Our roots run deep in the soil of the southeast. For over 140 years the Denne family has been trading as T Denne & Sons, serving growers across the region since 1879.

We’ve been processing grass seed since 1935, building a reputation for quality and consistency through generations. Now led by the fifth generation, our family business continues to evolve while honouring the traditions that define us.

Today, we are proud to be one of the UK’s leading independent grass seed processors, processing and packing British-grown grass seed, and supplying high-performance mixtures for agriculture, landscaping, conservation, equine, and amenity use.
