Our Precious People

Erika Oberholzer


CEO

 

Erika Oberholzer, named the Female Farmer of the year (2006), is a farmer and philosopher from sunrise until sunset. She is the CEO of PicoGro edible flower farm – her baby and brainchild. Erika’s formal training occurred in a diverse range of subjects including Botany, Biochemistry, Project Management, Moral Philosophy and Graphic Design. After spending her 20’s in a laboratory environment where she worked as a Biochemistry technician at the Agricultural Research Council in Irene, she sought to create more and use her wide range of skills, which resulted in the creation of PicoGro.

 

Erika spends her days overseeing all the agronomic activities on the farm, developing new products, and watching the PicoGro management team blossom. PicoGro has a strong team of young woman (and men) that are responsible for the day-to-day activities on the farm and has, for the past 8 years, been doing an exceptional job of lightening her load.

 

She recently started work on a PhD in indigenous plant use at the University of Johannesburg and plans on spending more and more time with her books, that were her first love.
