Durable and Reliable

Our Quality Certifications

At Olaf Nijenkamp, we believe it’s important that our plants are not only strong and beautiful, but also grown sustainably and responsibly. That’s why, upon request, we work with certified growers who meet strict standards regarding the environment, quality, and origin.

PlanetProof-certified 12021

As a wholesaler, we are currently in the process of obtaining PlanetProof certification under number 12021. This means we actively contribute to a more sustainable sector: less environmental impact, greater biodiversity, and transparency throughout the supply chain. This certification applies to our role in the distribution and processing of plants.

Collaboration with Certified Growers

We source our plants on demand from suppliers with one or more of the following certifications:

SKAL for certified organic cultivation
MPS-A, MPS-GAP, and MPS-Socially Qualified for environmentally conscious and socially responsible cultivation
Groenkeur quality certification for the professional horticulture sector
Milieukeur (now integrated into PlanetProof) for products with a demonstrably lower environmental impact

This enables us to support landscapers, government agencies, and landscaping contractors in sustainable planting and in meeting bidding requirements or policies related to biodiversity and the environment.

Transparency and Traceability

We ensure careful documentation of origin and certification for each batch. Upon request, we provide the necessary documentation so that you know exactly what you’re planting and that you meet your client’s requirements.
