Gardening Rhythms is a show that depicts a natural method of gardening lifestyle using observation, innovation, common sense and understanding the practical use of micro biology. This show teaches you how to garden without using chemicals and fertilizers, and it’s designed to give you tips to become a savvy home gardener.

As Paul got older, he supported himself through college doing landscaping.
The author's knowledge of ecology, soil ecology, soil food web, California's Native biological cycles, plant succession and new soil creation through the use of only plants has also evolved. Using the methods and processes that are applied to over 30 patents filled in the USA by the author, continued innovation occurs with new breakthrough in new soil creation and Aquaponics with soil food web biology innovations.
