Updated Version of Handbook of Cycad Cultivation and Landscaping
The Cycad Specialist Group is pleased to present Volume 2 of the ‘Handbook of Cycad Cultivation and Landscaping’, a comprehensive guide for cycad enthusiasts, horticulturists, and conservationists.
This guide consolidates essential knowledge about cycad care, propagation, and conservation, providing accessible insights for botanical gardens, nurseries, and serious hobbyists. It features practical tools such as the Decision Table, which offers at-a-glance advice on soil requirements, irrigation, pest tolerance, and landscaping considerations. The handbook also addresses the challenges of growing cycads in various climates and environments. A supplemental spreadsheet for the handbook with data for different species is provided here.
We hope this resource inspires and equips readers to contribute to the understanding and protection of cycads worldwide, fostering appreciation for their unique beauty and ecological importance.
This is the Second Edition of the original handbook published in 1995, available for download below.
