Those of us who grew up in tree-lined shady neighborhoods often took trees for granted. As life has become more urbanized and trees have disappeared to make more lanes for traffic, trees have become more important. Planting our own trees opens a whole new world. What kind of tree, what needs for light and shade, what climate,.. These considerations brought a sense of harmony and beauty which is mentally restful, physically stimulating, and spiritually nourishing. There's a sense of personally connecting with an open space. Also a sense of contributing to the larger community by providing shade, oxygen, fragrance and shelter for insects and birds.
