HEALTHY TREES AND DYING TREES

Trees should be healthy and thriving. Remove any dead or dying trees. Trees that are dead or in poor condition will drain vital chi from the occupants of the home. This is particularly important if someone in the home is elderly or ill. Trees planted on the eastern side of the property will promote good health.
