Spider Mites on Lemon Tree

Commonly affects: Citrus limon (Lemon Tree)

Fine yellow stippling spreads across leaves, with fine webbing visible on the underside in heavier infestations, especially in hot, dry conditions.

Potential Causes

  1. 1Hot, dry conditions favouring rapid mite reproduction, particularly for trees kept indoors during winter
  2. 2Dusty leaves providing a hospitable surface
  3. 3Drought-stressed trees being more vulnerable

Solution Steps

  1. 1Rinse the plant thoroughly with a strong water spray, focused on leaf undersides
  2. 2Apply insecticidal soap or neem oil, repeating every 5-7 days
  3. 3Increase humidity around indoor-grown trees, since mites struggle in more humid conditions
  4. 4Maintain consistent watering, since drought stress increases susceptibility

Prevention Tip

Indoor-grown lemon trees in dry winter heating are especially prone to spider mites — a periodic misting or humidity boost helps discourage them.
