Harvest, Storage & Post-Harvest TimingDehydrating Calendar
Drying works well for crops that come in more than you can eat fresh. A calendar helps you line up drying days with harvest and make use of your equipment.
Key points
- Use tested drying methods for each food.
- Dry at peak quality and plan drying days around harvest.
- Condition and store in airtight containers, and check often at first.
- Keep records to improve next year's plan.
- Use pretreatment and doneness tests from a tested guide for each food.
Why plan dehydrating ahead?
Drying takes time and space, and the crops often arrive together. Without a plan you may find a pile of produce and a dehydrator already full. A calendar spreads the work and helps you pick the best crops for drying.
Tested drying instructions, including preparation, pretreatment and doneness tests, are available from the National Center for Home Food Preservation and your extension office. Follow them for each food rather than guessing.
Think of drying as the third or fourth choice for a crop after eating fresh, freezing and perhaps canning. It earns its place for herbs, fruit leathers, apple rings, peppers and tomatoes you want to keep compact.
Which crops dry well?
Many herbs, apples, pears, peppers, tomatoes, berries and some root vegetables are good candidates. Others, such as high-fat or very watery foods, may need special handling or are better preserved another way. Check a tested guide for your crop.
Dry produce at its best quality. Drying concentrates flavor, but it does not fix problems with overripe or damaged fruit.
Ask your extension office whether your crop needs a pretreatment, such as blanching or a dip, before drying. Tested guides list these steps by food, and skipping them can change color, flavor and storage life. Slice pieces to an even thickness so a tray finishes together, since thick and thin pieces dry at different rates.
What does a drying calendar look like?
Start with the crops you grow or buy and when they are ready. Mark drying days that match, remembering that herbs are often best dried before flowering and that fruit and vegetables should be at peak ripeness. Then add a conditioning step and a check after storage.
For example, if your herbs reach good size before your first summer heat peak, schedule early morning harvest and drying right away, using your extension office's advice on timing and handling. Herbs dry best when cut after the dew has dried and before the day gets hot, then spread in a thin layer with good airflow.
- List crops and expected harvest times
- Match each to a tested drying method
- Plan prep, loading and checking
- Schedule conditioning and storage checks
How do you choose equipment and a place?
Electric dehydrators, ovens and sun or solar drying each have their place. The right choice depends on your climate, since humid weather makes outdoor drying difficult. Tested guidance describes what each method needs.
Clean equipment and trays before use, and set up where you have good airflow and a stable temperature. Keep drying food away from dust, insects and pets.
Humidity is the main limit on outdoor drying, so if your area gets humid summers you may do most drying indoors. Never dry food near a source of fumes, and keep it covered from insects.
How do you know when food is dry enough?
Each food has its own doneness description in tested sources. Dry food that is too moist can mold in storage, and food that is overdried loses quality. Let pieces cool before testing them, since warm pieces feel softer than they are.
Many guides recommend a conditioning period, in which dried food sits loosely in a container for a short time so moisture evens out. Follow the instructions for your food.
A worked example: if a tray of apple slices still feels sticky when cooled, it is not ready. Give it more time and test again, using the doneness description in your tested guide.
How should dried food be stored?
Use clean, dry, airtight containers, kept in a cool, dark place. Label with contents and date. Check containers in the first weeks for signs of moisture, and if you see any, re-dry or discard according to tested guidance.
Use older food first, and check for pests. Dried foods can attract moths and beetles if containers do not seal well.
Freezing dried food for a short period is sometimes recommended to deal with insect eggs. Ask your extension office or NCHFP whether that applies to your food.
What records help?
Note what you dried, how long it took, the weather and how the food held up. These notes help you choose crops and plan trays next year.
Check NCHFP before each season for updated guidance. Over a few seasons these notes will tell you which foods you actually eat dried.
