Orchiata Power 9–12 mm · 5 L
Orchiata is recognised as one of the leading substrates for orchids and is made in New Zealand from natural, aged Pinus radiata bark. The 9–12 mm Power grade suits young and mature orchids with medium-sized roots, providing a stable, open structure that supports a reliable balance of moisture and airflow and helps extend the interval between repotting.

Composition & profile
Stable bark with a uniform particle size
The bark undergoes a controlled natural ageing process rather than composting. This removes the water-repellent outer layer while keeping the core of each piece hard and structurally stable.
- Power · No.5: A uniform 9–12 mm grade for orchids with medium-sized roots.
- Natural aged bark: Solid pieces resist chipping and do not compost quickly inside the pot.
- Open outer surface: Holds water and nutrients while the hard inner structure maintains air spaces.
- Added dolomite: Sets the initial pH and provides a starter source of calcium and magnesium.
Longer-lasting structure
The hard bark pieces retain their shape and help reduce how often repotting is needed.
Air and moisture balance
The Power grade provides 49–53% AFP and 56.8% WHC, keeping roots aerated without abrupt moisture loss.
Consistent rewetting
The processed surface rewets effectively and supports a more reliable wet-and-dry cycle.
Repotting steps
For orchids with medium-sized roots
Suitable for Phalaenopsis, Oncidium, Odontoglossum, Dendrobium and Paphiopedilum, as well as other orchids matched to a 9–12 mm grade.
- Phalaenopsis
- Oncidium
- Odontoglossum
- Dendrobium
- Paphiopedilum
- Young & mature orchids
Use an orchid pot with adequate drainage holes and avoid a pot that is excessively wider than the root system.
Place a thin layer of Orchiata in the bottom and keep the roots below the rim of the pot.
Fill the gaps without firm pressure and tap the sides lightly so the bark settles evenly.
Wet the Orchiata thoroughly after repotting and allow all excess water to drain away.
No washing or soaking before use
Use Orchiata straight from the pack. Washing is unnecessary and removes the dolomite added during production.

Frequently asked questions
Quick answers about choosing the grade, using, watering and storing Orchiata.
01What does Orchiata Power contain?
Its base is natural, aged New Zealand Pinus radiata bark graded into 9–12 mm pieces. Dolomite is added during production to set the initial pH and provide calcium and magnesium.
02Which orchids is it suitable for?
The 9–12 mm Power grade suits young and mature orchids with medium-sized roots, including Phalaenopsis, Oncidium, Odontoglossum, Dendrobium and Paphiopedilum.
03Does it need washing or soaking before use?
No. Use it straight from the pack. Washing removes the added dolomite and provides no benefit to the product.
04How do I know when to water again?
Check the weight of the pot and the moisture inside the substrate. In small pots, allow roughly the top 2–3 cm to dry; in larger pots, allow the top 4–5 cm to dry. Frequency changes with the orchid, pot and season.
05Does it need fertiliser?
Yes. Dolomite initially provides calcium and magnesium, but it does not replace a complete feed. Use a fertiliser suitable for orchids and follow its label directions.
06What is the white powder or fine grey-white coating?
White powder is usually dolomite and should not be washed away. A fine fungal coating may also appear in warm, damp conditions; it does not harm the orchid. Aerate the material and keep it cooler and drier.
