Orchiata #9

While the #9 grade is specifically sized for seedlings and miniature orchids due to its 6-9mm particle size, it can be used for adult orchids that require very fine, moisture-retentive media. However, for larger, mature orchids with thicker root systems, you may want to consider a coarser grade to ensure adequate airflow.

No, Orchiata is ready to use straight from the bag. It is processed to be clean and free of pathogens, so you can pot your plants immediately without any additional preparation.

Orchiata is made from Pinus radiata bark, which is significantly more durable than standard fir bark. While typical potting media often break down within 1-2 years, this substrate can maintain its structure and aeration for up to 10 years, meaning you will need to repot your orchids much less frequently.

The #9 grade is designed to balance moisture retention with necessary drainage. Because the particles are uniform and small, they hold water well, but the inherent structure of the Pinus radiata bark prevents the mix from becoming soggy, provided your pot has adequate drainage holes.

You certainly can, though Orchiata is formulated to be a complete, high-performance medium on its own. If you prefer to add amendments for extra drainage or microbial health, this bark provides a stable, long-lasting base that will hold those additions in place effectively.
