Starting Microgreens with Seeds: A Comprehensive Guide.
Microgreens comprise the seedlings of vegetables, herbs and other plants that can be harvested and eaten when they’re still very small. They’ve gained attention in recent years for their tremendously high nutrient content and ease of cultivation. Though small in size, their nutritional profile is quite impressive. They often contain higher nutrient levels than more mature vegetable greens, enriching them with vitamins, minerals, and antioxidants.
Choosing Your Microgreens Seeds
The first step in starting microgreens is selecting the right seeds. There is no one-size-fits-all approach to this; instead, the choice depends on your preference in terms of taste, nutritional value, and the ease of growth. Some common choices include radishes, broccoli, lettuce, kale, dill, basil, mustard, beet, and chia. Each has its unique flavor, color, texture, and growth rate.
Where can you get the seeds? Well, they’re available in many garden centers and online platforms. Make sure you purchase from reputable sellers to guarantee you get high-quality, non-treated seeds. Non-treated seeds ensure that your microgreens will be free from harmful chemicals.
Preparing Your Growing Trays and Soil
After obtaining your seeds, the next step is to prepare your growing medium and trays. Microgreens don’t require a lot of space to grow. A shallow tray, such as a 1020 tray, usually works best. Ensure the trays have proper drainage as microgreens don’t thrive well in waterlogged conditions.
One crucial aspect about microgreens is that they need nutrient-rich soil. Using high-quality organic potting soil would be more appropriate. Fill the trays with about 1-2 inches of this soil, then gently pat it down to create a firm but not overly compacted surface.
Sowing the Seeds
For effective growth, it is essential to sow the seeds correctly. Distribute the seeds evenly over the surface of the soil. If the seeds are too close to each other, it could lead to the molding of seedlings and poor airflow. Too much spacing, on the other hand, leads to underutilization of space and resources.
Watering the Seeds
Water your seeds lightly using a spray bottle or a light sprinkler, ensuring the soil remains consistently moist but not drenched. Most seeds need a sufficient amount of water to germinate correctly.
Cover your trays after watering to maintain a high humidity environment around the seeds. If you are using a 1020 tray, you can use a cover or an inverted tray for this.
Providing Correct Lighting Conditions
Proper lighting is crucial for your microgreens’ growth. If you are growing them outdoors, natural light will typically suffice. For indoor planting, you may require artificial grow lights.
LED grow lights are considered the best. They provide the full spectrum of light, resembling the sun’s natural light, are energy-efficient and produce less heat, reducing the risk of crops wilting.
Maintaining Optimal Temperature and Humidity
The temperature for germination varies with different microgreens, but most prefer the range of 68-75 °F. Make sure to always check the instructions on the seed packets.
Humidity is essential during the early stages of germination, hence the covering of trays after planting. When the seedlings start appearing, uncover the trays to provide them with the necessary air circulation.
Caring for Your Microgreens
Now that you’ve planted your microgreens, it’s just a matter of waiting and caring for them until harvest.
Ensure they get six to eight hours of light daily. About four days after planting, you can start watering them gently from the bottom to avoid disturbing the seedlings.
Harvesting Your Microgreens
Microgreens are typically ready to harvest 7-21 days after planting, though the time varies with each variety. A general indication that they are ready for harvest is when their first true leaves appear.
To harvest, use a clean, sharp knife or scissors to cut the plants just above the soil line. Rinely, and they’re ready to be served.
Microgreens are a nutrient-packed addition to any meal, adding color, crunch, and a unique taste to salads, sandwiches, and many more dishes. Starting microgreens with seeds is rewarding, relatively easy, and a great way to immerse yourself in the world of vegetable gardening, even with limited space.
