Use and Preserve the Harvest

Planning What to Do With Surplus Produce

Route surplus before quality declines.

A basket of extra tomatoes, beans, cucumbers, greens, squash, peppers, herbs, or fruit is not yet a preservation project. It is a decision problem. Some food should be eaten tonight. Some can wait. Some is better shared while fresh. Some is worth freezing or drying. Some can be safely canned or fermented only through a research-tested process. Some should never enter a human-food channel. This guide helps you decide before the harvest loses the quality that made it worth growing.

Capability promise. After using this guide, you should be able to inventory a surplus harvest; separate safety problems from ordinary cosmetic damage; rank produce by urgency; match produce to realistic household use, storage, sharing, donation, or preservation capacity; reject preservation methods that lack a safe tested procedure; create a batch plan; label and inventory preserved food; and use the record to improve next season's planting plan.

The five-minute answer

Screen the food first. Separate rotten, moldy, contaminated, or otherwise unsafe produce before planning storage or preservation. Preservation is not a rescue method for unsafe food.
Sort by urgency. Highly perishable crops and fully ripe produce usually need a decision sooner than sound storage crops. Crop-specific storage conditions matter.
Reserve what you will actually eat fresh. Write the meals, snacks, or household uses that can absorb the produce during the next several days.
Use simple storage when it is enough. Some crops can be held safely and with good quality under the right temperature and humidity. Do not process food simply because it exists.
Share or donate high-quality food while it is still useful. Use the garden's #55 distribution system for recipient fit, custody, records, and institutional requirements.
Preserve only through a method that fits both the food and your capacity. Freezing, drying, canning, and fermentation have different equipment, time, storage, power, recipe, and safety requirements.
Choose the tested procedure before starting the batch. Especially for shelf-stable canning and pickling/fermentation, do not invent a process after the produce is already cut.
Label, date, inventory, and use the result. A pantry or freezer full of forgotten food is delayed waste, not successful preservation.
Feed the lesson back into the garden plan. Repeated surplus may mean you should plant less, stagger planting, harvest differently, recruit a recipient earlier, or deliberately grow for preservation next year.

#64 Planning Surplus

The gardener or household decision system: what should happen to this particular surplus, in what order, using what real capacity?

#65 to #68 Preservation Guides

The specialist methods for freezing, dehydrating, canning, fermenting, and pickling. #64 routes the crop to the right method but does not replace those procedures.

First screen: is this food still suitable for a human-food plan?

FDA advises choosing produce that is not bruised or damaged, cutting away damaged or bruised areas before preparation, and throwing away produce that looks rotten. Washing can reduce surface bacteria but does not eliminate them. That means washing, cooking, freezing, drying, canning, or fermenting should not be used as a blanket excuse to keep food with an unresolved contamination problem.

Finding	Meaning	Action
Sound, mature produce with no known contamination concern.	Eligible for normal use, storage, sharing, or an appropriate preservation method.	Proceed to urgency and capacity triage.
Small bruise or minor damage that can be removed during ordinary preparation.	Quality defect may be manageable.	Modify by trimming and using promptly if the remainder is sound.
Rot, mold, slime, strong off odor, or widespread decay.	Poor candidate for storage or preservation.	Stop the human-food route. Follow appropriate disposal or garden-compost rules.
Known or suspected floodwater contact, chemical contamination, sewage exposure, unsafe agricultural water, animal fecal contamination, or another unresolved safety event.	This is not an ordinary surplus problem.	Stop and use the applicable food-safety, flood, water, or contamination procedure before deciding disposition.

Put the harvest on a quality clock

Different crops have very different storage requirements. University of Minnesota Extension notes that temperature and humidity are the main storage factors and that expected storage life is only an estimate. A household refrigerator is not automatically the right long-term environment for every crop. USDA's FoodKeeper likewise treats storage times as guidelines rather than hard rules.

Use first

Highly perishable or fully ripe

Leafy greens, tender herbs, berries, sweet corn, very ripe fruit, and similar crops often lose quality quickly. Confirm crop-specific handling, then route these first.

Plan next

Moderate holding window

Many beans, cucumbers, summer squash, peppers, and ripe tomatoes need a near-term plan but may give you enough time to cook, share, or schedule a preservation batch.

