Scatter the wilted leaves throughout potato trenches just before planting, to fertilise the crop and improve their flavour! Once established, this quick growing plant can be cut 3 or 4 times throughout the growing season, for a constant supply of nutrient rich, organic, comfrey fertiliser. Height: 100cm (40”). Spread: 75cm (30”).
