- "Harry learned quickly not to feel too sorry for the gnomes. He decided to just drop the first one he caught over the hedge, but the gnome, sensing weakness, sank its razor-sharp teeth into Harry's finger and he had a hard job shaking it off -- until -- 'Wow, Harry -- that must've been fifty feet....'"
- —Harry Potter has his first experience with de-gnoming.[src]
De-gnoming was a term used to refer to the process of ridding a garden of gnomes. This was normally accomplished by physically picking up the gnomes and expelling them from the garden in question. Newton Scamander recommended in Fantastic Beasts and Where to Find Them that swinging the gnome around one's head until dizzy and then dropping it over the garden wall was sufficient, but some wizards, like the Weasley family, preferred to throw the gnomes as far as possible, sometimes even having competitions as to who could toss a gnome the furthest. Alternatively, a Jarvey can be used to de-gnome a garden, though this is considered inhumane by most wizards, as the Jarvey's methods are "brutal".
Aside from Fantastic Beasts, the subject of de-gnoming is also covered in Gilderoy Lockhart's books Gilderoy Lockhart's Guide to Household Pests and Marauding with Monsters. Given Lockhart's status as a fraud, it is unlikely that these books contain any information on the subject that Lockhart did not steal from a second-hand source. Before this became known, however, Molly Weasley suggested her children consult the title for information on de-gnoming, though they insisted that they already knew how to do it.
