The History of Organic Microgreen Farming
Microgreens have existed for centuries, but organically growing them is relatively new. The first known mention of microgreens was in the writings of Chinese herbalist Shennong, who lived in the 28th century B.C. Shennong wrote about the health benefits of microgreens, and he recommended them to improve digestion and boost the immune system.
There is no direct mention of microgreens in the Shennong Bencao Jing, but there are references to sprouts and young plants. For example, the book mentions using Brassica juncea sprouts (known as kai-lan in Chinese) for their medicinal properties.
It is possible that Shennong was aware of the health benefits of microgreens and included them in his herbal remedies. However, there is no definitive proof of this.
There has been a growing interest in microgreens in China in recent years. They are now being cultivated and consumed in many parts of the country.
The history of organic farming is a tale of transformation, a shift from traditional agricultural practices towards a more sustainable and holistic approach. The story begins in the early 20th century, but its roots go back much further.
The term “organic farming” was first coined by Lord Northbourne in his book “Look to the Land,” published in 1940. However, we can trace the principles of organic farming back to traditional farming practices that existed before the advent of synthetic fertilizers and pesticides. These practices emphasized the importance of soil health, crop rotation, and biodiversity.
The modern organic farming movement gained momentum in the mid-20th century as a response to the industrialization of agriculture. Pioneers like Sir Albert Howard, Lady Eve Balfour, and J.I. Rodale began to promote organic methods to improve soil health and produce healthier, more nutritious food.
Organic farming gained further traction in the 1970s and 1980s as environmental concerns became more prominent. The harmful effects of synthetic pesticides and fertilizers on the environment and human health became increasingly apparent, leading to a growing demand for organic produce.
In the 1980s, microgreens began to gain popularity in the United States, partly due to the growing interest in healthy food and the increasing availability of organic produce. Microgreens are popular in salads, sandwiches, smoothies, juices, and other beverages.
Organic microgreen farming is a method of growing microgreens that uses no synthetic chemicals or pesticides. This kind of production is becoming increasingly popular thanks to the health benefits of microgreens and a growing demand for organic foodstuffs.
The turn of the 21st century saw organic farming becoming more mainstream, with more farmers adopting organic methods and consumers choosing organic products. Today, organic farming is recognized worldwide for its environmental and health benefits, and its principles are applied to various forms of agriculture, including the cultivation of microgreens.
The history of organic farming is not just a chronicle of agricultural practices but a testament to our evolving understanding of the intricate relationships between soil, plants, and human health. It’s a journey towards sustainability, and it’s a journey that continues today.

The Importance of Seed Selection for Organic Microgreen Farming
Seed selection is a critical step in organic microgreen farming. The quality of the seeds you choose directly influences the success of your crop, affecting everything from germination rates to the nutritional content of the mature microgreens. The selection of seeds to grow organically microgreens should take into account the following key factors:
Organic Certification
To ensure your microgreens are genuinely organic, starting with certified organic seeds is essential. These seeds are produced without synthetic pesticides and fertilizers and are not genetically modified. Seeds can carry pathogens like Salmonella or E. coli., even if certified organic. If you are growing sesame seeds, this is even more critical (Food Allergies: What You Need to Know | FDA).
The Food Allergy Safety, Treatment, Education, and Research (FASTER) Act 2021 added sesame to the list of major food allergens. The change took effect on January 1, 2023.
Source seeds from reputable suppliers and request a certificate of analysis (CoA). Find the best seed sources on the Seed Resources page.
Variety
Different microgreen varieties have different growth rates, flavors, and nutritional profiles. Choose a variety of seeds to provide a diverse range of microgreens for your customers or your consumption.
Germination Rate
The germination rate of a seed batch determines how many seeds will likely sprout. High germination rates (usually above 90%) are desirable as they indicate good seed quality and result in a fuller, more productive crop.
Disease Resistance
Seeds resistant to common diseases can save you much trouble down the line. It is especially important in organic farming, where you don’t use synthetic fungicides and pesticides.
Supplier Reputation
Purchase your seeds from a reputable supplier. Reliable suppliers provide high-quality seeds and can offer valuable advice on how to grow them successfully.
