About Us

How did TOPBUXUS start?

In 1987 Adrie van Dun and his father Janus, owners of a family business in the tree nursery sector, decided to focus entirely on growing and trading Boxwood.
Under the brand name TOPBUXUS they started planting 30,000 rooted Boxwood Sempervirens cuttings. Until 2011 we have grown a total of about 12,000,000 Boxwood plants on 50 hectares in Strijbeek, the Netherlands.

Where did all these plants go?

Mainly to large plant import and export companies and retail garden centre chains all over Europe.

How was research done?

Our knowledge of effective growing methods has been developed through continuous testing in our own nursery. In 2000, TOPBUXUS was asked to conduct field trials in collaboration with the Dutch government.

The aim was to explore soil improvers that could support the vitality and resilience of Boxwood. We began analysing the nutritional needs of Boxwood and evaluating the impact of various organic and mineral fertilisers. At the time, we used the individual components now found in HEALTH-MIX alongside standard nursery practices.

Boxwood Health

By 2008, new challenges began to affect the condition of Boxwood plants more widely. This spurred us to develop a user-friendly product for home gardeners. Working with Wageningen University in the Netherlands, we conducted a series of trials to determine the ideal composition and frequency of application for our formula. The goal was to create a well-balanced supplement that supports healthy growth and nutrient uptake.

The result was an effervescent tablet that enhances water quality—making it easier for plants to absorb nutrients. Lab trials were conducted under challenging environmental conditions, such as high humidity and warmth, to simulate stress situations for plants. These studies indicated that, during the growing season from May to November, a monthly application provided consistent results in supporting overall plant health.

In July 2011, the TOPBUXUS HEALTH-MIX effervescent tablet was introduced in Europe and received a positive response. In 2019, it became available in North America under the name TOPBUXUS BOXWOOD RESTORE & PROTECT MIX.

Following the success of this product, a year later we introduced our TOPBUXUS BOXWOOD TURBO GROW, a fast acting granular fertilizer scientifically developed and made just for Boxwood. This fertilizer helps Boxwood root development and improves the quality of growth all season long. It also helps stop yellowing and orange leaves.

Both products used in conjunction ensure healthy and vigorous plants.
