One day, after years of planting, watering, pruning and waiting, a tree hands you more fruit than your family can eat. That's the moment this whole course has been building toward, and it raises a happy problem: what to do with it all.
This lesson covers picking at the right moment, storing fruit and nuts fresh for months, preserving the rest safely, and sharing the surplus generously. It's where the orchard finally feeds the family all year round.
- 1Tell when each fruit and nut is ready to pick.
- 2Store fresh fruit and nuts so they last.
- 3Choose the right way to preserve each harvest.
- 4Can fruit safely, including altitude adjustments.
- 5Plan your harvest, and share the surplus.
Picking at the right moment
| Harvest | It's ready when… | Tip |
|---|---|---|
| Apples | The fruit lifts and twists off easily, the seeds are brown, and it tastes right | Pick a test apple and taste it before harvesting the whole tree |
| Pears | Full size and the color just starts to lighten, but still hard | Most European pears ripen best off the tree: chill them, then ripen at room temperature |
| Peaches and plums | The background color turns from green to yellow, and the fruit gives slightly | They ripen on the tree; pick every day or two at peak |
| Cherries | Full color and sweet | Pick with the stems on so they keep longer; net against birds |
| Figs | Soft, drooping on the stem, sometimes with a drop of nectar at the eye | They don't ripen after picking |
| Chestnuts and walnuts | Nuts fall from opened burrs or split hulls | Gather every day or two before animals do; wear thick gloves for chestnut burrs and walnut hulls, which stain |
Handle fruit gently. A bruise today is a rotten spot next month, and one bad apple really can spoil the box.
Storing the fresh harvest
- Store only perfect fruit; use bruised ones right away
- Keep them as close to freezing as possible, about 30–32°F, with high humidity
- A cold garage, cellar or spare refrigerator works
- Late-season apple varieties keep for months
- Keep apples away from vegetables: the gas they give off makes greens and carrots spoil and turn bitter
- Chestnuts are moist and perishable: refrigerate them and use within weeks, or dry or freeze them
- Walnuts and hazelnuts: remove hulls, dry in a single layer for a few weeks, then store cool in mesh bags
- Shelled nuts keep longest in the freezer
- Toss any nuts that smell rancid or show mold
A simple root cellar, cold room or insulated pantry on the north side of the house (Natural Building Lesson 2) can keep apples crisp into spring. Few things feel richer than a cellar shelf of fruit in February.
Preserving
Canning safely
Canning is the most rewarding method, and the one where mistakes matter most. The bacteria that cause botulism can survive improper canning, so follow these rules every time.
- Use tested recipes only. Follow the USDA guide or the National Center for Home Food Preservation, not old family recipes or internet improvisations.
- Know your acid. Fruits like apples, peaches, pears, plums and cherries are acidic enough for a boiling water canner. Low-acid foods (most vegetables, nuts, meats) need a pressure canner.
- Acidify tomatoes. Add 1 tablespoon of bottled lemon juice per pint (2 per quart), or ¼ teaspoon of citric acid per pint (½ per quart).
- Adjust for altitude. Water boils cooler up high, so add processing time in a water bath canner.
- Check every seal. Lids should be pulled down and not flex. Refrigerate and use any jar that didn't seal. Never eat from a jar that's bulging, leaking, spurting or smells off.
| Your altitude | Add to boiling water canning time |
|---|---|
| 0–1,000 ft | Use the recipe time |
| 1,001–3,000 ft | +5 minutes |
| 3,001–6,000 ft | +10 minutes (Mount Shasta is about 3,600 ft) |
| 6,001–8,000 ft | +15 minutes |
| 8,001–10,000 ft | +20 minutes |
The easier methods
Tray, then bag
Slice fruit, spread it on a tray to freeze, then bag it so pieces don't clump. A little lemon juice keeps apples and peaches from browning.
Low and slow
Thin slices in a dehydrator around 135°F until leathery, or in the sun in hot, dry climates. Fruit leather uses up soft fruit.
Vinegar from scraps
Apple peels and cores in sugar water become apple scrap vinegar in a few weeks. For canning, use commercial vinegar of known strength.
Plan your harvest
Before you plant more trees, picture the harvests they'll bring. It helps you plant what your family will actually eat and preserve.
How much fruit will your trees give?
| Tree | Size | How many | Lb a year |
|---|---|---|---|
| Apple | |||
| Pear | |||
| Peach | |||
| Plum | |||
| Sweet cherry |
Uses the middle of nursery yield estimates for mature trees in a good year (apples 42 lb a bushel, pears and peaches about 48–50, plums 56, cherries about 1.5 lb a quart). Real harvests swing widely with weather, care and age. About 3 lb of fruit makes a quart of sauce or canned fruit; fruit dries to roughly a sixth of its fresh weight.
Share the surplus
Remember the third permaculture ethic from the start of the Plan courses: share the surplus. A mature orchard almost always grows more than one family can use. That extra can do a great deal of good.
- A basket on the neighbor's porch
- Trades with other growers: your apples for their honey or eggs
- A local food bank or community meal
- Gleaning groups that pick for people in need
- A cider or canning day where everyone brings jars and leaves with some
Many families mark the first harvest of each tree, or hold a fall harvest day with neighbors: picking together, pressing cider, sharing a meal. Traditions like these turn a busy season into the best memory of the year, and invite others into the work and the joy.
Preserve a harvest three ways
Take one harvest, your own or from a farm stand or U-pick orchard, and preserve it three ways: dried, frozen and canned. Then hold a taste test and start the family pantry record.
You'll need
- About 20 lb of apples, pears or peaches
- A dehydrator or oven, freezer bags and a baking tray
- A boiling water canner, jars, new lids and a jar lifter
- A tested recipe from the National Center for Home Food Preservation
- Labels and a marker
- Your altitude
Do it together
- Sort the fruit: perfect fruit to store fresh, good fruit to preserve, bruised fruit for sauce or vinegar.
- Dry a batch: thin slices on dehydrator trays until leathery.
- Freeze a batch: slice, tray-freeze, then bag and label.
- Can a batch of applesauce or fruit with an adult, following the tested recipe and adding time for your altitude.
- Check the seals the next day and label every jar with the date and contents.
- Hold a taste test a few weeks later, and start a pantry list of what you have and what you'd make more of.
Little preservers
- Wash and sort the fruit
- Lay slices on the drying trays
- Draw and stick on the labels
Older preservers
- Read the tested recipe aloud and track each step
- Calculate the altitude adjustment and processing time
- Weigh fruit before and after drying and calculate the weight lost
Hot jars, boiling water and sharp knives are adult jobs; children can wash, sort, label and help with cool tasks. Photograph your shelf of preserves for your progress record.
The harvest that keeps on giving
A jar of peaches opened in January holds a summer afternoon inside it. A bag of walnuts from a tree your children planted is a small miracle. That's the reward of thinking in decades: a family fed, a pantry full, neighbors blessed, and trees still growing for the next generation.

- 2The layers of a food forest.
- 3Choosing trees for your climate.
- 4Planting guilds that support each other.

- 6Harvest, storage and preserving.
Next, we turn from the land itself to the people who grow up on it: raising children with rhythm, responsibility and wonder.
