Genuine CANNA coco, hand-blended in-house with 30% PLAN!T perlite, for houseplants that love steady moisture without ever sitting wet.

We take authentic CANNA coco substrate and mix it ourselves with premium PLAN!T horticultural perlite, giving you CANNA quality in a ready-to-pot houseplant mix you won't find off the shelf.

Choose Your Base

Coco Professional Plus 70/30: CANNA's pre-treated, pre-washed premium coco, for stable pH and low EC straight out of the bag. The plug-and-play choice.
Coco Natural 70/30: CANNA's natural coco base, for anyone who likes to fine-tune their own feeding.

Why a 70/30 Mix?

Even moisture: 70% coco holds water evenly through the pot, so roots never swing from soaked to bone dry.
Air at the roots: 30% perlite keeps pockets of oxygen open even when fully watered, protecting against root rot.
Gnat-resistant: clean coco gives fungus gnats far less to breed in than standard peat compost.
Unfertilised blank canvas: no pre-mixed fertiliser, so no risk of fertiliser burn, and full control over what you feed.

Perfect For

Calathea, Maranta, Stromanthe and Ctenanthe: the "drama queens" that need constant, even moisture
Pothos, Scindapsus, heartleaf Philodendron and Syngonium
Ferns, Fittonia and Peperomia
Cuttings and propagation: rooting nodes and fresh cuttings

Potting a Monstera, Alocasia or Anthurium? These chunky-rooted climbers want even more air around their roots. Our CANNA Coco Pebble 60/40, with clay pebbles through the coco, is the better match.

Before You Buy

This is an unfertilised base, so start a liquid feed from the first watering. Being genuine CANNA coco, the natural pairing is CANNA Coco A&B, formulated specifically for coco.
