Mulberry's homonym is obvious. Mulberry is homophonic with "mourning" If mulberry trees are planted in front of the door, it means that there may be a funeral. In geomantic omen, it is also considered that mulberry is unlucky, because mulberry belongs to the shade and is easy to attract ghosts. Ghosts will gather in places with heavy yin qi, which will easily lead to the invasion of ghosts, and people will be weak and sick because of excessive yin qi.
2. Willow
Willow trees are also related to funerals. There is a custom in many rural areas. When a funeral is held, the direct descendants will hold a funeral stick made of willow wood. There are also some evocation flags made of willows, so willows have the function of evocation. Planting willows behind the door is to bring ghosts to your house.
3. Poplar
Poplar is also called ghost clapping. I believe many friends have heard of it. Because when the wind blows over poplar, poplar leaves make a sound like someone clapping their hands, so it is called ghost clapping. Poplar is also a shady tree in geomantic omen, and it is easy to provoke ghosts, so no one in the countryside grows ordinary poplars in the yard.
4. Sophora japonica
You can tell by the name of Sophora japonica that it has something to do with ghosts. Sophora japonica is also a shady tree in geomantic omen, and it is called a ghost in the forest. Sophora japonica has a heavy yin, and some trees even grow faces, and the older the tree, the more faces there may be, which naturally becomes a kind of ghost tree.
5. Melia azedarach
This kind of tree is rare in cities, but it is abundant in rural areas. This kind of tree is also called neem. Because its fruit is bitter, no one has a reason to eat bitter fruit, so it is regarded as an ominous tree, and it will not be planted at home to find its own bitter fruit. In geomantic omen, neem is also a shady tree, which is easy to attract ghosts and looks ugly. No one in the family can plant it.
