Harvest, Storage & Post-Harvest TimingHarvest Timing for Tree Fruit
Tree fruit has a window rather than a date. Pick too early and fruit is starchy and sour, and pick too late and it softens, drops or rots.
Key points
- Track bloom date and harvest date for each variety.
- Use ground color, firmness, seed color, ease of release and taste together.
- Pick in several passes, since fruit on one tree ripens unevenly.
- Check pesticide pre-harvest intervals and local rules before every spray.
What decides the harvest date for tree fruit?
The clock starts at bloom. Each variety needs a certain number of weeks from bloom to maturity, and warm springs and summers speed that along. Because of that, the same variety can ripen in different weeks in different years.
Keep a record of bloom date and first harvest date for each variety. After a few seasons you will see the pattern, and you can predict the next harvest with a margin for weather.
Do not rely on a single sign. Pick a few fruit, cut them open, taste them, and compare them with what you saw outside, then decide.
Which signs show fruit is ready?
Growers use several signs together. Ground color, the background color under the red blush on apples, changes from green toward yellow as fruit matures. Flesh firmness drops, seeds darken from white to brown in apples and pears, and the fruit separates from the spur more easily with a lift and twist. Taste is the final test.
Stone fruit such as peaches and cherries are judged by background color and taste. Cherries do not sweeten after picking, so wait until they are fully colored and test a few. Peaches are picked firm ripe and soften after harvest, but fruit picked too green stays hard and sour.
What about apples and pears specifically?
Apple growers often use a starch test, where a cut fruit is dipped in iodine solution to show how much starch has turned to sugar. The pattern of color tells how far along the fruit is. Extension fruit specialists publish charts for the test, and procedures vary by variety, so ask your state extension program for the version they use.
Pears differ from apples because many types are picked mature but still hard, then ripened off the tree. Pears left to ripen on the tree often turn gritty or mealy inside. Learn the rule for your variety from your extension office.
How do you handle a long harvest from one tree?
Fruit on a single tree does not ripen all at once. Sun exposed fruit on the outside and top ripens first, so many growers pick in two or three passes over a week or more. Use clean, shallow containers and handle gently, since bruises show up as brown spots later.
If fruit drops in quantity before it seems ripe, check for pests and stress. Heavy drop can also come from overcropping, which thinning earlier in the season helps prevent. Ask your extension office for thinning guidance.
How do frost and weather affect the year?
A frost at bloom or just after petal fall can remove much of the crop. Check your trees' bloom time against the average last spring frost for your area. Low spots hold cold air, and growers sometimes find a better site or choose later blooming varieties.
Heat can speed ripening and soften fruit on the tree. Heavy rain near harvest can cause splitting in cherries and other fruit. If rain is coming and fruit is ready, an early pick may be worth considering.
What are the pest and spray points to know?
Insects and diseases can affect fruit right up to harvest. If you use any pesticide, the label is the law, and pre-harvest intervals apply, so check the interval against your picking plan. Applicator licensing varies by state, and pollinators visit trees at bloom, so protect them. Your extension office publishes current spray guides for tree fruit in your region.
Thinning and pruning for good light and airflow also help fruit finish evenly and make pest and disease control easier, so ask extension about the schedule for your tree type.
How should fruit be stored or preserved?
Cool fruit promptly after picking. University of Wisconsin Extension notes that chilling can injure some crops, and apples can show internal browning in the wrong conditions. Follow your extension office's guidance on storage conditions for your variety.
For canning, drying, freezing or making cider, use tested procedures from the National Center for Home Food Preservation or extension. We do not give times, temperatures or pressures here.