Seed Size
Larger seeds can be easier to handle and may have higher energy reserves, leading to more vigorous seedlings. However, smaller seeds often cost less and can produce a denser crop.
Remember, successful organic microgreen farming starts with careful seed selection. Choosing high-quality, certified organic seeds sets the stage for a healthy, productive crop packed with nutritional value. Request a Certificate of Analysis.

| Temperature and Humidity Control | Microgreens prefer a temperature range of 60-70°F (15-21°C) and relative humidity of 40-60%. Monitor these conditions closely to prevent the growth of mold and other diseases. | |
| Pest Management | In organic farming, synthetic pesticides are off-limits. Use natural methods like introducing beneficial insects, using organic sprays, or employing physical barriers to manage pests. | |
| Harvesting | Tools or equipment can introduce physical hazards. | Use well-maintained tools and equipment, and inspect for physical hazards. Your microgreens should be harvested once they’ve developed some leaves. Use a sharp knife or shears to cut the stems over the soil line. |
| Rotation and Diversity | Growing a variety of microgreens provides a diverse product and helps break pest and disease cycles. |
By following these best practices, you can grow healthy, nutritious microgreens while respecting the environment and promoting sustainability.
How to Harvest and Store Microgreens
Harvesting and storing microgreens properly is crucial to maintaining their freshness, nutritional value, and flavor. Here’s a step-by-step guide to help you through the process:
Harvesting
Timing
Microgreens are typically ready to harvest 7-14 days after planting when they develop their first set of true leaves. You must harvest before the second set of leaves (adult leaves) start to grow.
Tools
To ensure the cut is clean and minimize any harm to the plant, use a sharp pair of scissors or knives.
Method
Cut the microgreens just above the soil line. Be gentle to avoid bruising the delicate leaves.
Hygiene
Ensure your hands and tools are clean to prevent the spread of disease.
Storing Microgreens
Cleaning
Rinse the harvested microgreens gently under cold water to remove any soil particles. It would be best not to hurt the leaves and stems.
Drying
Wash the microgreens with a clean towel or use a lettuce spinner to eliminate too much water. They need to be thoroughly dry before storage to prevent decay.
Packaging
Store the microgreens in a clean, airtight container. You can use a plastic bag or a container with a lid. Some prefer to line the container with a paper towel to absorb excess moisture.
Refrigeration
Place the container in the refrigerator. You can store most microgreens at four °C (39°F) for 5-7 days. Some hardier varieties can last up to two weeks.
Usage
Use your stored microgreens immediately. The longer they’re stored, the more their nutritional value decreases.
Remember, the key to harvesting and storing microgreens is handling them gently and keeping them cool and dry to ensure they remain fresh and nutritious for as long as possible.
How to Market and Sell Organic Microgreens
Marketing and selling microgreens effectively require a strategic approach. Here are some critical steps to help you successfully market and sell your organic microgreens:
| Identify Your Target Market | Understand who your potential customers are. These could be local restaurants, farmers’ markets, grocery stores, or health-conscious consumers in your community. You will be better able to craft a marketing campaign that is successful in reaching them if you know your target market. |
| Quality and Variety | Ensure your microgreens are of high quality. Offer a variety of microgreens to cater to different tastes and culinary needs. Unique or exotic varieties can often fetch a higher price. |
| Branding and Packaging | Create a strong brand for your microgreens business. Your branding should communicate your product’s quality, freshness, and organic nature. Invest in attractive, eco-friendly packaging that keeps your microgreens fresh and showcases their vibrant colors. |
| Online Presence | Establish an online presence through a business website and social media platforms. Share engaging content like recipes, health benefits of microgreens, and behind-the-scenes glimpses of your farming process. |
| Direct Sales | Consider selling directly to consumers through farmers’ markets or a CSA (Community Supported Agriculture) model. Direct sales often yield higher profits and allow you to build customer relationships. |
| Networking | Build relationships with local chefs, nutritionists, and food bloggers who can help promote your microgreens. Attend local food and farming events to network and showcase your products. |
