David Holloway is MD of Sedum Growers Ltd and DH Horticultural Developments Ltd. He qualified as a plant scientist from Wye in 1978 and worked for ADAS Consulting Ltd in the horticulture and food sectors as a consultant, team leader and sector manager.

In 2002, David set up a research company, with support from institutional and Angel Investors to develop and patent seed mat technologies as an alternative to herbicides for weed control in horticultural crops. The technology has been effective and commercial licences established for distribution in Europe.
