History

The History of Rhizopon – Rooted in Amsterdam, Growing Worldwide

1930s – The beginning: rooting innovation at ACF

Rhizopon’s origins trace back to the 1930s, when the first rooting products were developed at ACF (Amsterdam's Chinine Factory). These early innovations laid the foundation for decades of expertise in rooting hormones.

1987 – Foundation of Rhizopon as an independent company

Following a company reorganization in 1987, ACF decided to divest its activities in plant growth regulators. This led to the founding of Rhizopon B.V.—a fully independent company with no further ties to the former parent organization.

What remained was a deep and growing body of knowledge on how to apply rooting hormones effectively in a wide range of crops.

1990s to today – Supporting growers through research and innovation

From its establishment, Rhizopon has prioritized collaboration with growers and researchers. The goal: to improve the rooting process across many cultivars using Rhizopon products.

This close cooperation has led to new insights, refined techniques, and application methods that align with modern developments in young plant production.
