Approximately 5L of Collectors Blend Orchiata Bark Power 9–12mm, made from aged Pinus radiata bark, delivers excellent drainage and airflow for healthy orchid roots. With a medium-coarse 9–12mm particle size, it’s ideal for mature epiphytic orchids such as Dendrobium and Oncidium, providing structural stability while supporting moisture control. Naturally processed and long-lasting, this substrate promotes vigorous growth and consistent flowering in a wide range of orchid species.
Why Orchiata?
Produced through a certified 10-step production process in New Zealand, Orchiata bark is screened, aged, and buffered for superior consistency and quality. Each batch is tested to ensure freedom from pathogens and optimal growing conditions. Learn more here.
Note: Some surface fungi may be visible — this is a natural occurrence and does not harm plants. Read more in Fungal Appearances on Orchiata.
