Book excerpt: The nuisance caused by weeds sprouting in your otherwise thriving garden may make you want to reach for the herbicide, but as Flowerdew writes in this installment of his Bob’s Basics series, weed control can be much more simple, inexpensive, and eco-friendly without chemical intervention. Because every weed is best removed with a different method, Weeding Without Chemicals begins with a discussion of the various weed categories. No matter what sort of weed is plaguing your garden, Bob has a chemical-free way to keep it under control.
