We were set up in 1997 by DH Horticultural Developments Ltd and Keith Pegden Agricultural Contracting, to supply M-Trays® to Wallbarn to meet their rapidly increasing demand for a modular green roof tray system.
DH Horticultural Developments is an R&D company, specialising in seed mat, green roof and novel growing systems. Keith Pegden Agricultural Contracting provides the heavy machinery needed to handle the thousands of tons of compost and tens of thousands of the high quality M-Trays® needed by Wallbarn to supply industrial and domestic green roof customers.
We work closely with Wallbarn, providing technical assistance and product development to ensure all safety and performance requirements are met. All components used, including the M-Tray® are from recycled or sustainable resources. Our compost is peat free, has been rigorously tested by The STRI Group and meets all the requirements of The Green Roof Organisation (GRO Code).
A mix of 13 sedum species supplied by Jelitto, form the basis of our production, giving outstanding benefit to wildlife with a prolonged flowering period. Sedum is one of the very few plant groups that can survive the exposed and hostile conditions encountered on a roof. M-Trays® provide optimal water retention and help cope with the extremes of drought, temperature and water runoff. The M-Tray® design allows for rapid installation and easy maintenance.
M-Trays® can be supplied in combination with native wildflowers. These require a much higher level of annual maintenance and replanting in order to achieve a positive outcome. Fire risk is a serious consideration, especially when including annual wildflowers in the mix.
A well maintained green roof will last many years and often out performs roll-out sedum alternatives. Many of our installations replace poorly maintained roll-out sedum green roofs which have failed to withstand the extremely challenging conditions in this tough exposed environment.
Sedum Growers also manufacture seed mats for weed control which are distributed
We are based in North Hampshire, within easy reach of the majority of customers for green roof supply, installation and maintenance.
We are proud to maintain a collaborative approach to the whole business. Each team member has a direct input into the key decision making, the growing of crops and ensuring the quality of our products and customer service.
Valuable knowledge and industry support is provided to the Sedum Growers business from the following three consultants.
The majority of our green roof business is through Wallbarn and their customers. You can also find the seed mats we manufacture for G Plants in garden centres and retail outlets.
We also provide M-Tray® installation and maintenance. (Insert link to Sedum Growers’ Installation and Maintenance Service website page/online enquiry form).
