This water lily soil from Ubbink is a highly nutritious pond substrate for the optimal growth of your water lilies. The special composition and structure of the soil ensures a good circulation of oxygen-rich water along the roots, while peat (40%) and blue clay (55%) support healthy growth. The humic acid in the peat naturally inhibits algae growth, while the clay gives stability. The addition of sand helps to loosen the soil's structure. Always use a large enough plant basket or pocket!
