Exercise. Gardens get us outside. The sun they shine on us gives us warmth and vitamin D. The bending and walking and lifting they require offers light exercise. The dirt and insects they expose us to can make us build up antibodies against different germs and bacteria, boosting our immune system. "An apple a day keeps the doctor away." There is reason in the rhyme. The time you spend in your gardens means fewer hours sick and at the doctor's office.
Mind. Gardens remind us where our food comes from. Gardens reconnect us to the earth and remind us that we depend on the earth for our living. This perspective, often forgotten in busy life, reminds us, too, that we and other people share a special kind of life together. Not only do gardens encourage us to reevaluate ourselves and our relationships, but they invite others into our gardens, into our kitchens, and to our dinner tables.
