How Plants Work brings the stranger-than-fiction science of the plant world to vivid life. It explains how plants tell time, how they move to follow the sun and capture food, and why they change color. Linda Chalker-Scott, of the popular blog The Garden Professors, uncovers these and other fascinating mysteries in this engaging and accessible introduction to plant physiology. By revealing the science behind what plants do every day, this book arms...

If you can't trust the Internet home remedy or the local gardening salesperson, whom can you trust? Make science-based gardening decisions by assessing the credibility, relevance, accuracy, and purpose of the information you read. Learn the role played by peer review, the crucial difference between correlation and causation, and how to watch out for over-extrapolation and misapplied science.

There is no lack of chemicals to get rid of the pests in your garden - whether that pest is a plant, insect, or other organism. But for long-term health, integrated pest management provides a better, systematic, science-based approach with a minimum of chemical inputs.

Many of us make our landscape choices based on plant aesthetics. Instead, learn to first identify your location's topography, prevailing winds, hydrology, soil type, and other environmental factors. Then you'll be able to choose a plant well-suited for the long term. And you'll avoid season after season of frustration.

Two specific transformation stories - a wetlands restoration and a home garden project - reflect the benefit of science-based planning by considering soils, temperature, sunlight, moisture, water table, and likely pests. Learn how to become a citizen scientist and contribute to the field by asking the hard questions and knowing how to assess the strength of the answers.

If you have a garden in the U.S., chances are you're familiar with the damage caused by English ivy, kudzu, purple loosestrife, and/or the tamarisk tree. Each of these hardy plants can quickly create a monoculture, driving out other plant species and limiting the availability of diverse animal habitat. Learn the best science-based mechanisms to control these plants.

Half the battle of successful landscaping is starting with the healthiest specimens - not, as we sometimes prefer, the largest. Learn how to inspect nursery plants from the crown to the ground for evidence of quality and health, and how to estimate root health by checking for suckers on single-trunk trees, root flare, surface roots, and the "tippy test."

While it seems intuitive that vegetables grown in your home garden will be safer and healthier than those purchased at the supermarket, that could be a dangerous assumption. Does your garden soil contain elements of concern, especially cadmium or lead? If so, learn how to best respond - whether in plant choices or creative garden design.

The goal of fertilizing is to match your soil and plant needs - micro- and macronutrients, and other chemical requirements - with the appropriate sources of nutrition. By understanding your specific soil test results, you can determine which nutrients are deficient, which might already be present in toxic quantities, and whether or not to buy organic.

In addition to its aesthetic value, your landscaping can provide privacy, protect soils from erosion, moderate temperature, manage storm-water runoff, provide wildlife habitat, and more. Learn how to select the appropriate plants with respect to morphology, growth rates, and physiology to help achieve your specific goals for various locations on your property.