Verify storage

Storage-capable crops

Sound onions, garlic, winter squash, roots, potatoes, and similar crops may be better stored than immediately processed, but curing, temperature, humidity, ventilation, and variety matter. Use local Extension guidance.

Do not manufacture universal shelf-life numbers. Variety, maturity, field conditions, harvest damage, temperature, humidity, and household storage conditions can change how long produce keeps. Use FoodKeeper and crop-specific Extension guidance rather than a single national chart copied from mixed sources.

The surplus routing table

Route	Choose it when	Capacity you must have	Main boundary
Eat or cook now	The household can realistically use the food before quality declines.	Meal plan, preparation time, refrigerator space when needed.	Do not keep producing leftovers the household will not eat.
Short-term store or cure	The crop stores well and you can provide appropriate conditions.	Correct temperature, humidity, ventilation, sanitation, and monitoring.	Storage preserves quality only within the crop's limits. It does not improve poor produce.
Share or donate fresh	Produce is high quality and another person or recipient can use it promptly.	Recipient, timing, transport, packaging, and any garden/institutional requirements.	Use #55 for the actual distribution system.
Freeze	The food freezes well, you have freezer capacity, and the expected use justifies ongoing frozen storage.	Freezer space, reliable power, packaging, crop-specific preparation and blanching where required.	Freezing does not sterilize food and some foods freeze poorly.
Dehydrate	The food has a research-supported drying method and the household will use the dried form.	Controlled drying equipment/conditions, pretreatment when required, packaging, dry storage.	Drying must remove enough moisture and the finished product must stay dry. Not every outdoor drying method is appropriate.
Can or pickle for shelf storage	A current research-tested recipe exists for the exact product and you have the proper canner, jars, time, and altitude adjustment.	Validated recipe, correct equipment, sound produce, measured ingredients, process control.	Do not invent a shelf-stable canning process or alter safety-critical recipe proportions.
Ferment or refrigerated-pickle	A research-based method fits the crop and you can control the required proportions, time, temperature, and storage.	Appropriate recipe, vessels, ingredients, temperature control, monitoring, storage.	Do not improvise salt, acid, or food-to-liquid ratios where safety depends on them.
Compost or discard	The food is no longer appropriate for a human-food route or there is no realistic use before loss.	A permitted, appropriate waste or compost pathway.	Some contaminated material should not enter a community compost system. Follow #52 and any incident-specific guidance.

Choose by capacity, not enthusiasm

Preservation can move work from one day to another, but it cannot remove work. Every method consumes some combination of time, equipment, storage space, electricity or fuel, clean work space, containers, ingredients, and attention. Before committing a basket to preservation, audit the actual bottleneck.

Question	If yes	If no
Do we already know how this food will be eaten later?	Preservation has a defined purpose.	Prefer fresh use, sharing, or a small test batch instead of preserving by reflex.
Do we have a current authoritative procedure for this exact method/product?	Continue to equipment/capacity check.	Do not begin a safety-critical process while searching for a recipe mid-batch.
Can we complete the batch while the produce is still high quality?	Schedule it.	Use a faster route such as eating, sharing, freezing when appropriate, or reducing batch size.
Do we have enough destination storage?	Reserve and label space before starting.	Do not create more jars, packages, or dried food than can be stored appropriately.
Will the household use last year's preserved stock before making another large batch?	Use FIFO and plan quantity.	Reduce the new batch and revise planting quantity.

Preservation method boundaries you should know before #65 to #68

Freezing

NCHFP describes freezing as a convenient preservation method but emphasizes that freezing does not sterilize food. Most vegetables require crop-specific blanching for quality, and some foods have poor texture after thawing. Use #65 for the actual method.

Dehydrating

Drying reduces water activity enough to extend storage when performed correctly. Finished foods must be dry enough, cooled, packaged to resist moisture, and monitored for moisture pickup. Outdoor sun drying is not appropriate for all foods. Use #66 for the method.

Canning

Shelf-stable home canning depends on a tested process. Penn State's July 2026 guidance stresses that heat penetration depends on acidity, consistency, piece size, solid-to-liquid ratio, jar size, starting temperature, and other variables. There is no safe general formula for inventing processing times. Use #67.

