A beautiful estate on the Roseland in Cornwall with a hidden industrial history

Growing specialist crops to benefit well being

A working environment committed to replenishing the landscape

The Trelonk Story
Trelonk is a beautiful farm and estate close to the banks of the tidal River Fal, in the heart of Cornwall. At Trelonk we are harnessing new technologies and sustainable farming practices to grow calendula (marigolds) and other specialist oil seed crops that can be used as ingredients for health and wellness products.
Trelonk Farm has diversified its cropping and its approach, utilising scientific breakthroughs in horticulture and regenerative agricultural practices, allowing us to offer a truly environmentally responsible product to the wholesale market.
All of our products are fully traceable to our single origin in Cornwall. The estate has been farming for generations – and will be for many generations to come.

What we are farming
We are farming nutrient dense oil seed crops to create specialist oils for use in nutraceuticals, cosmetics and other wellbeing and health products. In addition to calendula, our crops include borage, sunflowers, camelina, roses & mustard.
Growing and processing through cold pressing on site ensures full traceability and authenticity of the products, governed end-to-end by our strong environmental credentials.
Our plant based ingredients are not only high-quality, but come with a compelling backstory that will differentiate your end product from those of competitors. Soil to oil no additives!

country stewardship scheme
We are working towards a Mid-Tier stewardship scheme beginning in 2020.
The aim is to deliver significant and accountable ecological gains for the local environment, from the provision of new habitat and sustenance for wildlife to the protection of important water courses and the improvement of air quality.
Here at Trelonk, we have many landscape features that deserve protection and maintenance due to their cultural and historical significance.
The scheme also us to preserve and protect our hedgerows, woodland and water courses for generations to come.
