Roots & watering
Roots look brown
Root colour is a clue, not a diagnosis. Compare texture and plant performance with a healthy plant before assuming every tan root is rotten.

What is the white growth on my cocopeat surface?
White material could be fungal growth, salt residue or another deposit; inspect before treating.

Why the root zone matters
The substrate surface experiences wetting, drying and organic-material exposure unlike the deeper root zone.
01 / OBSERVE
Three checks before you change anything
- Photograph texture and distribution
- Check for recent fertiliser deposits or spills
- Inspect roots and plant health
02 / NARROW IT DOWN
What does it resemble?
Choose the closest observation for a suggested next check.
Dry crust after irrigation
Review water and feed residues and confirm EC.
Fuzzy spreading growth
Seek identification and review wetness and organic debris.
Plants also declining
Arrange prompt root and substrate assessment.
03 / TAKE THE NEXT STEP
Leave with something useful
Record whether the material changes after drying and whether plants are affected.
Keep in mind
Do not identify a pathogen from surface colour alone.
