Diagnosing Plant Problems
What's Wrong With My Plant (And How Do I Fix It?), written by David Deardorff and Kathryn Wadsworth (Timber Press, 2009), is an excellent reference book containing an easy system for visually diagnosing any plant problem and matching it to the right cure. The book presents easy-to-follow illustrated flow charts, organized by where on the plant the symptoms appear, allowing you to accurately diagnose the problem. It doesn't matter whether it's a houseplant, perennial, vegetable, tree, or shrub, or whether the problem is affecting the roots, stems, flowers or leaves -- the flow charts will help you determine the cause of the problem. Once you've pinpointed the problem, you'll find organic solutions to solve the problem and help you nurse your plant back to health.

'Allgold' Witchhazel
Witchhazel (Hamamelis intermedia 'Allgold') is a true harbinger of spring with its bright yellow flowers that open in February and March. The flowers are actually yellow at the base with red tips. This shrub grows slowly to about 12 feet tall and wide and makes a handsome addition to any landscape. The foliage turns bright red in the fall, rivaling any maple in the neighborhood. Witchhazel is hardy to USDA Zone 5 and tolerant of a wide range of conditions, but performs especially well in rich, slightly acid soil in a semi-shady situation.
