• Orchid Bark Coarse may be combined with a range of other materials to provide orchid composts with the desired degree of porosity. • A typical mix would be 5 parts Orchid Bark Coarse to 1 part crushed charcoal to 2 parts medium perlite, but other ingredients such as coarse grit and fibrous coir can equally successfully be incorporated. Lime should be added to raise the pH, typically at 2.5kg/m3, but the exact requirement will depend on the other ingredients in the mix.
Please contact Melcourt for more details.
For a smaller chip use Orchid Bark Medium.
