How to Grow Radish Microgreens

Radish microgreens are quick and easy to grow. Unlike other microgreens, radish seeds do not need to be soaked before sprouting.


  • Spread the radish seeds onto a damp growing medium. 
  • Mist the seeds with water.
  • Cover the seeds and keep them away from light for 3 - 5 days. 
  • This is the blackout period referred to on the seed packet. 
  • Keep the seeds moist by misting them with water from a spray bottle. 
  • Maintain an average room temperature.

  • Check microgreens daily and mist as needed to keep them moist.
  • Once the radish seeds have sprouted, remove the cover and expose the seedlings to direct light.
  • The light during this growth period is essential for radish microgreens. The bright green leaves that develop during the photosynthesis process are full of nutrients.
  • Continue keeping the seeds moist until they’re ready to harvest.

When and How to Harvest Radish Microgreens

In 5-12 days, when seedlings are about 2 inches tall, they will be ready to harvest. The seed leaves (cotyledons) will be fully grown. 


Use scissors to cut the radish greens just above the soil. 


Then rinse in cool water. 


Use radish microgreens immediately or place in the fridge and consume within a few days.
