CANNA Coco Coarse – Airy Peat-Free Coco for Monstera & Aroids

Type: Buffered and lightly pre-fertilised
CANNA Coco Coarse comes buffered, with a light starter charge to ease young plants in. That's a gentle head start, not a full feed, so start your own feeding after the first week or two.

CANNA's Most Open, Airy Coco Yet

Most airy mixes rely on perlite or clay pebbles to keep coco open. CANNA Coco Coarse does it on its own, blending coarse coco fibre with rice husk to create an open, structure-stable substrate that holds far more air than standard coco and drains quickly. It keeps that structure for the whole life of the plant, so roots stay oxygenated even with frequent watering.

Why It Works

• Maximum air at the roots: the coarse structure keeps oxygen flowing, protecting against soggy roots and root rot.
• Fast drainage: excess water clears quickly, so pots never sit waterlogged.
• Doesn't compact: the rice husk and coarse fibre hold their shape over time.
• No extra ingredients needed: airy enough to use straight from the bag, with no perlite or pebbles required.
• Peat-free and sustainable: made from renewable coco and rice husk.
• Genuine CANNA quality: buffered to commercial standards and designed to pair with the CANNA coco feed range.

For Houseplant Lovers

Chunky, airy, free-draining coco is exactly what Monstera, Alocasia, Anthurium and climbing Philodendron want. These plants grow up trees in the wild, and their roots need air as much as water. CANNA Coco Coarse gives you that chunky aroid structure in a single bag, without having to mix in pebbles. It's also a great pick for anyone who tends to overwater.

Prefer a mix with clay pebbles? Our LECA & Coco 60/40 mixes do a similar job. Growing moisture-lovers like Calathea or ferns? A finer 70/30 coco and perlite mix will hold water more evenly for them.

For Growers

Built for fast-growing plants with high oxygen demand, CANNA Coco Coarse suits hand watering, drip irrigation and gravity-fed systems. The open structure supports frequent, heavy feeding without waterlogging, and roots branch hard into the air-filled space. Pair it with CANNA Coco A&B, formulated specifically for CANNA coco. You'll get 10% off when you buy the two together.
