Yellowing Leaves — Nitrogen Deficiency in Cucumber

Commonly affects: Cucumis sativus (Cucumber)

Older leaves turn pale yellow-green uniformly while new growth stays healthier, and overall vine vigour and fruit production slow.

Potential Causes

  1. 1Insufficient nitrogen for this fast-growing, heavy-feeding vine
  2. 2Heavy rain leaching nutrients from the root zone
  3. 3Depleted soil that hasn't been fed recently

Solution Steps

  1. 1Apply a balanced, nitrogen-rich fertiliser at the base of the plant
  2. 2Side-dress with compost during active vine growth
  3. 3Feed every 2-3 weeks through the growing season
  4. 4Shift toward a lower-nitrogen, fruit-focused feed once flowering begins

Prevention Tip

Cucumbers are vigorous, fast-growing vines that benefit from regular feeding through the season rather than a single application at planting.
