🌾 It’s that time of year! Stocking up and storing hay for winter is an important investment, so don’t let your hard-earned hay wither away.
☔️ Cover Outdoor Bales – Use a tarp or durable plastic cover to cut storage losses by half. For round bales, net wrap or B-wrap protects better than twine.
🐁 Water & Animal Proof Your Storage Site – Avoid stacking hay under a leaky roof, which can lead to mold. Plug rodent holes and keep out wildlife — they can move in for the winter and make a mess. F***s from some wildlife can spread diseases to horses.
🪜Keep Hay Off the Ground – Store indoor and outdoor bales on pallets to allow air flow under the bales and help prevent moisture absorption from the ground. Hay stored on wet ground can cause up to 50% spoilage.
⏰ Use Older Hay First – Properly baled and stored hay can last indefinitely, but should be fed within two years of harvest. High humidity and temperature swings can increase the moisture content of hay and reduce its storage life.
🌳 Store Round Bales Smartly – When storing outdoors, place round bales end to end and do not stack them. Stacking round bales stored outdoors can increase losses by trapping moisture and limiting drying from the wind and sun. Avoid storing bales under trees or in low-lying areas.
