Why are my curry leaf tree leaves curling?

Check these first

1. Inspect the undersides of curled leaves for tiny insects.
2. Check if the curling happens only during the hottest part of the day.
3. Feel the soil to see if the plant is thirsty.

Likely causes

1. Asian Citrus Psyllids

   Most likely

   How to tell: You will see small bumps or galls on the leaves and the foliage will look twisted or curled. These pests hide on the underside of leaves.

   What to do: Prune off the heavily infested leaves and dispose of them in the trash. Spray the tree with neem oil or insecticidal soap every 7 days until the infestation clears.

2. Heat Stress

   Possible

   How to tell: The leaves curl inward during the hottest part of the day but look normal again in the cool morning. This is a protective response to prevent moisture loss.

   What to do: Move the pot to a spot with afternoon shade if the sun is too intense. Ensure you water deeply whenever the top inch of soil feels dry.

When to worry

Worry if the curling is accompanied by yellowing or stunted growth. It is normal for leaves to curl slightly when the tree is adjusting to a new, very sunny location.

Stopping it coming back

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

Questions people ask

Can I still use the leaves if they are curled?

If the curling is caused by psyllids, it is best to discard the affected leaves. If it is just heat stress, the leaves are safe to use.

Will neem oil hurt my tree?

Neem oil is safe for curry leaf trees when applied in the evening. Avoid spraying during the heat of the day to prevent leaf burn.