Fermenting and pickling

Acid, salt, food, water, temperature, and time can be safety-critical. NCHFP advises using tested proportions for pickled and fermented products. Use #68 rather than improvising from a social-media recipe.

Build the batch plan before touching the knife

Write the crop and amount. Use a kitchen scale or a consistent household measure when possible.
Record harvest date and condition. Note whether produce is fully ripe, needs curing, is heat-stressed, bruised, or otherwise time-sensitive.
Allocate fresh use first. Name the meals or recipes, not just “eat some.”
Allocate storage-capable produce. Record the storage location and required conditions.
Allocate sharing/donation. Confirm recipient and delivery timing before setting food aside.
Choose preservation methods. Link each batch to a current authoritative procedure before preparation begins.
Check equipment and destination capacity. Freezer space, dehydrator trays, correct canner, jars, lids, storage containers, labels, and shelf space should exist before the batch grows.
Assign a deadline. “Tomorrow” is a plan. “Sometime this week” is often how surplus becomes waste.
Label and inventory the result. Record product, date, quantity, and any recipe/source identifier needed to know how it was made.

Common surplus-planning failures

Symptom	Likely cause	Immediate response	Prevention
A counter fills with produce faster than it is processed.	Harvest volume exceeded available time.	Stop adding batches; eat/share the most perishable sound produce first.	Harvest in smaller waves and pre-schedule preservation days.
Freezer fills with unlabeled bags nobody recognizes.	Preservation happened without an inventory/use plan.	Inventory and label what can still be identified safely; build meals around older stock.	Label/date at packaging and reserve freezer capacity before harvest.
Many jars are made because “canning season” arrived.	Tradition replaced demand planning.	Stop new batches until existing inventory and likely use are reviewed.	Preserve to a one-year use plan, not to empty-jar capacity.
Recipient declines donated produce.	Recipient fit was checked after harvest.	Redirect promptly through #55 while quality remains high.	Confirm accepted crops, quantities, timing, and packaging before harvest.
Gardeners repeatedly have the same unwanted surplus.	Planting quantity, succession, or household preferences are mismatched.	Record the pattern.	Plant less, stagger plantings, or grow intentionally for a proven preservation/donation route.
Someone wants to can a family salsa or mixed vegetable recipe with no tested process.	The recipe is being treated as a canning process.	Do not shelf-can it. Use a validated recipe or another safe storage method such as refrigeration/freezing as appropriate.	Select the tested recipe before planting or batch preparation.

Stop conditions

Do not preserve rotten or moldy produce to “save” it. FDA advises throwing away produce that looks rotten. NCHFP canning guidance starts with good-quality fresh food and rejects diseased/moldy food.

Do not invent a shelf-stable canning process. If a current USDA, NCHFP, or Extension-tested recipe/process does not match the product, choose another route or wait for #67 guidance.

Do not assume freezing or drying sterilizes food. These methods control growth and quality in different ways but do not erase a prior contamination problem.

Do not treat flood-contact produce as ordinary surplus. Use #58's crop-disposition rules first.

Do not donate questionable produce simply to avoid waste. A recipient should receive food you would be willing to serve under the same safety standard.

Do not preserve beyond your safe working capacity. If the process requires attention you cannot provide, reduce the batch or choose a simpler route.

Verify this locally

Crop storage and harvest conditions: your Cooperative Extension office or land-grant university.
Canning altitude adjustments and current recipes: USDA/NCHFP or your Extension food-preservation program.
Donation rules and recipient specifications: the actual pantry, food bank, school, nonprofit, or institutional recipient and applicable health/agriculture authorities.
Community compost acceptance: the garden's #52 compost-system rules and local organics requirements.
Produce exposed to a contamination event: use the applicable health, agriculture, environmental, or Extension guidance before choosing a food route.

Do this yourself: triage one real harvest

Take the next basket that is larger than your household can immediately use and do not put it on the counter as one undifferentiated pile.

Weigh or count it.
Remove anything unsuitable for human food.
Rank the remainder by urgency.
Assign a fresh-use quantity to named meals.
Assign a short-term storage quantity only if you know the storage conditions.
Assign sharing/donation only after confirming a recipient.
Assign preservation only after locating the procedure and confirming equipment/storage capacity.
Give every quantity a deadline.
At the end of the week, record what was actually eaten, preserved, shared, or lost.
