We are aware of the adverse effects of car pollution on health. If you are living near a main road, or a road which has become busier and car pollution concerns you, there are steps you can take to ameliorate the effects. We have long known the benefit of trees and know scientists have discovered that hedges can be used to help improve air quality alongside urban roads.
Trees do absorb pollutants, but hedges are physically lower growing as they do at car and traffic level. Research by the University of Sussex and from the RHS, has also determined which hedges are best at absorbing pollutants. Certain shrubs, predominantly those with larger leaves, rough or hairy leaves trap the most pollutants. Ideally to be most effective the hedge needs to be 1.5-2m high and a density of 1m.
Recommended shrubs to plant for the purpose of absorbing pollutants by creating a green barrier include : Cotoneaster, Hawthorn, Cupressus macrocarpa, Elaeagnus x ebbingei, Common Beech, English Yew, and Viburnum Tinus. These are both evergreen and deciduous shrubs and would make an attractive mixed hedge or a simple line of Common Beech, (Fagus sylvatica) can look very stylish and help to soak up pollutants. There are more illustrated below.
Mix and match the shrubs below to make a varied and interesting hedge which is colourful, interesting to the birds and will help clean up the air around your home.
