Plant problems

Curling leaves

Curling is a protective response, not a diagnosis on its own.

Moisture

Both dry roots and damaged wet roots can reduce water reaching the leaf.

Temperature

Heat, cold glass and draughts may trigger curling.

Pests

Mites, aphids and thrips can distort young or established leaves.

Problem

What to do next

  1. 1

    Photograph the whole plant and the affected leaves.

  2. 2

    Check the root zone and recent temperature changes.

  3. 3

    Inspect new growth and leaf undersides before choosing a treatment.

Observation

When to act sooner

  • New leaves emerge severely distorted.
  • Curling spreads to nearby plants.
  • The stem base is soft or dark.
Important

Curling leaves can have several causes. Confirm the plant, conditions and recent care before choosing a treatment.
