Comfrey 'Bocking 14'

Symphytum x uplandicum 'Bocking 14', Russian Comfrey

Grow your own soil conditioner! Comfrey 'Bocking 14' contains high levels of basic NPK nutrients and because it is a sterile hybrid, it won't self seed all over your garden.


The nutrient rich foliage of comfrey can be used as a compost activator, mulch, or soaked in barrels of water for 3 to 5 weeks to make a useful liquid feed for tomatoes and beans. 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”).
