Daktuinsubstraat Sedumteelt

Specifically for the cultivation of Sedum, we offer two types of substrate; Sedum cultivation peat, and Sedum cultivation tray. The substrate Sedum cultivation peat is made for the cultivation of the Sedum mats. This substrate contains a high number of organic particles from the added high-quality RHP compost. This results in a higher and prolonged nutrition supply for the planting. The substrate Sedum cultivation tray is made for the cultivation of Sedum in trays, also known as clayettes. A thicker layer of substrate is applied here, which afterwards is placed onto the roof in its entirety, without additional substrate. The density when saturated is important in this process.


• Clean and free of weed
• High organic matter content for nutrient- and buffer capacity
• Good water capacity with optimum water permeability
