In the summertime especially, I take my students out on regular trail rides. Part of their lesson is to learn and identify which poisonous plants are on the trails. We frequently come across bracken fern, tansy ragwort, horsetail, creeping buttercup, St. John's Wort, cherry trees and foxglove.
I have oak trees nearby my barn. I don't have my horses at my house yet, as we are still preparing for them. Should I be worried about the leaves dropping into the fence and them accidentally eating them? There will be grass for them to graze on and I'd hate for them to get sick. Should we take the trees out or just make sure we leaf blow when they start to fall off the trees? Thanks!
