How to Store Perennial Peanut Hay Through a Florida Summer
Florida humidity is brutal on baled hay. You can buy a perfect $14 bale, store it wrong for three weeks in July, and end up with a moldy $4 bale. Here's how we keep 2,000+ bales of perennial peanut hay in barn-fresh condition through summer — and how you can do the same in a shed, garage, or open-sided barn.
The four rules of summer hay storage
1. Six inches off the ground, minimum
Concrete and ground absorb humidity. A bale touching either of them will start wicking moisture within days. Put pallets under your bales. Wood pallets are fine; plastic is better in wet zones.
2. Twelve inches of airflow on every side
Stacks need to breathe. Leave at least 12 inches between your stack and any wall, and 12 inches between stack rows. Floor-to-ceiling airflow prevents the "core sweat" that causes mold from the inside out.
3. Cover the top, never the sides
If you store under tarp (instead of a barn), tarp only the top — never wrap the sides tight. Wrapping the sides traps humidity against the bales. Use a peaked tarp or a frame that creates an air gap.
4. Inspect a sample bale every two weeks
Pull a bale from the middle of the stack every 2 weeks. Smell it. Squeeze it. Look for any musty odor, gray dust, or warm spots. Mold develops fast in July and August — catching it at one bale saves the whole stack.
What never to do
- Don't store hay on a slab in a garage with no airflow. This is the #1 cause of moldy hay we see in customer barns.
- Don't wrap a full stack in plastic. You'll cook it.
- Don't stack against a metal wall in direct sun. The wall radiates heat and pulls humidity through the bales.
- Don't store hay with feed. Mice, weevils, and grain dust all move into bales.
Maximum supply you should store
A rough rule for the Florida summer:
| Animals | Max bales to store at once |
|---|---|
| 1–2 horses | 30 days' supply |
| 3–10 horses | 45 days' supply |
| 10+ horses or commercial | 60 days' supply |
More than 60 days of hay stored through July–August carries real spoilage risk unless you have a climate-controlled barn. Standing orders solve this — instead of storing 90 days at a time, you take 30 days and we hold the rest in our barn.
Why standing orders beat big stockpiles in Florida
Storage costs are real even when they're hidden:
- Pallets and tarp: $80–$200 per stack
- Mold loss: 5–15% of any improperly stored Florida summer hay
- Labor to restack and inspect: 1 hr per 50 bales every 2 weeks
A monthly standing order eliminates all three. We store the bales in a climate-stable barn, you take a 30-day supply at a time, and the math works out cheaper than self-storing through humidity season.
Quick checklist
- ✓ Pallets under every bale (6" minimum off the ground)
- ✓ 12" airflow on all sides
- ✓ Top-covered only, not side-wrapped
- ✓ Inspect a sample bale every 2 weeks
- ✓ Limit summer storage to 30–60 days max
- ✓ Standing order for anything beyond 30 days
