Plant Science for Gardeners

133 pages. Temps de lecture estimé 1h40min.
Understand how plants actually work to become a more successful, confident gardener. Science-based guide explains plant biology in practical terms, enabling gardeners to make informed decisions about watering, fertilizing, pruning, and troubleshooting based on how plants actually function. Why Plant Science Knowledge Multiplies Garden Success: When you understand what plants need and why, every garden decision becomes logical rather than guesswork. This knowledge prevents costly mistakes and maximizes plant health and productivity. What You'll Understand: Plant nutrition fundamentals for providing exactly what plants need, when they need it Water management science that prevents both drought stress and root rot Photosynthesis optimization through proper light management and leaf care Growth regulation through pruning, training, and environmental manipulation Stress identification and response for healthier, more resilient plants Practical Garden Applications: Gardeners with plant science knowledge report fewer plant losses, better harvests, and greater confidence in trying new plants and techniques. Garden smarter, not harder, through scientific understanding. Essential for gardeners ready to move beyond following rules to understanding principles.Introduction    Introduction to Plant Science    Organization of the Book    Terms Used in This Book 1.
