Last month's article discussed the differences and benefits among various mulches and their benefits. This topic is a logical segue into gardening on limestone soil where retaining moisture and nutrients is essential. Scott Ogden's seminal book, Gardening Success with Difficult Soils (Taylor Publishing Co, 1992), covers this area very nicely and is a short easy read. Besides providing invaluable approaches to gardening under a wide array of climate conditions, it also covers a wonderfully diverse palette of flora from turfs to wildlife attractions. While some of the suggestions may now be dated (which may encourage circumspection among gardeners), such as crape myrtle, bermuda grass and vitex, the book has a preponderance of positives. For instance, strong consideration is given throughout the book to color and texture coordination, such as his discussion of border flowers in which he laments the unavailability of colors other than mauve to magenta which conflict with colors in the yellow-orange spectrum. Odgen suggests that contrasting colors can be effective as long as the intensity of the colors is similar, a technique to be used sparingly since it can be somewhat gaudy. Such nuanced tidbits are common. Deciduous magnolias, although disliking lime soil, can do very well there because of their shallow roots, when planted in amended soil and covered with mulch. One area where the book really shines is in its sixty-four glossy illustrations which illustrate not only gorgeous specimens but also indirectly illustrate Scott Ogden himself, the plant explorer who introduced so many incredible plants to the gardening world.

Happy Gardening!
