that this is done immediately before eating or cooking to maintain maximum freshness and nutrient content.
Troubleshooting Common Issues
Like with any garden, you might experience a few issues with your microgreens along the way. However, with a little knowledge and patience, they’re easy to resolve.
Weak or leggy seedlings: This could indicate that your microgreens aren’t getting enough light. Try moving them closer to the light source or increasing the hours of light exposure.
Stunted growth: Microgreens that aren’t growing could be due to a too cold or too hot environment. Adjust your thermostat or consider a heating mat if the problem persists.
Moldy seedlings: Overwatering, lack of air circulation, or too much humidity usually causes mold. Ensure you’re not overwatering your microgreens, improve ventilation, or use a dehumidifier to manage this.
Becoming adept at cultivating microgreens at home takes time and practice. But, with patience and persistence, you will surely reap the rewards of this fascinating art.
