Bakker Wetkeep granules can be added to your potting compost to hold moisture and essential nutrients for longer. The granules soak this up like a sponge and release it all gradually to the plant(s). Just mix Bakker Wetkeep to your potting compost before planting, then plant up as you normally would. Bakker Wetkeep will retain moisture and nutrients for longer and the presence of lime in the mix keeps the pH levels good for plants in large planters on the patio/decking! Contents: 2.5 Kg.
