Hey guys, this is the free eBook Version of my newest book CACTUS CULTIVATION: TRICHOCEREUS aka TRICHOCEREUS CULTIVATION. A completely free eBook without any strings attached.
You can either get it by checking out with the free eBook in your cart or simply subscribe to our newsletter and you will be automatically sent the eBook! Make sure to verify your email and check the spam folder. 
The current page count is roughly 340 pages (A4) and we will edit and expand it on a regular basis. Everyone is invited to donate pics of cool and unusual stuff for later editions. I’m especially looking for pics of fungal infections, Mildew and pests like Nematodes, Witches Broom etc. It’s definitely possible that this book will get a printed release at some point, but for now we’ll roll it out as an eBook and see what happens.
Despite the fact that this book took years to finish, I decided to publish TRICHOCEREUS CULTIVATION free of charge. It’s my gift to the community ! As someone who was broke af for quite long I know how it feels to miss out on expensive books and I wanted to create something that everyone can access freely and enjoy. I’m happy that it’s finally done now. I had a terrible health season, and it took a lot of pain to get it done. Needless to say we didn’t have the same editing budget we have for the printed books, so please treat errors as something that we’ll fix in the next edition. We will constantly edit around and fix errors and changes on the fly. Thanks a lot to Liam Engel for the editing help. Couldn’t have done it without you.
So yeah, this is it! 😊✌️

Despite the fact that I mostly publish printed books, I like the eBook as an art form and it was always my plan to write an eBook at some point in my life. The hard copy cactus books I´ve published are not cheap and it was important for me to publish something that everyone could access and afford.

There were many times in my life when I struggled financially and I know very well how it feels when you cannot afford something you´d like to have. Because of this, it is not really my plan to earn a lot of money with my TRICHOCEREUS CULTURE eBook. Right now, the plan for this eBook is to either give it away free or sell it at a price that´s so minimal that everyone will be able to afford it. It really is important to me that these books get to the community and making money is not the plan here. I still need to make sure I am not going broke during all my projects and if you want to support me you can do that via or by buying stuff from our website at Please consider subscribing to my newsletter and engaging and sharing my content online.

It took a long time to complete this book and it will be updated on a regular basis. TRICHOCEREUS CULTURE is an extensive guide, useful for all cacti growers out there. This is not a completely and professionally published book and I want to point that out! While this eBook may not be perfect, it will help people all over the world and we will constantly edit this eBook with new stuff, photos or corrections.

After publishing this eBook, I am working on the third and final volume called THE GENUS TRICHOCEREUS. This book is shaping up to be massive, with over 500 pages and a complete revision of the genus. As there were some problems with American Crowdfunding services during my campaign for the second book (these service didn´t like the genus Trichocereus), we will probably only print a very limited run via preorder and if you want to get on the preorder list, make sure to email me via

If you want to donate photos for the book or just share your thoughts please send me a message. I am always happy to help. So yeah, this is it! Enjoy the book!

Best wishes, Patrick Noll
