Our Process 

Consistent quality with every order.

Consistent, High-Quality Raw Materials

  • Our Horticultural Bark exclusively uses 100% Pinus Radiata bark, with no substitutes, and long-term supply contracts for this specific bark guarantees consistent availability throughout the year. 

  • Additional media components, such as Peat, Coir, Perlite, and Pumice, are procured from trusted, long-term partners to uphold the highest quality standards.

Dedicated Processing Facilities

  • Bark is processed in facilities designed exclusively for Horticultural Bark, eliminating cross-contamination.

  • Bark is washed to remove stones, soil, and other foreign materials.

  • To protect nursery staff and customers, bark is passed over high-powered magnets to remove any ferrous metals like nails.

Careful Storage & Handling

  • Bark is matured on sealed asphalt windrows to prevent contamination and waterlogging.

  • Effective weed control and strict site management practices protect the integrity of our products.

  • All chemicals are stored in secure, dedicated facilities to avoid cross-contamination.

Comprehensive Quality Control

  • Bark pH is adjusted early using large paddle mixers to ensure consistency in this product right from the very beginning.

  • Throughout maturation, we monitor pH, EC (electrical conductivity), temperature, oxygen, and moisture levels to optimise quality.

  • Quality is consistently tracked and managed throughout every stage of production.

Precision Blending & Mixing

  • Fertilisers and media are blended through large, specialised paddle mixers for a completely uniform final product.

  • All mixing takes place in clean, horticulture-only environments free of contamination.

Development & Accreditation

Learning more to support a growing industry.

  • Technical advice is readily available for mixes and any related growing challenges.

  • Ongoing benchmark trials are conducted to continually refine products and materials.

  • Intelligro is a proud, long-time member and supporter of key industry organisations like the Canterbury Horticultural Society, International Plant Propagators Society (IPPS), and New Zealand Plant Producers Incorporated (NZPPI).

  • We hold NIASA Accreditation (Nursery Industry Accreditation Scheme Australia), recognised for setting "Best Management Practices" for growing media suppliers.
