How to Grow Radish Microgreens

Follow this simple step-by-step guide to grow your own radish microgreens: 

Materials Needed

  • Seeds: Look for high-quality radish seeds from trusted sources like Ausallium.
  • Growing Medium: Choose a well-draining option like potting soil, coconut coir or hemp mats. 
  • Tray or Container: Ensure it has proper drainage.
  • Light Source: Use natural sunlight or grow lights.
  • Water: Maintain a spray bottle or watering can for consistent hydration.


Steps to Grow

Step 1: Calculate Seed Requirements

Determine the amount of seed needed based on the germination rate. A higher germination rate results in better yields. Test your seeds or refer to the germination rate on the seed packet. Ensure your seeds have a minimum germination standard of 85% for optimal results.


Step 2: Choose your Growing Medium and Prepare your Tray 

The right growing medium is key to healthy microgreens. Radish microgreens thrive in well-draining mediums that retain moisture without becoming soggy. Using a premium mix ensures proper moisture retention and nutrient availability. Fill your tray with your chosen medium and lightly water. 


Step 3: Prepare and Plant the Seeds

Evenly sprinkle the seeds across the surface, ensuring good contact by gently pressing them down. Lightly water then cover the tray with a lid or cloth and place it in a dark, warm location for 3-4 days to promote germination.


Step 4: Water Consistently

After the seeds germinate, water from below to maintain moisture and reduce the risk of mould. Use a bottom tray to water and ensure proper airflow to prevent excess moisture buildup. Water daily or as needed to keep the medium moist but not soggy.


Step 5: Provide Light and Warmth

Place the tray in a bright location with 6-8 hours of daily sunlight or under grow lights. Maintain a temperature between 21-24°C and humidity levels of 40-60%. Rotate the tray regularly for even growth.


Step 6: Harvest

In 7-10 days, when the microgreens are 2-3 inches tall and have developed their first true leaves, they are ready to harvest. Use scissors to cut the microgreens just above the soil line. Store harvested greens in a dry container with a paper towel to extend freshness.

Tips to Avoid Common Growing Issues

Even though radish microgreens are relatively easy to grow, you might encounter some challenges. Here are troubleshooting tips:

  • Mould Growth: Ensure proper airflow and avoid overwatering. Use a fan to increase circulation if needed.
  • Uneven Growth:  Spread seeds evenly and rotate trays to ensure all sides receive equal light.
  • Yellow Leaves: Increase light exposure and check for overwatering or nutrient deficiencies.

Keep your growing environment clean and monitor humidity levels to prevent mould or disease. 


Storing Radish Seeds

Proper seed storage is essential to ensure their longevity and viability. Follow these tips:

  1. Cool and Dry: Store seeds in an airtight container in a cool, dark place.
  2. Refrigeration: Can extend seed viability and maintain freshness.
  3. Labelling: Clearly label containers with the seed type and storage date.
  4. Rotation: Use older seeds first to maintain freshness.
