Why does storage matter?
Most crops are harvested in a short window, and storage lets you spread out selling or eating. It also reduces waste. But poor storage can wipe out the crop you worked hard to grow.
Different crops need different conditions, so there is no single answer. Learn the needs of each crop you plan to store.
Before building or buying anything, decide how much you really want to store and for whom. A few bushels for the family call for different space than a market operation selling through the winter. Write down storage temperatures, dates in and out and losses for each crop, so that next year you can compare your results and make better choices about what to grow.
Which crops store well?
Some crops keep for months, such as certain winter squash, onions, potatoes, apples and root crops, while others spoil in days, such as berries and tender greens. Variety matters too, since some are bred to store and others are not.
Ask your extension office which crops and varieties store best in your area, and for how long.
Keep a short test list. Store a small sample of each variety and check it over the winter. What lasts in your hands is the best guide to what to grow more of next season.
- Onions, garlic and potatoes, if cured and kept well
- Winter squash and some apples
- Carrots, beets and cabbage in cool, humid space
Why is harvest condition important?
Only store healthy, undamaged crops. A bruise or cut can start rot that spreads. Harvest at the right maturity and handle gently, since rough handling shortens storage life.
Remove field heat quickly and keep produce out of the sun after harvest.
Wet weather before harvest can shorten storage life, and so can disease in the field. Healthy plants make healthy storage crops, so good field practices count here too.
- Store only sound produce
- Handle gently
- Cool quickly after harvest
What about curing?
Some crops, such as onions, garlic, potatoes and some squash, are cured before storage. Curing heals small wounds and dries outer skins. Conditions and times differ by crop, so follow extension guidance. Ask neighbors who store crops what they have learned about timing, since local weather changes curing conditions from year to year, and keep notes of your own results.
Do not skip curing, and do not rush it. Poorly cured crops often rot in storage.
Some growers use a warm, humid space for curing and then move crops to cooler storage. Others cure outdoors under cover in good weather. Ask your extension office which setup fits your crops and climate.
How do temperature, humidity and airflow work?
Each crop has its own best temperature and humidity range. Too warm and crops sprout or rot, too dry and they shrivel, too wet and mold grows. Air movement helps prevent hot spots and condensation.
Use thermometers and, if possible, a humidity gauge. Placing sensors at crop level gives better information than checking the air near the door.
Different crops want different conditions. Some like cold and very humid air, while others, such as onions and winter squash, prefer drier, warmer storage. Putting everything in one place means something will suffer.
- Check temperature at crop level
- Leave gaps between containers
- Keep humidity suited to each crop
Can you store different crops together?
Some crops give off gases that shorten the life of others, and some absorb odors. Apples, for example, can affect nearby produce. Keep incompatible crops apart.
Ask local experts which pairings to avoid.
Space matters as well. Crowded crates block air and trap heat, so leave gaps and avoid piling too deep. Stack containers so air can pass between them.
How do you check stored crops and prevent pests?
Inspect stored crops regularly and remove anything rotting at once, since one bad piece can ruin the rest. Keep storage clean, sealed against rodents and free from old crop debris.
If you sell stored produce, keep it clean and labeled, and check state rules for selling. Keep notes on what worked this year to plan better next year.
Rodents and insects find stored crops quickly. Close gaps, remove spilled produce and avoid leaving poison where children, pets or livestock can reach it, and ask your extension office about safe pest control.
- Look through stored crops weekly
- Remove soft or moldy items at once
- Record losses to plan next year
Key takeaways
- Store only healthy, undamaged crops.
- Cure crops that need it, and do not rush.
- Match temperature, humidity and airflow to each crop.
- Check often and remove spoiling produce.
