How often should zucchini be harvested?

Prof. Samuel Fitzgerald, Ph.D.The frequency of harvesting affects zucchini production and the health of the plant. During peak production, check plants every 48 hours for fruits that measure 6 to 8 inches (15 to 20 cm) in length. This prevents the development of fruit that is too large and which robs the plant of energy. The act of continual harvesting causes the plant to compensate by producing more flowers. This very much extends the harvest period.
Overgrown zucchinis slow production by stimulating hormones. Large fruits tell plants not to bloom. I learned this when I got a 40% reduction in harvest by going three days without picking. Pick large fruits right away to reset production, even if you compost them.
Cutting Method
- Use sharp pruners for clean cuts
- Leave 1 inch (2.5 cm) stem attached
- Prevents stem rot at attachment point
Timing Strategy
- Harvest early morning for crispness
- Avoid midday when plants are stressed
- Check plants every 48 hours minimum
Quality Inspection
- Glossy skin indicates freshness
- Firm flesh without soft spots
- No insect damage on underside
Methods of storage preserve freshness from harvest to harvest. Unwashed zucchinis will keep well for 7 to 10 days if stored in perforated bags in the refrigerator's crisper. For longer storage, cut into slices, blanch, and freeze. I preserve my summer surplus for winter soups and breads by this means.
Please don't throw away those oversized zucchinis; use them wisely! Grate the flesh for moist baked goods, stuffing, or soups. Hollow them out for floatable servings. They reduce waste while allowing the full use of mature vegetables that would otherwise go to waste to become sources of good food.
