2. Feng Shui taboo for planting elms: When planting elms, don't plant elms in front of the window, because this will block out the sun, and the indoor yang will be insufficient, which will affect the lighting, so the effect of elms will be very small and will also affect the life of family members. Never let elms have dead branches when maintaining them. Elm can restrain Yin Qi, but we should know that dead branches are one of the sources of Yin Qi. If there are dead branches, it will have an impact on the role of elm in exorcism. At the same time, maintain the elm tree and don't skew it. Elm is a feng shui tree after all. If it is crooked, it will have an impact on feng shui at home.
