When to harvest cucumbers

Pick at the size the variety is meant to be: about 8 cm (3 in) for mini types, 15 cm (6 in) for small ones and 20–25 cm (8–10 in) for full-size slicers.(RHS)
Good fruit is evenly green and firm. Yellowing, swollen or soft fruit is past its best.(RHS)

How often to pick

Check every few days, and cut rather than pull the fruit off. Regular picking keeps the plant producing.(RHS)

How many cucumbers to expect

A 3 m (10 ft) row typically gives about 5.4 kg (12 lb).(Montana State University Extension)

Yields vary with variety, weather, soil and care. Treat these as ballpark figures, not targets.

Plan for your family

For 4 people eating cucumbers fresh, plan on about 8–12 hills (small groups of plants)(University of Missouri Extension).

To preserve or store some as well, allow 3–5 hills per person.(University of Missouri Extension)

Storing your cucumbers

Store at around 13 °C (55 °F) in a perforated bag. A few days in the fridge is fine, but colder than about 4 °C (40 °F) causes pitting and watery patches.(University of Minnesota Extension)
Keep cucumbers away from apples and tomatoes. Expect about a week.(University of Minnesota Extension)

Cucumber harvest FAQ

What size should I pick cucumbers?

It depends on the type. The RHS suggests about 8 cm for mini cucumbers, 15 cm for small-fruited varieties and 20–25 cm for full-sized ones. Pick before they turn yellow or soft.

Why do my cucumbers go soft in the fridge?

Cucumbers are sensitive to cold. University of Minnesota Extension notes they develop pitting and water-soaked spots below about 4 °C (40 °F), so a cool room or only a few days in the fridge is best.
