Jonkers hoveniers

What Jonkers hoveniers does

Jonkers hoveniers (legal entity Jonkers Hoveniers B.V., trading as Jonkers Groen) is a Dutch horticultural and landscaping services company founded in 1948, headquartered in Venlo with a branch opened in Weert in 2025. The company designs, builds, and maintains green infrastructure for municipalities, corporate clients, cultural institutions, healthcare and logistics operators, and private homeowners primarily across the Limburg, North Brabant, Gelderland, and Utrecht provinces of the Netherlands. Its service portfolio spans advisory and design through to installation and multi-year maintenance, covering corporate gardens, public green space, roof gardens (intensive, extensive, and retention systems), green facades, interior planting, private gardens, irrigation, tree care, ice prevention, and biodiverse roadside verges.

The technical foundation is rooted in green infrastructure rather than software: proprietary branded concepts include Green2Colour (perennial planting), HEEM Kruidenvegetatie (native Dutch herbaceous vegetation), RANOX Natuuraannemer (ecological contracting for fauna passages, biodiversity monitoring, and nature-based mitigation), JONK! Natuurlijk Spelen (natural play environments), and Bonte Berm (wildflower-and-bulb road verges). Specialized technical capabilities include retention roof systems, Optigrun SMART FLOW sensor-driven water buffering, mycorrhizal/organic fertilization systems delivered with Den Ouden Grow Solutions, and Tiny Forest (Miyawaki method) installations in partnership with IVN Limburg and Natuurpro.

The business model combines one-time project-based installation work with subscription-style multi-year maintenance contracts (typically 5-10 years) and standalone advisory/consulting engagements. Pricing is fully custom per project; the company does not publish standard rates but offers free advisory consultations. Sales are conducted via direct field engagement by specialized project managers, public-tender bidding for municipal work, and referrals from existing clients. Customer-visible credentials include Groenkeur certification, VHG trade association membership, BREEAM Outstanding and Paris Proof certification on the DSM-firmenich rooftop project, and a 9.0 Klantenvertellen customer-review score. Jonkers is founder-led (Director Jos Jonkers), family-owned with no disclosed external investors, and operates a subsidiary, Jonkers Daktuinen B.V., focused on roof gardens.
