Dragon dung fertiliser was a potion used to help magical plants grow, such as the Venomous Tentacula. Its main ingredient was dragon dung, the potion's namesake.[1]

History[]

During the first Herbology class in the 1986–1987 school year at Hogwarts School of Witchcraft and Wizardry, Professor Pomona Sprout revealed to Jacob's sibling that she had spent her summer conducting several experiments on the composition of dragon dung fertiliser.[2]

During the 1987–1988 school year, Jacob's sibling, Charlie Weasley, and Liz Tuttle used dragon dung fertiliser and the Herbivicus Charm to quickly establish a field of Bubotubers in a clearing in the Forbidden Forest. These were intended as a food source for a forest troll that had been foraging for them near the Forest Lake, preventing the Forbidden Forest Centaur colony from gathering water there.[3]

In 1997, Horace Slughorn asked Harry Potter to brew some in order to collect the highly valuable leaves of a Venomous Tentacula.[1] The fertiliser was also noted to be Professor Pomona Sprout's preferred type.[4]

Mathilda Grimblehawk's partner used dragon dung fertiliser to restore a sapling Wiggentree brought from the forest by Don Harrison.[5]

Behind the scenes[]

  • In the handheld versions of LEGO Harry Potter: Years 1-4, a fertiliser exists which also contains dragon dung as an ingredient (along with other things), that may in fact be this potion or related to it.
