How to Grow Broccoli Microgreens Indoors This Winter

If you’ve never grown microgreens before, broccoli is the perfect place to start - especially in winter when outdoor gardening slows down. They’re quick, clean, and can be harvested in as little as 7–10 days.


What You’ll Need

  • High-quality Broccoli seeds
  • Growing medium: coconut coir, hemp mat or fine soil
  • Shallow tray with drainage holes
  • Spray bottle or watering can
  • Natural light or grow light


Step-by-Step Guide

  1. Prepare your tray: Fill with moistened growing medium.
  2. Sow seeds evenly across the surface.
  3. Cover to block out light and retain humidity.
  4. Wait 2–3 days for germination, then move to a well-lit spot.
  5. Water gently, ideally from the bottom to avoid mould.
  6. Harvest when the first true leaves appear - around day 10.

Tips for Success

  • Keep the environment warm but not too humid.
  • Ensure good airflow to prevent mould.
  • Avoid overwatering - less is more.


Conclusion

It’s that easy! No garden space required - just a sunny windowsill and a bit of daily care.
