Common Toxic Trees
Red maple, black walnut, and wild cherry are among the trees known to be toxic to horses, whether through wilted leaves, bark, or fallen branches.
Toxic Pasture Plants
Ragwort, bracken fern, and certain nightshade species can poison horses if ingested, even in relatively small quantities.
Recognizing Signs of Poisoning
Symptoms vary by plant but can include colic, lethargy, drooling, or neurological signs — any sudden unexplained illness warrants an immediate vet call.
Regular Pasture Checks
Walking pastures regularly to identify and remove toxic plants, especially after storms that can bring down hazardous branches, helps prevent accidental poisoning.
