Sunscald on Cucumber Fruit

Commonly affects: Cucumis sativus (Cucumber)

A pale, bleached patch develops on the side of fruit facing direct sun, especially after sudden exposure from pruning or foliage loss.

Potential Causes

  1. 1Sudden exposure to intense sun after over-pruning removed sheltering leaves
  2. 2Foliage loss from disease exposing previously shaded fruit
  3. 3A heatwave following cooler, cloudier weather

Solution Steps

  1. 1Avoid removing excessive foliage at once when pruning or training vines
  2. 2Address any foliar disease causing leaf loss promptly
  3. 3Provide temporary shade cloth during extreme heat
  4. 4Harvest affected fruit promptly since scald increases rot risk

Prevention Tip

Sunscald is usually secondary to foliage loss — keeping the vine healthy and well-covered prevents most cases.
