How do I switch from peat-based compost to cocopeat?

A peat-free switch is a growing-system change, not just a bag substitution.

THE COCOPEAT CONNECTION

Why the root zone matters

Coir blends can differ from peat blends in wetting, nutrient supply and physical structure.

01 / OBSERVE

Three checks before you change anything

  1. List the current mix ingredients and fertiliser charge
  2. Trial the replacement with the same crop
  3. Track irrigation and feeding adjustments separately

02 / NARROW IT DOWN

Where are you in the switch?

Choose the closest observation for a suggested next check.

Planning a trial

Keep a small reference group in the existing mix.

Plants already moved

Compare moisture and nutrition records before repeating the old schedule.

Only buying on price

Compare delivered usable volume and growing performance as well.

03 / TAKE THE NEXT STEP

Leave with something useful

Set success criteria for the trial before ordering the full replacement.

Keep in mind

Do not claim every coir blend performs identically to peat.
