Torpedograss

Yes, it is that bad.

Torpedo grass (Panicum repens) is an aggressive, nonnative invasive grass that threatens native wetland and marsh ecosystems. University Extension research documents its ability to form dense stands, displace native vegetation, reduce biodiversity, and degrade wildlife habitat. Its extensive underground rhizome system makes eradication exceptionally difficult, and conventional mechanical removal can unintentionally spread the infestation. Effective management typically requires repeated intervention and careful protection of surrounding native vegetation.

Here are a few articles that speak to the effort required to remove it.

Mississippi State - Torpedograss.

"It is considered one of the world's worst weeds."

"Torpedograss (Panicum repens) is especially problematic in Florida where it infests thousands of hectares of wetlands, reduces wildlife habitat quality, and creates poor sportfishing habitat as it grows into dense tangled mats."

Univeristy of Florida | IFAS - Biology and Management of Torpedograss...

"Torpedograss is one of the most invasive perennial grass species in Florida landscapes."

So what?

So, the treatment of this requires a pesticide license, which River Tides does not have. If torpedograss is present, we can refer you to a licenses professional to treat, but we do not recommend planting without treatment first. Note, this treatment may take multiple years to complete.

We can try to use a very thick woven landscape fabric. It will help, but it will not stop it, nor will it prevent rooting on the groundcover above. There are no guarantees on plantings near this invasive and aggressive grass.
