Hello there! I've searched up several poisonous plants pages available on the web where it concerns horses, yet my sister-in-law next door has a particular question for her ponies.
I wasn't sure how comprehensive some of these lists were (though this one looked pretty thorough), and she was wondering if it would be safe for her to plant a kiwi vine and boysenberry along a fence row where her ponies graze. They don't bother her clematis or honeysuckle vine, so she wasn't sure if, a: that she should worry if the kiwi and boysenberry is poisonous, or, b: if the ponies would take a liking to the leaves of either plant, should they be non-poisonous, and strip/kill them.
They love to get a hold of mulberry branches when they're available for their (apparently) tasty leaves, and weren't sure if there might be a similar problem here. She wants to be sure the kiwi and boysenberry will survive.
My guess is that since I cannot find any reference to either of these plants being poisonous, the danger is that they will find one or both particularly tasty (especially given their enthusiasm with the mulberry leaf) and she'll have to replant somewhere else.
Anyone have any experience with these plants in the vicinity of horses? Help is much appreciated!
