Section 1 Overview
Blanket storage might seem straightforward—you take them off in spring, fold them up, and put them away until next winter—but improper storage causes significant damage to expensive blankets. Blankets stored damp develop mold and mildew that weakens the fabric and creates an unpleasant smell that's difficult to eliminate. Blankets stored in damp or humid environments succumb to the same fungal problems. Blankets stored where rodents can access them get chewed, creating holes that compromise insulation and waterproofing. Even blankets stored in theoretically ideal conditions can deteriorate if stored incorrectly, with creases becoming permanent and straps tangling into useless knots.
The good news is that proper storage isn't complicated, and the investment of time and attention in spring pays off tremendously when you pull blankets out in fall and they're in good condition, ready to use immediately. The key principles are keeping blankets clean and dry before storage, storing them in a location that's protected from moisture and pests, and organizing them in a way that prevents damage during the storage period.
Many people underestimate how important blanket condition is to their usefulness. A blanket with compromised waterproofing doesn't keep your horse dry effectively. A blanket with broken straps becomes unsafe to use. A blanket with significant holes stops providing insulation where it's needed. These problems develop much faster in blankets that are stored improperly and then used hard through the winter.
The amount of time you spend storing blankets properly in spring is genuinely one of the best investments you can make in your blanket's longevity. I've had blankets last me ten years or more with proper care, while friends with similar blankets that were stored poorly had to replace theirs every three to four years. The difference comes down to storage and basic maintenance, not the quality of the original blanket.
Understanding why each step of proper storage matters helps you take it seriously rather than rushing through the process. When you know that mold develops within days in damp conditions, you'll spend the time necessary to ensure blankets are fully dry. When you know that rodent damage is permanent and irreversible, you'll be more careful about where you store them. Taking the storage process seriously extends your blankets' useful lifespan and keeps them functional and effective through their entire life with you.
Section 2 Why It Matters
The fundamental reason proper storage matters is that blankets are expensive. A quality horse blanket costs several hundred dollars, and owning multiple blankets for different weather conditions means significant investment. Protecting that investment makes financial sense. Blankets that are destroyed by mold or rodents during off-season storage represent money wasted and force you to buy replacements before you planned to. Blankets properly maintained often outlast expectations and reduce your long-term blanket expenses considerably.
Blanket functionality depends on their being stored in condition. Waterproofing degrades if blankets are stored damp or in conditions that encourage fungal growth. The insulation fails if the blanket is damaged or if moisture compromises the internal padding. You can't see these problems when you first put the blanket on in fall—they manifest once the horse is wearing it and you discover that sections are wet through, or that damaged areas have compromised the blanket's effectiveness. Discovering problems once the blanket is in use means your horse is uncomfortable or cold while you deal with the problem.
Stored properly, blankets are ready to use immediately when the season changes. You can pull them out, do a quick inspection, and put them on your horse. Improperly stored blankets require cleaning, drying, mold treatment, or repair before they're usable. This puts you in a situation where your horse might need a blanket before you can get the blankets ready, forcing you to use inadequate blankets or make other uncomfortable compromises.
Mold and mildew cause health problems beyond just blanket damage. Spores from moldy blankets can irritate your horse's respiratory system or skin, and fungal problems in your tack collection spread to other items stored nearby. One badly stored blanket can contaminate an entire storage area. Keeping blankets clean and dry prevents these problems from developing and protects your horse's health.
Proper storage also protects other items stored nearby. Blankets stored correctly take up less space and don't leak moisture onto saddles, bridles, or other equipment. This means your entire tack collection stays in better condition. When everything is organized and protected, your whole barn storage situation becomes more functional and manageable. This matters more than it might seem when you're dealing with limited storage space and trying to keep everything in good condition.
Section 3 How To Do It
Before storing blankets, they must be completely clean and dry. If the blanket is visibly dirty from winter use, rinse it thoroughly with a hose to remove mud and hay. Let it dry completely in the sun if possible—sunlight is natural antimold protection and helps dry blankets more thoroughly than air drying in shade. This might take a full day or more depending on the blanket's thickness and the weather. Don't rush this step; damp blankets stored for months is how mold develops.
Once blankets are dry, inspect them carefully before storing. Look for any damage—torn seams, broken straps, ripped material, or separation of the outer shell from the lining. Minor repairs are much faster to do now than in fall when you need the blanket ready quickly. Fix broken straps, sew small seams that are separating, and repair any holes or tears if they're large enough to matter. This takes time but prevents problems later and ensures the blanket is in good repair when you need it.
Fold blankets carefully to avoid creating permanent creases that become weak points. Rather than folding into tight bundles, fold blankets in thirds or quarters and store them where they can lay relatively flat. Some people use blanket storage bags designed to hold blankets without crushing them, which prevents creases and keeps everything compact. If you don't have proper storage bags, an old sheet or piece of fabric works as protection against dust while allowing air circulation.
Organize blankets by weight and type so you can find what you need quickly in fall. Store heavy blankets together, mediums together, and lighter weights separately. Label storage containers or bags with the blanket's weight and size—it sounds excessive until you're standing in your storage area in October trying to remember which bag contains which blanket. A simple label saves time and prevents you from pulling out the wrong blanket repeatedly.
Choose a storage location carefully. Ideally, store blankets in a place that's dry, cool, and protected from rodents. A tack room with concrete floors is often better than a wooden barn where rodents more easily gain access. An interior closet is better than an outdoor shed. If you must store in a location that's somewhat exposed, place blankets in airtight bins or sealed bags that rodents can't chew through. Cedar shavings or moth balls placed near storage can deter rodents, though the smell might be unpleasant when you first open stored items in fall.
