Rhododendron Damages UK Biodiversity


If only deer would eat Rhododendron...

Many people have Rhododendron ponticum growing in their garden and they perceive it to be a hardy plant that looks very pretty in bloom, knowing little of the problems it can cause to native biodiversity. The fact that Rhododendron is now widespread in the wild can be attributed to its nationwide popularity and therefore its escape from gardens across the UK. This non-native plant grows in dense thickets, blocking light to native species and it uses its extensive root system to deprive its competitors of nutrients and water. In woodlands, the only plants that survive in close proximity to Rhododendron are those that are taller and therefore do not have their light blocked by the Rhododendron’s dense canopy.

In the UK, it in highly unlikely that Rhododendron spread will be controlled by natural means because the plant is neither palatable to insects nor livestock due to the presence of phenols and diterpenes in its tissue. Coupled with the plant’s ability to produce tens of thousands of seeds, the odds are weighted heavily on the Rhododendron spreading without fail.

Invasive Weeds Agency offer a solution to this problem. We can stop the spread of Rhododendron using a variety of methods that will eliminate both mature and juvenile plants. The methods we use are suitable for control of Rhododendron in any location, including sensitive areas such as beside watercourses.
