Cogon Grass is native to Southeast Asia, but it's found its way to America, specifically in the Grand Bay area of Alabama, where it escaped from a Satsuma orange crate in 1912.

It was later introduced in Mississippi and Florida in the 30s and 40s as potential forage and a soil stabilizer, but it didn't quite live up to its promises.

Cogon Grass is a prolific spreader and can choke out native plants wherever it grows, leading to it being declared a noxious weed and its planting outlawed.

However, it still manages to make its way around roadsides and pastures due to illegal plantings and hitching rides on equipment during road construction.

Getting rid of Cogon Grass is a challenge, but not impossible - destroying the rhizomes the grass grows out of is a time-proven method of extermination.

Tilling up the plant during the dry season dries out the rhizomes and keeps them from returning, making it a practical approach to tackling this invasive weed.

If you discover hemlock on your property, remove all animals and humans from the area and contact your local IFAS Extension for aid in eradication.

Recognizing plant poisoning in pets is crucial to provide prompt treatment and prevent serious health issues. If your pet ingests a toxic plant, symptoms can vary depending on the type and amount of plant consumed. Common signs of poisoning include drooling or foaming at the mouth, vomiting or diarrhea, lethargy or weakness, difficulty breathing, swelling in the mouth or throat, and seizures or collapse.

Drooling or foaming at the mouth is a common sign of poisoning, as the plant's toxins can cause an excessive amount of saliva to be produced. Vomiting or diarrhea can also occur, as the body tries to rid itself of the toxic substances. Lethargy or weakness is another symptom, as the toxins can affect the pet's nervous system.
