About this book:

"Advanced Propagation of Native Plants" is a comprehensive guide for professionals and advanced hobbyists, bridging scientific understanding with practical protocols for the successful propagation of native plant species. The book emphasizes methods that respect genetic integrity, local adaptation, and the practical realities of nursery production. It contrasts native plant propagation with conventional horticulture, highlighting the complexities of dormancy, genetic variability, and the critical importance of provenance.

The book is structured into several key sections. It begins by establishing the ecological, restoration, and market contexts for native plant propagation, including ethical sourcing and population genetics. The initial chapters delve into seed biology, covering dormancy, viability, and longevity, and provide detailed protocols for seed collection, cleaning, storage, and dormancy-breaking treatments like stratification, scarification, smoke, and chemicals. This section also addresses optimal sowing designs, considering depth, temperature, light, and moisture, and outlines the setup and management of germination facilities.

The second major part focuses on clonal propagation. It outlines meticulous stock plant management to maintain juvenility and vigor for cutting production, detailing the science of adventitious rooting, including the roles of auxins, wounding, and carbohydrate balance. Practical techniques for softwood, semi-hardwood, hardwood, and evergreen broadleaf cuttings are covered, alongside layering, division, and grafting methods for difficult taxa. The book also introduces micropropagation and in vitro conservation for recalcitrant or high-value species, emphasizing sterile techniques and acclimatization.

Substrates and environmental control are thoroughly explored, with chapters dedicated to substrate science, custom substrate mixes tailored for diverse functional groups (grasses, forbs, shrubs, trees, wetland, alpine species), and container design, including air-pruning for optimal root architecture. Irrigation and fertigation strategies are detailed, focusing on water quality, scheduling, and nutrient delivery aligned with native plant needs. Environmental control—light, photoperiod, temperature, and humidity—is discussed in depth, along with the importance of beneficial microbes and mycorrhizal inoculation.

Finally, the book addresses the operational and post-nursery aspects of native plant production. It covers integrated pest management (IPM) for insects, diseases, and weeds, and outlines essential sanitation, quarantine, and biosecurity protocols. Chapters on scheduling, batch tracking, and production planning provide frameworks for efficient nursery operation. The concluding sections cover quality assurance, including grading, stress testing, and readiness for outplanting, and offer guidance on successful outplanting and post-establishment care. Throughout, the book stresses the importance of combining rigorous technique with ecological responsibility, ensuring that native plant propagation supports ecosystem function and resilience.
