I'm planting some trees next to neighbors with horses and cows. Eventually the fruits and leaves will reach their yards. As far as temperate and subtropical fruits/nuts, what's safe and what's beneficial? I've done a bit of searching and it seems that horses will like Carob and the leaves of Mulberry. Walnuts are a no-no. So is Bay Laurel. Most fruits not recommended? It looks like syzygium is ok, maybe even beneficial. Cloves are part of a herbal deworming product.
Other ideas?
