If you are curious as to how and why plants respond to different environmental stressors, then “How Plants Work: The Science Behind Amazing Things Plants Do” is a near-perfect antidote. The book by Dr. Linda Chalker-Scott, an associate professor and extension urban horticulturalist at Washington State University, explains various plant phenomena in useful, understandable ways and further clarifies the information with color photos and illustrations adjacent to the text.

According to Chalker-Scott, “What we gardeners most want to know is how plants work so that we can have gardens and landscapes that are healthy, beautiful, and don’t need constant attention for fertilizers and pesticides.” Can I hear an amen for that quote? Furthermore, Chalker-Scott recognizes that most gardeners are not scientists; she therefore writes about science without detailed jargon so that a gardener’s inquiring mind will usually be satisfied with answers on many practical topics.

Gardening the “right way” will often save you time and money, but you need to set aside some past practices. Often these have been handed down and even described in books that are out-of-date and can best be described as myths. A full-service garden center often has a garden “apothecary” full of all kinds of potions and is surely willing to sell unneeded products for the garden.

  1. Vitamin B1 for transplants
  2. Epsom salts
  3. Biostimulants
  4. Amending soil before planting trees and shrubs
  5. Landscape fabric (geotextile, weed barrier)
  6. Gypsum
  7. Compost tea
  8. Water crystals (hydrogel)
  9. Antitranspirants
  10. The season for tree planting

Even if you have been paying only scant attention to garden media (newspaper, TV, radio), you must have read or heard something like this: GET A SOIL TEST! Do your eyes roll and perhaps tune out this advice? Chalker-Scott expounds on why this is an essential requirement. Perhaps best put in human terms, getting a soil test is something like having your blood tested in order to find out which things are right and which are recommended for change. In a similar vein (no pun intended), a soil test will det
