Citrus

Why are my citrus tree leaves curling?

Curling leaves on a citrus tree usually point to a pest infestation or a sudden change in environmental conditions. Check the undersides of the leaves for tiny insects first.

Check these first

  1. Inspect the undersides of curled leaves for pests.
  2. Look for silvery winding trails on the leaf surface.
  3. Check if the soil is extremely dry or waterlogged.

Likely causes

  1. Citrus Leaf Miner

    Most likely

    How to tell: You will see silvery, winding trails or tunnels etched into the surface of the leaves. The leaves often curl inward as the larvae feed inside the tissue.

    What to do: Prune away heavily infested leaves to stop the spread. Apply neem oil to the foliage every 7 to 14 days to deter the moths from laying more eggs.

  2. Aphids

    Most likely

    How to tell: These tiny, soft bodied insects cluster on new growth and cause leaves to curl and distort. You may also see a sticky residue called honeydew on the leaves.

    What to do: Spray the leaves with a strong stream of water to knock the aphids off. If they persist, use an insecticidal soap once a week until they are gone.

When to worry

Worry if the curling affects the majority of new growth or if the tree stops producing leaves. A few curled leaves on an older branch are usually not a major threat.

Stopping it coming back

Keep your tree healthy with consistent watering and inspect new growth weekly for early signs of pests.

Questions people ask

Will my leaves uncurl after I treat the pests?
No, leaves that have already curled will remain distorted. Focus on protecting the new, healthy growth that emerges after treatment.
Should I cut off all the curled leaves?
Only remove leaves that are severely damaged or infested. If the leaf is still green and attached, it can still help the tree produce energy.
