Ortho's Home Gardener's Problem Solver
Although Ortho's Home Gardener's Problem Solver, edited by Michael McKinley (Meredith Books, 2001; $25), is not a southern book, it has relevance to the South and deserves a look by any beginner or serious gardener. It's easy to read and well organized with excellent photographs, and it covers the gamut of basic horticulture dilemmas. Got a problem? Identify the cultprit by cruising through the diagnosis checklist, then isolate the affected plant. If you know what the trouble is, check the extensive index and go right to it.
