Dekker Chrysanten's African branch in Moshi, Tanzania, at the foot of Kilimanjaro, is the company's largest overseas location. Two farms also operate in Arusha. Depending on the season, the sites employ 800 to 900 staff in total. These staff members mainly focus on propagating chrysanthemum cuttings that are supplied to chrysanthemum growers in the Netherlands, other European countries, and South Africa.
The company in Tanzania has significantly improved its sustainability credentials by installing LED lighting and a biomass boiler that burns the residual waste from coffee beans. Dekker Chrysanten is actively working to improve the lives of local people: employees enjoy more than standard terms of employment and health care insurance, which also covers their family members. By setting up its own Dekker Chrysanthemum school, the company is also doing a great deal to help young people in the country develop.
