The purpose built hi-tech 500sqm mist unit was opened in 2005. Over a twelve month period, approx 900,000 plants across 800 varieties are propagated from cuttings, grafts, seeds and splits. Over 70% of final plants sold by Bransford Webbs are propagated here on the nursery. The propagation unit is controlled by a computerised environmental control system to provide the optimum environment. The nursery Research and Development Unit is run from the propagation unit. Here we trial a range of new and unusual plants to ascertain whether they are suitable for the garden centre market. Through this we have introduced a wide range of successful promotions including Gazania Apache, Ceanothus Lemon and Lime, and our Hebe Red Wine and Summer Drinks collections.
