Invasive species could be draining your wallet; experts advise immediate action

A well-kept garden is not only a source of pride and joy but can also significantly increase the value of your home.

However, it's not just about keeping the lawn mowed and the hedges trimmed.

The plants you nurture in your backyard could substantially impact your property's worth, especially if you're considering putting it on the market.


Recent research has highlighted a green thumb caution: while they may seem harmless or aesthetically pleasing, certain plants could silently reduce your home's value.

Poorly manicured gardens with the wrong types of plants could lower a home's worth by a staggering 30 per cent.

Property expert Shaun McGowan has shed light on this leafy issue.

He advised homeowners to be particularly wary of invasive species that can cause structural damage to walls, drains, and foundations.

'With plants like weeping figs and ivy, which can cause costly structural damage, homeowners should seriously consider removing these invasive species if they’re planning to sell,' he said.


So, which plants should you be wary of? Here are the five main species considered the biggest threat to Australian home prices:

Weeping Figs, despite their popularity, these trees have invasive root systems that can infiltrate pavements, underground drains, sewage systems, and even swimming pools.

Agapanthus are found nationwide; this plant can spread rapidly via its purple flower, which can self-reproduce.

Palms add a tropical ambience to a garden. Their root systems can be damaging as they grow, potentially invading walls, foundations, and pavements.

Recognised as a severe environmental threat in several states, ivy is an aggressive invader that can cause damage within just one or two years, even toppling large trees.


The cost of professional removal of these plants can run into the thousands.

Still, McGowan warns that leaving these species unchecked may lead to repair costs that far exceed the expense of professional removal.

'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.

It's not all doom and gloom, though. Good landscaping can add up to 28 per cent to a home's overall value.

Conversely, a neglected garden could lower a property's value by 5-15 per cent, with some real estate agents believing the effect could be even higher.

As an ivy loving person, I keep all my ivy type plants in hanging baskets and they go nowhere near brickwork, fences or the ground. As we get older, we are being asked less often, to deal with extended family issues with palms and by brother has given up tree felling so he's also no longer having to deal with the problems people who "don't know" end up with.
 
I have a hidden tropical garden behind my vegie garden which I have a couple of palms.

I get very nervous when we are having severe storms and seeing one in particular swaying.

We also have Agapanthas in Orange and red . They are under control and really beautiful.
I only commented to hubby yesterday while at flower power how expensive they are

I love ivory especially the variegated varieties , we do however have them all in pots

The trees I definitely stay away from is Oleanders . We had three of them when we purchased our house and hubby dug them out straight away , only because it's deadly if consumed

I have never had any problems with agapanthus at my home.
After flipping homes for many years I am obviously aware of the increase in value a well maintained garden can add to a property
What amazes me is the number of people who purchase our homes and then do not upkeep the gardens, it appears as if they think a garden looks after itself.
Driving past one of our properties recently, which had actually been our own home, not a flip, it broke my heart to see what had been a beautiful garden now overgrown with three foot high weeds, dead plants, etc. It looked like the city dump.
The value of that property would have depreciated considerably.
