Gardening Naturally – Book Review
By Liz Sellors, Master Gardener

Gardening, Naturally is a chemical-free handbook for the prairie gardener, co-authored by Hugh Skinner and Sara Williams. The book was written in 2011 and was published by Coteau Books of Regina, Saskatchewan. Gardening Naturally is a well written and easy-to-use guide specifically intended for Canadian prairie gardeners who are interested in effective ways of eradicating pests and diseases from the garden without resorting to chemicals. The book addresses alternatives to the use of chemical pesticides, insecticides and herbicides. Chemical products intended for use by gardeners were developed in the late 1940’s. Until that time solutions for addressing pests and diseases in the garden were largely based on folk wisdom, much of which began to be lost once chemicals were introduced. But, over the last few decades, environmental movements have once again looked to natural ways of dealing with garden pests and diseases. With the move to green solutions, scientifically based alternatives have begun to emerge and are gaining notice. It was the emerging interest in alternatives to chemicals for the garden that was the inspiration behind Gardening, Naturally.

The over-arching theme of this well-laid-out, well-illustrated book of alternatives to chemical use in the garden addresses the fundamentals of maintaining a healthy garden through natural means. The book first examines the history of controlling pests and diseases in the garden, starting with a look at the use of organic solutions that had been developed over centuries, and how they began to be replaced by the successful marketing campaigns of the companies producing chemical solutions for gardeners. The promotion of the idea that chemicals were the answer to the perfect garden was in reality a concept that ensured repeat business by making plants dependent on chemicals. The result was unimaginable harm. Gardening, Naturally points the way to a return to dealing with garden issues organically.

Through the use of alternatives to insecticides, herbicides and pesticides, the book demonstrates how to ensure that the basic needs of plants are met. The book is well researched and scientifically based. It not only looks at how to work with natural products, but also addresses why change is crucial. It looks at the importance of changing our attitude toward insects; the importance of identifying of insects and why their survival is crucial to human survival. It looks at essential garden practices like soil testing, water conservation, effective organic lawn care and weed control. It looks at growing food successfully without chemicals and recommends the best vegetables to grow in the prairie garden. Other sections are devoted to flowers, bulbs, and vines suitable for the prairies. It also includes a comprehensive section on trees and shrubs for the prairie gardener.
