I often see posts asking what’s the best forage for horses? This really depends on your geographic climate. My horses thrived on native grasses in eastern Washington and Idaho, living mostly on pasture with some free-choice minerals, only given hay in the winter and rarely given any grain unless one was old and needing the extra support or just as a treat. Most of our horses lived well into their 30s like this with regular riding throughout their entire life. After moving to the Midwest, I noticed monoculture pastures were more common, often paired with heavier supplementation. That made me curious why different regions manage pasture so differently.
The “ideal” pasture isn’t just one grass. It’s a combination of diverse species, regionally appropriate native plants, proper grazing height, and attention to maturity. In many areas, a strong base of cool-season grasses like Timothy, Orchardgrass, and Kentucky bluegrass provides steady fiber, moderate protein, and consistent energy. Native grasses and herbs can add deep roots, strong soil structure, excellent fiber, more reliable summer grazing, and in some cases, medicinal or symbiotic properties that support the local ecosystem or needs for that particular environment. Always remember not all native species are safe for horses. Although horses are pretty good at detecting what plants they can and cannot eat, new environments or environmental stress like drought or overgrazing can change availability of what your horses are used to and make them eat plants they generally wouldn't forage for. I highly recommend reading "The Village Horse Doctor" by Dr. Ben Green for some examples of this.
Grass height matters for sugar management. Ideally, start grazing at 6–8 inches and remove horses at 3–4 inches. Short, stressed grass can spike sugar (NSC) levels, and lush spring pasture can also increase sugars, especially in sunny afternoons after cool nights. The time of day also matters. If horses are only allowed to graze at certain times of day like late afternoon, this tends to be when sugar is highest. Dry, mature native forage is excellent for easy keepers or insulin-resistant horses, offering more fiber, thicker stems, slower intake, and gradual energy release.
Monoculture isn’t healthier for our horses or our environment. Horses, like us, thrive on variety to get everything they need. Plants often labeled as “weeds,” like dandelion and broadleaf plantain for example, can be nutritious and supportive. Allowing diversity supports metabolic balance, digestive health, mineral variety, long-term soundness, and soil health. The “best” pasture isn’t the greenest; it’s the one that offers variety so your horse can select what it needs for your climate and based on its individual needs.
Below is a picture of my horses when we were in eastern Washington at their home of almost 20 years and they lived purely on pasture the majority of the year with access to some free choice mineral for that particular environment. They were all basically free range and never were restricted in what they could or couldn't eat or what time of day they could graze, and they could absolutely figure it out themselves. They avoided the high sugar grasses during the hotter parts of the day, but enjoyed them in early morning when sugar was lowest. The tobiano paint was an older horse in need of a home that was pretty new to us but had been on pasture only her whole life as far as we knew. The gray is in her late 20s in all of these pictures and had always lived a pretty natural life like this. They were still all ridden frequently up to 15 miles a day a few times a week, and they were typically happy to meet you at the gate for a ride or showed up shortly after calling out to them. If they didn't want to go, you couldn't even find them in their pasture, which particularly only happened during the hottest parts of summer. Sure enough, they would turn up as willing partners once the day cooled off. I find it important to listen to the horse to ensure they enjoy the activities as well. In doing so, you'd be surprised how great of a partner they become. The more they have from nature, the less they need from you; however, if you have a good relationship with your horse, it should not be based on them needing you.
Horse management is very geographically dependent, yet I often hear people judge others based on their own regional standards. Remember that every environment is different. Your practices should reflect your local climate, soil, and pasture conditions. Learn as much as you can, but always consider whether the advice you’re following is coming from a region or situation that truly applies to your horses. And of course, always listen to your horse. They typically know their needs better than we do and can tell you a lot. ❤️
