A prospective homebuyer was left disappointed after discovering a potential environmental nightmare while touring the backyard.

A Reddit user posted a photo in the r/GardeningUK subreddit with the caption: “Hi, I viewed a property today and i’m 99% sure it has Japanese Knotweed in the garden. Can someone confirm please?”

Unfortunately, the original poster had their worst fears confirmed, as commenters verified that the plant was featured in the photo was japanese knotweeda notorious invasive species that is known for its rapid growth and potential to overtake native plants after spreading from neighboring yards. Like most invasive speciesJapanese knotweed can outcompete native plants for resources such as sunlight and nutrients and can lead to a decrease in biodiversity and thereby harm the local ecosystem.

Commenters didn’t mince words when warning the OP of the dangers of Japanese knotweed and recommending that necessary steps be taken to evaluate the yard before moving into the home.

“I used to deal with this. I wouldn’t go near the property,” one commenter wrote. “If that’s a boundary fence, then the actual root could be on the adjacent property. Therefore, it’s their responsibility. Before any further viewings, there should be a survey.”

Invasive species can be difficult to control once established. In some cases, plants like bamboo life damage foundations or other parts of homes and buildings.

Before making any decisions on buying homes, it can be helpful to consult with a local expert or a landscaper who has experience dealing with invasive species. As some commenters recommended, you would be within your right to require the seller to take care of the issue before purchasing the property.

“You can request that the seller pay for an eradication plan as a condition of sale — we did that and it’s all been fine,” one commenter stated.
