Simple and fun to make Halloween Witchs Glitter Broomstick Tutorial DIY project. If twigs of witch's brooms are grafted onto normal rootstocks, freak trees result, showing that the attacking organism has changed the inherited growth pattern of the twigs. The broom growths may last for many years, typically for the life of the host plant. The phenomenon can also be caused by other organisms, including fungi, oomycetes, insects, mites, nematodes, phytoplasmas, and viruses. This can be caused by cytokinin, a phytohormone which interferes with growth regulation. In cases of witch's broom, the normal hierarchy of buds is interrupted, and apices grow indiscriminately. The growth of an offshoot is limited by the auxin, while that of the parent branch is not. A tree's characteristic shape, or habit, is in part the product of auxins, hormones which control the growth of secondary apices.
