TNZ Grow


Taken almost exclusively from milled-for-timber Pinus Radiata trees, all our bark is a natural and environmentally friendly product.


Located in Southland, New Zealand, our own company proudly owns and manages our peat resource. This enables us to select the right grade of peat for each customer's requirements.

Custom Mixes

All of our potting and growing media mixes are peat and bark-based and custom manufactured to each customer's requirements.
