THE COCOPEAT CONNECTION

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

  1. Photograph texture and distribution
  2. Check for recent fertiliser deposits or spills
  3. 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.
