Rhododendron warning after experts claim plant is invasive

Rhododendrons became popular during the Victorian period and it was widely planted as a garden ornamental. However, this invasive shrub spreads very quickly by prolific seeding and then

layering of branches. This eventually forms a closed canopy on top of woodlands, blocking out the light. The Woodland Trust has warned that the plant can spread fast and crowd out native

plants in woods. This is threatening the UK’s rare temperate rainforests and costing millions to tackle and Britons are being urged to “avoid” buying the plant. Rhododendron ponticum is the

only species of rhododendron which is considered to be an invasive weed, and avoiding planting it is strongly recommended. There are hundreds of other species and varieties of the plant

which make for far better garden plants, without the worry of spreading into the wild. Whilst you are unlikely to find this variety readily available in garden centres, it is encouraged to

double-check the variety before planting it in your garden. Rhododendron ponticum is listed under Schedule 9 of the Wildlife and Countryside Act of 1981, which means it is illegal to plant

it in the wild or to allow it to spread from your property. Any pruning or waste material from this plant must be disposed of responsibly and appropriately. This is extremely important

because it is not only toxic to people, it also contains toxins harmful to livestock. If you think you may have this species in your garden, it can be identified by its woody stems which

eventually form tree-like trunks. They have large leaves which are lance-shaped and produce large trusses of flowers in the early summer, typically in shades of purple. Another invasive

plant which can result in many problems is Japanese knotweed, recognised by its heart-shaped leaves. Eradicating knotweed is a long-term battle and although Britons can attempt to tackle it

themselves, it is recommended to enlist the help of a professional. If you do decide to start tackling it, Harry Bodell at PriceYourJob.co.uk, recommended using a herbicide treatment. Using

this should be during the spring or autumn when the plant is actively growing, making sure to completely cover the leaves.
