[.ca] Gardening Success with Difficult Soils: Limestone, ... (ISBN 0878337415)

this is an invaluable book for Central Texas gardeners:
This is the most practical, useful, and enjoyable book on gardening that someone in the Texas Hill Country could ever want! It's not as big or comprehensive as the Wasowskis' "Native Texas Plants: Landscaping Region by Region", but that's because it focuses on the challenges of gardening in these "difficult" (nice word!) soils that we live with. Ogden's observations and advice about dealing with our limestone and caliche, and his reality-based recommendations of plants to use and the ones to avoid, gave me hope, encouragement, and new ideas for making this corner of the world a more beautiful place! It's got some great color photos, too.

For hot, dry and high pH soils (Texas Hill Country):
Dry limestone based soils such as the Edwards Plateau area of Texas and other places in the southwest, provide a major challenge to gardening which is addessed in this book. In such areas many plants simply will not grow well. Trying to get them to do so is an exercise in frustration and general garden books can lead you far astray. This book is not about how to try to change your soil, high pH soils cannot be effectively acidified. The book is about plants, trees, shrubs and varieties that do well in dry calcarious soil conditions. It will save you a lot of time, money and frustration if you face these conditions. A great book, a gold mine of information.
