The Informed Gardener

I came across The Informed Gardener by Linda Chalker-Scott during the BEA conference in May. It was one of the new books the University of Washington Press, whose booth was right across from ours, was promoting front and center in their display.

The beautiful cover first caught my eye, but I first suspected the book might be geared towards gardeners in the Pacific Northwest, since that's where it was published. That wasn't the case, though-it will be a useful book to any gardener in any part of the country. This is a collection of columns that the author had written since 2000 on various horticulture myths and misconceptions. (Her most current columns can be read on her web page.)

The book is broken down into six sections, including Critical Thinking, Understanding How Plants Work, How/What/When/Where to Plant, Soil Additives, Mulches, and Miracles in a Bag/Bottle/Box. Each column is neatly broken into sections: the myth, the reality, the bottom line, and a list of references. One of the myths she dispels is that watering on a hot sunny summer day (like today!) will scorch your plants' leaves. After explaining various causes of leaf scorch (including too little/too much water, salt, and poor root health) she recommends in her "bottom line" section to water plants anytime they show signs of drought and to preferably do that watering in the morning, to avoid over-fertilizing, and to make sure the plant site is optimal for root and shoot growth.

One of the other practices she takes issue with is backfilling a plant or tree hole with soil additives. I've always thought it was a good idea to add a little organic matter when I'm transplanting tomatoes or other plants, but she argues while the roots may grow vigorously for awhile, when they reach that edge between the organic matter and the native soil they may turn back towards the organic matter rather that reaching outward, which establishes a weak root system. She also suggests that the organic matter is too porous, and water will tend to move along to the native soil. Her recommendation is to instead add the organic matter as a top dressing, which you can continue to maintain without disturbing the plant.

I enjoyed this book. It was a fast read that encourages common sense, efficient, and cost-effective gardening. I'll probably re-visit it next spring before I head into the next gardening season.
