What is the feng shui about planting trees in the courtyard?

J what is the feng shui of planting trees in the courtyard? The following aspects should be paid attention to in the geomantic omen of planting trees in the courtyard: there are choices for planting trees in the courtyard, and geomantic omen thinks that plants are divided into two categories. There are two criteria to divide the perpetrators: one is whether there is poisonous gas or venom, and the other is whether it is determined according to the characteristics, meanings and even homophones of plants. People tend to converge to this view in real life. Palm, citrus, bamboo, Toona sinensis, Sophora japonica, osmanthus fragrans, Ganoderma lucidum, plum, banyan, jujube, pomegranate, grape, begonia, etc. 13 are auspicious plants, and 8 plants, such as peach, willow, wormwood, ginkgo, cypress, Cornus officinalis, Sapindus mukoraiensis and gourd, have the function of exorcising evil spirits. According to the geomantic theory, it is advisable to plant big trees in rows to block the suffocation around the house. In order to supplement this situation, when the house is built on the plain or in a wide area around it, trees and flowers can be used to create a four-god pattern of "Zuo Qinglong, Zuo Baihu, Qian Suzaku and Hou Xuanwu", that is, big trees are planted in the back of the house, medium trees are planted on the left and right sides, and low shrubs or grass are planted in front. This way is understandable from the aesthetic point of view, which meets people's psychological needs of finding a "land of geomantic omen". Particles that strongly stimulate the sense of smell have adverse effects on patients with heart disease and hypertension. For example, the flowers of oleander are poisonous, and the fragrance of flowers makes people fall asleep easily, which reduces human function. Tulip flowers have soil alkali and are easy to fall off when they come into contact with hair too much. These trees are fierce and should not be planted in the yard. There are also some people who take the shape of the tree as unlucky, such as "the big tree is weird, which hurts their reputation", "the tree is hunched over, and all the money has been returned", and "the tree is like a lying cow, and it is sick". All ugly, dignified and abnormally developed trees are fierce. I'm afraid this is a psychological effect or a traditional humanistic aesthetic concept at work. The number of trees planted Feng Shui advocates reasonable close planting. When the periphery is large and narrow, don't plant a variety of trees, otherwise it will help to shade; Only the sparse left and right behind are densely planted to block their emptiness. Ancient geomantic classics have some conclusions about this: "Peach blossoms are east, plum dates are south, elm trees are west and plum trees are north", "It is unlucky to hang willow in front of the door", "Sophora japonica is in the middle door of Fu Shan III", "After the elm cabin, ghosts are not close" and "double dates in front of the door, and bamboo and trees are all green around it to make money". From the above conclusions, combined with modern scientific knowledge, it is found that it also contains nature. For example, the peach poplar trees are planted in the east because the sunrise is the first in the east, the willow trees germinate earlier, and the peach blossom is one of the earliest flowering plants in spring, so it is more reasonable to plant them in the east, and the elm trees are wet plants, so it is more appropriate to plant them in the west when the sun is not afraid. I hope it works for you!
