Is That White Fluffy Stuff on My Microgreens Mould?

Understanding Root Fur in Microgreens

Many growers often mistake the white fluffy stuff on their microgreens for mould. However, these are usually small fuzzy root hairs, known as root fur, which are beneficial and completely normal – your greens need this to enable them to grow!

Why it matters:

  • Root fur increases the surface area for water uptake, promoting healthy plant growth.
  • Differentiating between root fur and mould ensures proper care and maintenance of your microgreens.

The bigger picture:

Mould thrives in dark, moist environments and can look similar to root fur. While root fur appears as a dense, white fuzz around the base of the seedlings, mould looks like long, stringy spiderwebs creeping across the soil surface. Understanding the difference is crucial for maintaining the health of your microgreens.

In Between the Lines:

  • Root Fur: Indicates healthy growth and efficient water uptake.
  • Mould: Harmful fungus that needs to be addressed promptly to avoid damaging your plants.

 The Quick Facts:

  • Root Fur: Beneficial, white fuzzy root hairs for water uptake.
  • Mould Appearance: Long, stringy spiderweb-like growth on the soil surface.
  • Combating Mould:
    • Use 3-6% Hydrogen Peroxide (H2O2) solution.
    • Mix a few mL of H2O2 with water in a spray bottle.
    • Spray affected areas daily until mould disappears.
    • Alternative remedies: baking soda solution, vinegar or lemon juice mixed with water.

What's Next: Expose your microgreens to light and ensure good air circulation to prevent mould growth. If the greens are ready for light, uncover them and place them beside a sunny window.
