Orchiata bark from Daltons Orchiata NZ is a heat-treated Pinus radiata pine bark medium for orchid cultivation, imported from New Zealand. It is supplied in 8.5 liter bags with four grade sizes: 3-6mm (fine), 9-12mm, 12-18mm (medium), and 18-25mm (coarse). The kiln-firing process removes tannins, pathogens, and sugars, yielding a sterile, pH-neutral substrate with low dust and consistent sizing. This ensures balanced moisture retention, excellent drainage, and aeration to support healthy root development and reduce rot risk. Finer grades suit seedlings; coarser ones fit mature plants. Specify required grade when ordering.
