Van der Knaap is a group of companies that specialises in developing high quality, organic solutions for rooting and growth of plants. By offering complementary activities, Van der Knaap has rapidly become one of the top companies in professional horticulture, both nationally and internationally.

The rooting and growing products Van der Knaap Group supplies are based on peat moss and coco peat. We have made a conscious choice for materials that are 100% recyclable and therefore environmentally friendly.

We accomplish high quality products by controlling the whole production chain, from raw material to end-user. The physical and chemical characteristics of raw materials are checked in our own laboratory from extraction to distribution. This way we can maintain the high quality standard we have set for ourselves. Our quality management system is RHP and ISO 9001:2008 certified.

Our products are developed in close collaboration with growers and growers’ associations. Ranging from improvements in potting soil mixtures and substrates to completely new products, Van der Knaap has the best solution for practically every crop and cultivation phase.
