Feedback and comments from participants on the seminars


The seminar was very well prepared and well attended, the catering was, as usual, excellent, and Dr. Thumm once again proved to be his characteristically entertaining and good-humored presenter. I was able to have several interesting and insightful conversations. The integration between planners and executing companies works very well at your events. Particularly noteworthy is the fact that there are hardly any other seminars where the different types of metals and surface finishes are defined and explained so clearly. By this I do not necessarily mean CORTEN steel, but especially the less “hyped” metal surfaces for use in outdoor spaces.

Thomas Krieg, Freier Garten- und Landschaftsarchitekt, 75239 Eisingen

The seminar was fantastic, incredibly informative, and thoroughly engaging, and it answered all my questions, allowing me to recommend Gartenmetall with complete confidence. I work for two gardening and landscaping companies, and I’m the one who handles the initial contact with customers. This is followed by planning and selecting samples, and of course many discussions with the customers. For me, providing good, honest advice and ensuring customer satisfaction are top priorities, because the customers trust me. Gartenmetall’s philosophy makes it easy for us planners and contractors to be recommended to others, since everything runs smoothly. And if there’s ever a snag, Gartenmetall looks for solutions... This seminar has greatly expanded my foundational knowledge and helps me present myself as a competent professional. This makes clients feel well advised.

Ute Eichhorn, Garden Designer, 55270 Jugenheim

We had the opportunity to experience many interesting projects up close—the behind-the-scenes look at production was fantastic! The very pleasant conversations with the gardeners, landscapers, and Gartenmetall staff made for an entertaining day. In addition, the presentations and catering were top-notch. We’d be happy to visit your facility again if you hold another event.

Alexander Schöller, eichenlaub schöller architekten, 71384 Weinstadt

Gartenmetall struck me as incredibly authentic and down-to-earth. Mr. Thumm did a wonderful job of capturing the essence of the products. I arrived full of anticipation, and my expectations were fully met. I also had some exciting encounters. I’d love to come back.

Jutta Bechtel, Gartenwerke, 67240 Bobenheim-Roxheim

Mr. Thumm described and demonstrated the products with great passion. It was a very impressive day, even from a technical standpoint.

Gerd Oczko, Planungsbüro Gerd Oczko, 63110 Rodgau

Entertaining, informative, and engaging—that’s the best way to sum up the day at the technical seminar. As installers, it gives us a good feeling to work with manufacturers who are so committed to their product and have such high quality standards. You made your constant refinement of design and craftsmanship come to life for us that day. Ultimately, this complete package also makes our work easier. Thank you for that, and keep up the great work!

Oliver Mannsperger, Horticulture, 76689 Karlsdorf-Neuthard

We at GRÜNWOLF attend Gartenmetall’s seminars every year because we want to stay up to date on the latest technology for our customers and offer the newest innovations in metal garden products. At these seminars, the latest products, improvements, and optimal installation methods are presented, along with tips on how to avoid mistakes. This ensures we’re always well-prepared for the coming gardening season. We highly recommend Gartenmetall’s products and excellent service and will continue to expand our selection of Gartenmetall products.

Alex Lemon, GRÜNWOLF

Thank you for the seminar I had the opportunity to attend today in Essen. It was very well organized, and I gained a lot of new insights, especially about Corten steel. For example, what I, as a landscape gardener, need to keep in mind during installation and maintenance. I also came away with many new ideas, suggestions, and new products for designing existing or new gardens.

Louis-Marie Guillet, LHG-Garten

The seminar in Wetzlar that I attended was great and very helpful on certain topics. 

Sebastian Haeder, Garden Design and Maintenance

Thank you very much for this insightful seminar on the topic of metal. Mr. Thumm’s self-critical approach and his sharing of practical tips and legal considerations were very interesting.

Joshua Schotten, Schotten the Gardener

This critical approach to its own products and the materials used in them shows that Gartenmetall is genuinely interested in finding good solutions—and isn’t just trying to sell as many products as possible as quickly as possible, products that merely look good. European consumers need manufacturers and artisans who take pride in their work and products (even if that comes at a price). The environment needs durable, solid products—not cheap, disposable junk. 

Thomas Weilinger, Garten Weilinger

The seminar in Hörstel was very informative for me. I picked up quite a few details from Mr. Thumm’s engaging presentation that will certainly help me in my day-to-day planning. 

Michael Krüger

Mr. Thumm’s lighthearted and refreshing style made the seminar very entertaining, and we were able to take home many practical tips. 

Rainer and Niklas Kellermann, Neubauernhof

Although I was already familiar with the products “in theory” from the catalog, it was quite another experience to “see them in person.” Add to that the explanations from the boss himself—that really deepened my understanding of metal in the garden. I also appreciated the honest explanations of the issues that can arise if the products are used incorrectly. All in all, very informative and inspiring! I can already see opportunities to use Gartenmetall products for my clients! 

Harald Lebender, Gardens for the Soul

Mr. Thumm led the seminar in a practical and honest manner in a pleasant atmosphere. 

Thomas Nellessen, Nellessen Garden Design and Path Construction

Thank you very much for the very informative seminar in Hörstel. The day was very interesting; the balance between theory and practical tips was just right, and it was easy to follow. The care instructions will certainly help me in conversations with customers and ensure a long service life for the products. 

Mona Funke, Planten und Plaastern Garden and Landscaping
