Harvest, Storage & Post-Harvest TimingHarvest Timing for Fruit Vegetables
Tomatoes, peppers, eggplant, cucumbers and squash are all botanical fruit, but they are harvested at very different stages. Knowing which stage each one wants is the whole job.
Key points
- Sort crops into ripe-pick and young-pick groups and treat them differently.
- Pick summer squash and cucumbers every few days to keep plants producing.
- Use steady moisture and mulch to limit cracking and blossom problems.
- Avoid chilling tomatoes and other cold sensitive crops.
Which fruit vegetables are picked ripe and which are picked young?
Tomatoes and hot peppers are usually left to color fully. Sweet peppers are often picked green, though they can be left on the plant to color, which takes longer and slows new fruit set. Cucumbers, summer squash and eggplant are picked before the seeds harden.
Iowa State University Extension recommends picking fully ripe tomatoes for best flavor, picking summer squash while the skin is still soft, and picking cucumbers at the size that suits their use. Each stage rule is a clue to how often you will need to be in the garden.
Sort your own crops into two lists, ripe and young, and put the second list on a short daily check.
How often should you pick?
Young-fruit crops respond to frequent picking. Iowa State suggests every two to three days for summer squash and cucumbers. Fruit left to grow large slows the plant down, since it signals that seed production is under way, and oversized fruit is often seedy, tough or bitter.
Tomatoes and peppers can be picked less often, but overripe fruit attracts pests and rots on the plant. Walk through at least every few days when production peaks.
How do you judge ripeness without guessing?
For tomatoes, look at full color for your variety and feel for slight give. Colors vary, since some varieties stay green or yellow when ripe, so learn what your variety should look like. For peppers, check size and firmness, and wait for full color if you want the ripe flavor.
Eggplant is ready while the skin is glossy and the fruit gives slightly under thumb pressure. A dull skin and brown seeds inside suggest it is overripe. Use your seed packet and extension notes for your specific varieties.
- Tomatoes: full variety color, slight give
- Peppers: firm, full size, color if you want ripe fruit
- Eggplant: glossy skin, flesh that springs back
- Cucumbers and squash: tender skin, target size
What does weather do to the harvest?
Heat can make fruit set poorly. Many growers see blossom drop in tomatoes and peppers during hot spells, and the harvest then comes in waves. Uneven watering can cause cracking in tomatoes and blossom end problems. Mulch and steady moisture help, within any local water rules.
Cold nights slow ripening, and frost ends production for all of these crops. Check the forecast in the weeks before your average first fall frost. If frost is coming, pick mature fruit and consider covering plants for a night or two if the long range forecast is mild.
What should you do with green fruit before frost?
Mature green tomatoes can finish ripening indoors, though flavor is usually not as good as vine ripened fruit. Choose fruit that has reached full size and shows a slight color change, and discard cracked or damaged fruit.
University of Wisconsin Extension notes that chilling can injure several of these crops, with ripe tomatoes showing water soaking and green tomatoes ripening poorly after cold exposure. Avoid cold storage for tomatoes unless your extension office advises otherwise, and keep other chilling sensitive crops out of the refrigerator for long periods.
How should you handle fruit vegetables after picking?
Handle gently, since these crops bruise easily. Keep them out of direct sun, and move them to a shaded, ventilated place. Use a clean container, and avoid piling too deep.
If you plan to can, freeze, pickle or dry what you grow, use tested recipes from the National Center for Home Food Preservation or your extension office. Guidance on acidity and processing matters for safety, and we do not list times or temperatures here.
What records are worth keeping?
Note first picks, peak weeks, and the date of your first frost. If a variety performed badly in heat or cracked often, write that down. Over a few seasons, you will know which varieties suit your site.
If you grow to sell, ask your extension office about grade standards and food safety training required in your state.
