A well-maintained garden can significantly boost a property's appeal, but certain invasive plants may deter buyers and slash thousands off your home's value, according to property specialist Karl McArdle, co-founder of The Property Buying Company.
Arrow Bamboo: A Spreading Threat
Arrow bamboo is a tough, spreading evergreen that can reach up to six metres in height. McArdle warns that in warm, moist conditions, its creeping rootstock produces new shoots away from the original plant, causing it to spread uncontrollably. If it encroaches on neighbours' fencing or near drains, it could reduce your property value by 5 to 15%.
Leyland Cypress: Fast-Growing Nuisance
This large, fast-growing evergreen tree can reach up to 30 metres if left unchecked. McArdle recommends regular trimming to keep it under control. If it overshadows other plants in your garden, it could knock up to 15% off your property's value.
Russian Vine: Vigorous Climber
Russian vine is a woody, twining climber that can grow up to 12 metres tall and spread eight metres wide. Without proper pruning, it quickly becomes too large for an average garden and can cause damp issues. Minor damp can devalue your property by up to 10%.
Lombardy Poplar: Subsidence Risk
This large, narrow tree can reach 30 metres in height. Its vigorous root system poses a significant subsidence risk if planted near a home. A history of subsidence can slash a property's value by as much as 25%.
While Japanese knotweed is well-known, these other invasive plants can also cause costly damage. McArdle advises homeowners to identify and manage these "garden thugs" to protect their investment.
