Nutrient deficiencies of bedding plants; a pictorial guide for identification and correction.
Sixteen elements are said to be essential for plant growth, from boron to zinc. Gibson (quality control manager for a substrate manufacturing company and nutrient testing facility in Anderson, South Carolina) and fellow plant scientists present information for diagnosing nutrient deficiencies in popular annual bedding plants. Step-by-step protocols are given for establishing a substrate testing and corrective program. The text includes color illustrations of symptomatic plants, nutritional recommendations for seed- and tissue-propagated plants from angelonia angustifolia (summer snapdragon) to zinnia, handy summary tables, and author contact information.
