Here's why they might eat your plants:
* Grazing instinct: Horses are natural grazers and will often nibble on anything that looks edible, including your garden plants.
* Boredom: If they are bored or not getting enough to eat, they may be more likely to graze on plants.
* Lack of grazing space: If your miniature horse does not have enough space to graze on, they may turn to your garden.
Here are some tips to prevent your miniature horse from eating your plants:
* Provide enough grazing space: Ensure your horse has access to a pasture or paddock with plenty of grass.
* Fence off your garden: Use a sturdy fence that is tall enough to prevent your horse from reaching over.
* Plant horse-resistant plants: Some plants are naturally unappetizing to horses.
* Keep them busy: Provide your horse with toys or activities to keep them entertained.
* Supervise them: If you let your horse graze in your yard, supervise them closely to make sure they don't eat your plants.
Remember, horses are intelligent animals and can learn to avoid certain areas. By providing them with adequate grazing space and keeping them entertained, you can minimize the chances of them eating your plants.
