Our collaboration is built on progress
Kwekerij Roos and Klasmann-Deilmann strengthen partnership
Kwekerij Roos is a prime example of a nursery that recognised the potential of high-quality, future-proof substrates at an early stage. Ronald Roos was one of the first growers in Boskoop to start using potting soil from Klasmann-Deilmann. This decision has led to a long-term partnership founded on reliable deliveries, quality and innovation.
Since 2019, Kwekerij Roos’s operations manager, Twan Kranenburg, has been overseeing production planning, potting and substrate recipes. The properties of the substrate are carefully and consciously composed. This involves considering the correct moisture content, the type and quantity of fertilisers, and the proportion of peat. While Twan acknowledges that the market is facing challenges due to uncertainty surrounding the availability of raw materials, he does not encounter these issues himself at Klasmann-Deilmann. „A relationship works well when you can rely on each other,“ he says. „You give what you can, but you deliver when you have to.“
Working together to develop the substrates of the future
Sustainability is at the heart of our collaboration. Kwekerij Roos now uses mixtures containing an average of 50% less peat, and is conducting pilot projects with blends containing 90–100% less peat. These projects require constant adjustments to the cultivation strategy, as the new mixtures react differently to traditional substrates. Klasmann-Deilmann is proactively contributing to the search for alternative raw materials, ensuring that the quality Kwekerij Roos delivers throughout the supply chain is not compromised.
Supplier of quality and reliability to the international market
Kwekerij Roos supplies retailers, DIY stores and garden centres throughout Europe. The company is renowned for its consistent product quality, prompt deliveries and flexible service. Hibiscus and lilacs are the nursery’s distinctive specialities. With over 30 permanent staff and 15 hectares of cultivation space in the Netherlands and Poland, Roos delivers plants in optimal condition daily.
The reliable delivery of Klasmann-Deilmann substrates fits seamlessly into the nursery’s way of working. Improvements to the Klasmann-Deilmann webshop and specific delivery agreements make it easier than ever for Twan and his team to organise efficient planning and production. “For a number of substrate recipes, we can specify exactly what needs to be delivered in the morning or afternoon. That’s reassuring and gives us peace of mind,” he emphasises.
Shared motivation for sustainable entrepreneurship
Kwekerij Roos’s sustainable ambitions extend beyond the substrate. The nursery uses 100% recyclable, carbon-free pots and RHP- and RPP-certified potting soil. It also uses environmentally friendly crop protection products, plant enhancers and accurate water monitoring systems. Waste streams are separated and the greenhouses are equipped with modern energy screens. Furthermore, cultivation is completely neonicotinoid-free.
Kwekerij Roos’ collaboration with Klasmann-Deilmann proves that high-quality cultivation and reducing the CO₂ footprint can go hand in hand. We are working step by step towards a future in which quality, reduced environmental impact and supply security reinforce each other. Both companies fully support this approach.
