The lessons learned from observing and working with nature help to relieve the fears and anxieties of modern society. It is interesting to note that gardening has become a successful tool for the treatment of seriously ill mental patients. We've noticed that our children readily consume homegrown vegetables, but often leave much of the store bought produce for the compost pile. As skills and confidence grow, gradually increase the garden's size to fit your time and energy commitments. Also, read one or two basic gardening books, but don't get overwhelmed with the intellectual process - you will learn far more working with your soil and plants.
Most gardeners are very happy to share knowledge.
Remember to take the time for casual observation. Much can be learned from watching the progress of your garden over the months. Each specific site has its own unique characteristics and requires the gardener to adapt accordingly. Be kind to the land, the plants and yourself.
