About us

How did Topbuxus start?

In 1987 Adrie van Dun and his father, Janus, proprietors of a conventional family tree nursery business, decided to branch out into Buxus. 

Branded Topbuxus, we planted 30,000 rooted Buxus Sempervirens. By 2011, we had nurtured 12.000.000 plants on 50ha in Strijbeek, The Netherlands. 

Where do all these plants go to?

Primarily major plant import-export companies, garden retail centres and DIY garden chains.

How did we go about research?

The key to successful growing solutions is through continuous testing.  In 2000, Topbuxus was asked to conduct field trials on behalf of the Government. We set out to evaluate the plant's intake and the action of organic and mineral fertilizers, to find soil improvers that raise the resistance of the plants but also to find ways to cure and prevent fungal diseases. At that time, we used the loose components of HEALTH-MIX combined with traditional fungicides in the nursery.

Box blight

In 2008, Box Blight started to have a negative impact on the Boxwood industry. This was the trigger for us to find a way to develop a, product available for the consumer. With the University of Wageningen, we carried out numerous experiments to determine the correct dosage of different components and the frequency of treatments needed to control the fungal diseases. The resulting balance of the different ingredients was then presented in an effervescent tablet. The components have disinfectant properties and they also soften the water, which facilitates the absorption of the various components by the plant. The laboratory tests were carried out in the ideal environment for the fungus to thrive - humidity and heat, sealed in. Results showed that during the 'fungus-season' from May-November, a single treatment per month is sufficient to survive the worst "fungus weather conditions". In July 2011 the HEALTH-MIX tablet was launched.

Four years ago we decided to stop using fungicides. Unique in the world of Boxwood nurseries.
