Australians are being warned the presence of certain plants on their property could decrease its value if they're considering selling, with research revealing poorly manicured gardens could lower a home's worth by up to 30 per cent.

While some plants can be an asset to a home, other types could be putting its value at risk, particularly when it comes to those deemed invasive. Property expert Shaun McGowan spoke to Yahoo News Australia and warned homeowners of the types to avoid if they're looking to sell.

"With plants like weeping figs and ivy, which can cause costly structural damage to walls, drains, and even foundations, homeowners should seriously consider removing these invasive species if they’re planning to sell," he told Yahoo.

There are five main plants across the country that are considered the biggest risk to Australian home prices. Weeping figs are very common and can become problematic if planted in gardens, due to the fact they have invasive root systems which can infiltrate pavements, as well as underground drains and sewage systems — and even pools.

Agapanthus, which are found all over the country, can also be highly invasive. This plant can spread very easily via its famous purple flower, which has the ability to self-reproduce.

Palms are another Aussie favourite that add to the ambiance of a garden, though their root systems are damaging. As they grow, they could invade surrounding walls, foundations, and pavings.

Similarly, Ivy is also recognised a serious environmental threat in several states, with it only taking one or two years for damage to be caused. It is an aggressive invader, even capable of toppling large trees.

McGowan, of mortgagebroker.com.au, said left unchecked these species may require a specialist to attend a home to have them removed.

"Plants like these not only threaten property value but can lead to repair costs that far exceed the expense of professional removal," he said. "Addressing these issues proactively can help homeowners preserve their property's value and avoid unforeseen costs."

Recent research suggested good landscaping can add up to 28 per cent to a home's overall value, while an additional study found 70 per cent of real estate agents believe a neglected garden could lower a property's value by 5-15 per cent, with 17 per cent believing the effect could be even higher.
