Summer Harvest Management

How do I know when to harvest each crop?

Each crop has its own signs of readiness: color, size, firmness, aroma or ease of release from the plant. Seed packets and extension guides describe these for each variety, and learning them prevents both underripe and overripe picking.

Check plants often during the peak of the season. Some crops, such as summer squash and beans, grow quickly and can pass their best in a day or two. Frequent picking also encourages many plants to keep producing.

If you are unsure whether something is ripe, ask your extension office or an experienced neighbor, and never eat or sell anything you cannot confidently identify as a crop you planted.

• Learn the readiness signs for each crop
• Harvest on a regular schedule
• Pick often to keep plants producing
• Keep notes on what ripened when

What is the best time of day to pick?

Early morning is usually best because plants are cool and full of moisture. Produce picked in the heat of the afternoon wilts faster and has a shorter shelf life.

Bring shade with you. A shaded cart or a cooler near the garden keeps freshly picked crops from heating in the sun. Move harvested food quickly to a cool place.

Wet produce stores poorly, so avoid picking right after rain or heavy dew unless the crop is going straight to use. Dry hands and dry containers reduce rot.

How should I handle and cool produce?

Handle produce gently, because bruises and cuts shorten storage life and invite spoilage. Cool crops quickly after harvest. Different crops prefer different storage conditions, and some, such as tomatoes and basil, dislike cold. Extension publications describe the right conditions for each.

Do not wash crops until you are ready to use them unless they need immediate cooling, and use clean containers. Wash hands before harvesting and keep animals and their waste away from harvest areas and containers.

Sort as you pick. Setting aside bruised or split produce for immediate use keeps one bad piece from spoiling the whole crate.

• Use clean, food-safe containers
• Keep produce out of the sun
• Store cold-sensitive crops properly
• Separate damaged produce from good produce

What food safety basics apply to harvesting?

Food safety starts in the garden. Keep manure and raw compost away from crops, wash hands and tools, and use water suitable for the job. Avoid harvesting produce that has been in contact with animal waste or flood water.

Foodborne illness is a real risk. If you sell produce, rules for licenses, labeling and food safety vary by state, county and town. Ask your state department of agriculture and county health office what applies before you sell.

Wash harvest bins and knives between uses, and keep pets and poultry out of the garden at picking time.

What do I do with a sudden glut?

Plan for surplus before it arrives. Share with neighbors, donate to a local food pantry that accepts garden produce, trade with other growers or sell through a lawful outlet. Check with the pantry first about what they accept.

If you plan to preserve extra produce, use only current tested methods from the National Center for Home Food Preservation, the USDA Complete Guide to Home Canning or your extension office. Do not use old family recipes or untested methods, since the risks include serious foodborne illness.

Check with your county health office and state agriculture department on any rules for donating or selling, since requirements differ by place.

How do I keep records of the harvest?

Simple records pay off. Log what you picked, when and how much, plus any losses and the reasons for them. Over a few seasons you will see which crops deserve more space and which are not worth the effort.

Use the records to plan succession planting, spacing and seed orders for next year. They also help you judge how much to grow for your family and how much surplus to expect.

A written plan for how much family and neighbors can actually eat keeps you from overplanting in spring and drowning in surplus by August.

• Record dates and amounts for major crops
• Note weather, pests and disease
• Track what went to waste and why
• Review the log before ordering seed

How do I protect plants and soil after the main harvest?

When a crop finishes, remove spent plants promptly, especially diseased ones, and do not compost them unless your compost is managed properly. Replant with a quick fall crop or sow a cover crop to protect the soil.

Bare soil in summer heat loses moisture and structure. Mulch or cover bare beds quickly and note what grew there so you can rotate crops next season.

Compost spent plants only if they are healthy, and keep diseased material out of the pile.
