Responsibly Committed Growing strong plants.

Our company provides the vegetable production sector with a greener and more environmentally friendly solution for the currently increasing challenges with growing disease and environmental regulations. We are committed to growing strong grafted plants that require fewer inputs and produce higher yields for farmers.

Our Grafting

Grafting is a very detailed procedure whereby a growth booster (the rootstock) is combined with a promise (the scion). The actual grafting of vegetables with soft tissue stems is an extremely sensitive process, but results in a strong plant with resistance against specific soil-borne diseases.