Air circulation around stored blankets prevents moisture accumulation even in storage. Don't stack blankets tightly in a corner where air can't reach them. Leave some space, especially if your storage location isn't perfectly dry. In humid climates, a small fan running occasionally in the storage area helps prevent moisture buildup. Some people use silica gel packets in sealed storage containers to absorb excess moisture.
Check stored blankets occasionally throughout the off-season. A quick glance every month or so catches any developing problems before they become serious. If you notice any smell suggesting mold development, remove the affected blanket, dry it thoroughly, and treat any mold before returning it to storage. Early intervention prevents small problems from becoming storage disasters.
Section 4 Tools And Supplies
Blanket storage bags designed specifically for horse blankets are the ideal tool for storage. These bags are typically lightweight but durable enough to protect the blanket from dust and minor damage while allowing some air circulation. You can find them at tack shops or online, and they're surprisingly affordable considering the protection they provide. They usually hold one or two blankets depending on the design, and they compress enough to store efficiently in limited space.
If you don't have dedicated storage bags, old sheets, old blankets, or large pillowcases can serve as temporary protection against dust. The goal is keeping blankets protected while allowing some air movement—plastic bags that trap moisture are worse than no covering at all. Breathable fabric coverings solve the problem of dust while preventing moisture issues.
Storage bins or shelving help organize blankets and keep them off the ground, which is important for protection against ground moisture and rodents. Plastic storage bins with lids work well if you leave them partially ventilated to prevent moisture buildup inside the bin. Open shelving works too, as long as the shelves are in a protected location and you're using cloth covers for dust protection.
Labeling supplies—permanent markers, labels, or tags—help you identify stored blankets without opening every bag. This seems trivial but makes fall preparation much faster. You can label storage bags or create an inventory list posted near your storage area.
If you store in a location with rodent risk, cedar chips, mothballs, or rodent deterrent devices provide extra protection. Place these items near storage rather than directly in contact with blankets, as the smell can transfer to blankets. Traps are more effective than deterrents for serious rodent problems.
In humid climates, a small dehumidifier or silica gel packets help maintain dry conditions in your storage area. This is an investment worth making if you're storing expensive blankets long-term. Some people use moisture-absorbing products specifically designed for storage, which work similarly to silica gel.
Section 5 Frequency And Timing
Blanket storage happens once per year, typically in spring as temperatures warm and you stop using winter blankets regularly. The exact timing depends on your climate and your horse's needs, but as soon as you transition to using blankets only occasionally or have stopped using them for several weeks, it's time to store them. Waiting until mid-summer is fine if it extends your outdoor drying time, but don't delay so long that summer heat has already arrived, which makes blanket drying more difficult.
Prepare blankets for storage immediately after the blanketing season ends rather than setting them aside for later. That means cleaning and drying them within a few days of your last use. The longer you delay, the more likely blankets are to still be damp when you finally attempt to dry them, which increases mold risk. Getting storage done in early spring ensures you have clean, dry blankets ready to put away before warm weather makes drying difficult.
Once blankets are in storage, periodic checks throughout summer and fall help catch problems early. A quick monthly check—opening the storage area and looking for any signs of moisture, smell, or pest activity—takes five minutes and can prevent serious damage. More frequent checks aren't necessary unless you're in a very damp climate or you've had previous storage problems.
In late fall, begin preparing for blanket use again with enough time to repair or address any issues you discover. If you pull out your blankets in October and discover that one has developed mold or gotten damaged during storage, you want time to clean, dry, or repair it before you desperately need that blanket. Starting the new season with a full inventory check ensures you know what you have ready and what needs attention.
The cycle is essentially clean and dry in spring, check occasionally throughout summer and fall, and inspect thoroughly in late fall when you're preparing for winter use again. This routine keeps your blankets in good condition and prevents the major problems that develop from neglected storage.
Section 6 Tips And Troubleshooting
If blankets smell moldy when you pull them out in fall, you have options depending on the severity. A musty smell that comes out with airing usually indicates surface-level moisture rather than serious mold. Hang the blanket in the sun for a day or two and the smell typically disappears. If the smell is strong and doesn't improve with airing, or if you see visible mold, you'll need more aggressive treatment. Commercial mold-killing laundry additives designed for outdoor gear work well for horse blankets. Some people take heavily molded blankets to professional cleaners with commercial equipment that can handle them.
If you discover rodent damage, the blanket is unfortunately damaged permanently unless it's a small hole that you can patch. Rodent holes are usually scattered and irregular, and even small holes compromise the waterproofing and insulation of the blanket. Decide whether patching and using the damaged blanket is worthwhile or whether the damage is severe enough that replacement makes more sense. Sometimes a blanket with minor damage can be relegated to a backup or emergency blanket rather than being thrown away.
If you live in an extremely humid climate where mold is a constant threat, consider more aggressive prevention. Dehumidifiers, moisture-absorbing products, and more frequent inspection help, but you might also consider storing blankets in a climate-controlled space (like a house closet or heated barn) rather than an uncontrolled shed. The extra effort is worth protecting expensive blankets from mold damage.
Organization prevents problems that develop from poor storage habits. If you take time to organize blankets by weight and type, and to label everything clearly, you'll be more likely to store them properly and check on them occasionally. A disorganized pile of blankets in a corner gets forgotten, which is when problems develop. Taking five minutes to organize properly saves hours of trouble later.
Remember that a small amount of moisture or slight mustiness is normal in stored blankets in humid climates—the goal is preventing serious mold or damage, not achieving perfect conditions. Don't obsess over every tiny detail, but do pay attention to obvious problems like dampness, strong smells, or signs of rodent activity. Regular basic maintenance prevents almost all storage problems from developing in the first place.
