Why Bio Leaf Orchid Mix Stands Out

- A chunky, fast-draining structure
- Superb aeration and reduced risk of "wet feet"
- Protection against over-watering
- A long lifespan - often lasting 3 years or more before needing repotting

What's Inside

Bioactive Organic Nutrients
A proprietary blend of calcium, silica, and organic compounds provides slow- and fast-release supplementation to strengthen roots, reduce transplant shock, and support recovery - without adding fertiliser you can't control.

Premium Orchid Bark

- NZ-sourced, export-quality
- Clean, sterile, and slow to break down
- Enhances drainage and aeration
- Holds moisture for steady release

Pumice

- Lightweight volcanic rock
- Adds airflow and prevents compaction
- Holds moisture longer than bark without waterlogging

Fern Fibre

- Airy, long-lasting, and moisture-balancing
- Ideal for epiphytes
- Distributes water evenly around roots

Hardwood Charcoal

- Adds drainage and improves airflow
- Naturally antifungal and antibacterial
- Helps balance mix pH
- Bio Leaf avoids activated charcoal to prevent nutrient loss
