Question of the Week: Fruit Trees in the Pasture

Mini Horse Grazing


Q: I have a nice pasture at my house and I’m thinking about bringing home a Miniature Horse. However, my pasture has various fruit trees, including apple, fig and black walnut, among others. Is it safe to keep a horse in a pasture with trees that drop fruit, or is there any way to make it safe?

A: Fruit trees and horses do not mix, especially the types you have listed. First and foremost, black walnut trees contain a toxin that causes laminitis and although it is usually encountered when black walnut shavings are used to bed a stall, the bark on a black walnut tree may still contain enough of this toxin to cause problems in a horse, especially a miniature horse, if ingested.

Secondly, given the size of a miniature horse and the bounty produced by a single apple tree, not to mention multiple apple trees, I would not trust the mini to not gorge himself on apples, gain weight, and develop laminitis from excess carbohydrate ingestion, not to mention develop insulin deficiency from all the fructose. The same goes for figs. Therefore, in a word, no, it is not generally safe to keep a horse in a pasture with trees that drop fruit. Perhaps you could be lenient if there was a herd of twenty horses and a single apple or fig tree, but in your case, the mini is greatly outnumbered by fruit and the risk for developing laminitis, colic, weight issues, and other problems such as choke are just too great to warrant this setup.

To make your pasture safe, ideally, would be to remove all the fruit bearing trees. However, it sounds like this may not be a practical solution in your case, depending on how many trees you actually do have. If there are too many to remove, another option is to erect a fence around each tree. The logistical challenges to this fix depend on how big the trees are; obviously, the fence should be wide enough to encompass any fruit that falls off the branches. Fortunately, the mini’s height works in your favor so the fence could be shorter than if you had a full sized horse. Also keep in mind that the fence needs to have a bar low enough to prevent the mini from sticking his head through the bottom.

Another option to prevent equine access to your fruit trees is to simply fence the trees out from the pasture. Realizing this may not work if the trees are diffusely scattered throughout the pasture, again the mini’s relative size is a benefit, as the mini would not need a pasture as big as a full sized horse, allowing you to possibly fence a reasonable area in the field that does not contain any trees.

One final note on toxic trees: black walnut trees aren’t the only trees out there that are directly toxic to horses. Red maples, cherry, peach, and plum trees all have leaves that produce cyanide when they wilt. Cyanide poisoning is seen in horses that have these trees in the pasture after a storm has knocked branches down and the horses consume the wilted leaves. Black locust trees also contain toxins and acorns from oak trees are harmful as well, if eaten in large quantities.


  1. How about just muzzling the mini? There are fruit trees in my pasture and I muzzle him with the best friend muzzle and all is good 🙂

  2. We have pastures we rotate, and keep the horses out of the one with the apple tree. If the pasture is short, and we need that pasture, we do fence the tree off, with metal gates/panels. then the horses all stand and look, trying to figure out how to get an apple.

  3. I graze my mini in my orchard however I only do that when there’s no fruit for him to steal. Most of the year it’s fine! I think Tami’s suggestion of a muzzle is great. Muzzle him when the fruit is in season and the rest of the year you don’t have to worry.
    However, there is another consideration. Minis don’t need pasture 24/7 and giving him free access to grass will cause its own set of issues.
    My mini is a good weight and he’s only allowed to eat 2 hours a day on pasture during peak grass season.

  4. I keep my horses in a field with an apple tree and they do just fine. They rarely eat the fruit off the tree in the field, they prefer the apples off of our other tree for some reason.
    If you have good grass, your horse will likely prefer that, but I would watch for a couple days before taking any action to block him away from the tree that won’t do any harm.
