How to Grow Broccoli Sprouts

Growing your own broccoli sprouts indoors is easy. Here's how to do it.


  • Step 1: Allow the seeds 24 to 36 hours to germinate at 70 to 78 degrees Fahrenheit. If the temperature is below 60 degrees or above 90 degrees, the seeds will take longer to germinate and grow.
  • Step 2: Wait for 3 to 5 days after germination for your plants to grow. Then clip the sprouts with kitchen scissors and sprinkle them over salads, put them on sandwiches, or eat them plain.
  • FACT: Baby broccoli plants contain up to 50 times more sulforaphane, an anti-cancer chemical, than broccoli heads.
  • Step 3: Place a clear, ventilated lid over each container and set the containers under a fluorescent light or near a window inside your house. Avoid direct sunlight, which may be too warm for germination.
  • Step 4: Cut sheets of white paper towel to fit in the bottoms of your containers. Then wet the sheets and put them inside the containers. Sprinkle 1 tablespoon of seed over each paper towel.
  • Step 5: Soak your broccoli seeds for 20 minutes in the same 10 percent bleach solution you used for the containers. Then place them in a wire mesh strainer and rinse them under cool running water.
  • TIP: Use broccoli seeds that haven't been treated with insecticides or fungicides.
  • Step 6: Clean and sanitize your containers by soaking them in a solution of one part bleach to nine parts water for 20 minutes. Then rinse the containers with cool water and allow them to dry.
