Complete Guide to Growing and Caring for Microgreens


Microgreens, the young and tender seedlings of edible vegetables and herbs, have gained immense popularity for their nutritional value, vibrant colors, and delicate flavors. Whether you have a large garden or limited space, growing microgreens is a fantastic way to enjoy fresh greens all year round. This comprehensive guide will walk you through the process of growing and caring for microgreens, from when to start, preparation, growing guides, to frequently asked questions. Let’s embark on a journey to cultivate these miniature powerhouses of nutrition.

When to Grow Microgreens

Timing: Microgreens can be grown indoors throughout the year, making them an excellent choice for year-round cultivation.

Consideration: Choose the appropriate time to sow based on the desired growth cycle and environmental conditions for the specific microgreen variety.

Preparing Before Growing Microgreens:

Selecting Seeds: Opt for high-quality, organic seeds specifically labeled for microgreen production. Popular choices include lettuce, kale, arugula, radish, and basil.

Choosing Growing Containers: Use shallow containers or trays with drainage holes. Seed trays, nursery flats, or even recycled containers like shallow food containers work well.

Preparing Growing Medium: Microgreens thrive in soilless growing mediums such as potting mix, coconut coir, or vermiculite. Ensure the medium is sterilized and free from contaminants.

Full Growing Guides for Microgreens:

Sowing Seeds: Fill the growing container with the chosen growing medium. Spread the seeds evenly and densely across the surface, pressing them gently into the medium.

Watering: Mist the seeds with water or use a gentle spray to keep the growing medium moist. Avoid waterlogging, which may cause rotting.

Light and Temperature: Place the trays in a well-lit area or under grow lights, ensuring they receive 12-16 hours of light daily. Maintain a temperature between 60-75°F (15-24°C).

Covering and Germination: Optionally, cover the seeds with another tray or plastic wrap to create a mini greenhouse effect, promoting germination. Remove the cover once the seeds sprout.

Maintenance: Continue to mist the microgreens as needed to maintain moisture levels. Monitor for signs of disease, and remove any damaged or discolored shoots.

Harvesting: Microgreens are typically ready for harvest within 7-14 days. Use scissors to snip the stems just above the soil line. Rinse and enjoy!

Q1: What are the best microgreen varieties to grow?

A1: Some popular microgreen varieties include broccoli, radish, kale, arugula, sunflower, pea shoots, and basil. However, the best varieties to grow depend on personal preference and intended use.

Q2: How do I store harvested microgreens?

A2: It’s best to consume microgreens immediately after harvesting for maximum freshness and nutritional value. If you need to store them, place them in a sealed container or a plastic bag with a paper towel to absorb excess moisture. Store them in the refrigerator and use within a few days.

Q3: Can I reuse the growing medium for subsequent batches of microgreens?

A3: It is not recommended to reuse the growing medium for multiple batches of microgreens, as it may harbor diseases or pests. It’s best to start with fresh, sterile growing medium for each new batch.

Q4: How often should I water my microgreens?

A4: Microgreens need consistent moisture, but it’s important not to overwater them. Check the moisture level of the growing medium daily and mist the microgreens as needed to keep the medium slightly moist. Avoid waterlogging, as it can lead to fungal issues.

Q5: Do microgreens require fertilization?

A5: Microgreens typically don’t require additional fertilization during their short growing period. The nutrients in the seeds and the initial growing medium are usually sufficient. However, if you notice slow growth or pale leaves, you can use a diluted, organic liquid fertilizer specifically formulated for seedlings.

Remember, these answers provide general guidelines, and it’s essential to adjust your approach based on the specific microgreen variety and your growing conditions. Happy growing!
