Diebold & Zgraggen Gartenbau AG

What Diebold & Zgraggen Gartenbau AG does

Diebold & Zgraggen Gartenbau AG is a Swiss garden construction and landscaping company headquartered in Fislisbach, Canton Aargau, founded in 1995 by Alain Diebold and Peter Zgraggen. The firm operates an end-to-end garden lifecycle model: fixed-price garden planning (consultation, design proposal, execution plan, planting plan), turnkey garden construction, and recurring maintenance. Specialized service lines include automatic irrigation (rain-sensor and app-controlled, ~25 years of installed base), biothermal/ELMOTherm hot-water-foam chemical-free weed control, surface cleaning, lawn-mower sales and service, slope mowing (up to 55°), playground safety inspections, green-roof inspections, and court-grade expert opinions delivered through Jardin Suisse certification.

The business employs roughly 60-70 staff, has trained 71 apprentices since founding (an above-industry apprenticeship rate above 10%), and operates a wholly-owned subsidiary, Skygardens AG (est. 2022), focused on building greening, roof and facade systems, biodiversity, rainwater management, and sponge-city concepts — extending the residential-gardens franchise into urban climate-adaptation infrastructure.

Revenue is generated primarily through professional-services contracts with private residential customers (planning, construction, ongoing maintenance), supplemented by municipal projects (e.g., Kreisel Staretschwil redesign for Oberrohrdorf) and commercial greening engagements. Pricing is fixed-price for planning packages and project-based for construction, with a customer self-service portal (fm.dzgartenbau.ch) for ongoing maintenance clients. Distribution is direct-field with regional concentration in Canton Aargau; marketing is built on an Instagram presence (~1,269 followers), YouTube, blog/press coverage (SRF Schweiz Aktuell, Aargauer Zeitung, Reussbote), and earned recognition including the ZKB KMU-Preis 2019 (2nd place for sustainability), Gärten des Jahres 2017 (two featured gardens), and multiple Giardina Gold/Silver awards.
