Gardeners in Hexham are being urged to avoid choosing invasive plants that can spread into the wild.
The warning comes as the country enters the hedge planting season.
Daniel Docking, Invasive Weed Control technical manager for the Property Care Association (PCA) voiced his concern and pinpointed two ornamental species, Cherry laurel and Japanese rose, as particular menaces.
Mr Docking said: "Our advice to gardeners is to be particularly careful about the plants they choose for landscaping projects as the UK enters the traditional hedging season.
“Invasive species such as Japanese knotweed and Giant Hogweed are regularly in the headlines, but PCA members’ work embraces all aspects of invasive non-native plant control, and we are concerned about the impact of Cherry laurel and Japanese rose."
The PCA said these species not only spread rapidly but also disrupt the ecosystem and impede biodiversity.
Mr Docking added: "Gardeners can play an active role in controlling the spread of these plants and other invasive non-native species.
"Our advice is to seek expert advice and choose plants that are not going to overpower and dominate their natural surroundings."
