Discover the secrets of thriving fruit trees with Susan Poizner, founder of Orchard People and author of multiple books on fruit tree care. In this comprehensive conversation, Susan shares her remarkable journey from BBC journalist to fruit tree expert, sparked by a community orchard project that taught her valuable lessons through trial and error.
Susan reveals the often-misunderstood purpose of pruning – not merely for size control, but as the essential foundation for disease prevention and quality fruit production. She expertly breaks down the science behind why proper pruning creates a healthier environment within the tree canopy, preventing the damp, dark conditions that fungal diseases thrive in. You'll learn the crucial differences between winter pruning (which stimulates growth) and summer pruning (which controls size), plus how to choose between open center and central leader structures based on your local climate conditions.
Beyond pruning, Susan shares practical wisdom on combating common fruit tree challenges like apple maggot, codling moth, and canker. Her innovative solutions include dormant oil sprays, orchard socks for pest prevention, and proper cleanup practices that break disease cycles. You'll discover why soil preparation matters tremendously and how annual compost application supports tree health from the roots up.
Most fascinating is Susan's insight that truly healthy trees naturally repel pests and diseases. By understanding and working with your trees' natural biology, you can create resilient fruit trees that produce abundantly with minimal intervention.
Whether you're an experienced orchardist or planning your first fruit tree, this episode provides the essential knowledge to form a successful partnership with these generous plants that can provide beauty and bounty for decades to come.
