Chronic Leaf Deformation on Indoor Citrus

A dwarf lemon tree in Canada has had deformed, curled new growth for over a year. Owner worries about winter survival.

Cause: Citrus Leaf Miner

The curling is caused by leaf miner moth larvae tunneling in leaves. Cold weather stops the pest; new leaves emerge normal in spring.

Spray 100% pure neem oil on new growth every 7 days during active season. Neem oil is organic, doesn't wash off, and also works as fungicide and miticide. Only reapply to new leaves.

Winter Care

Keep tree alive with minimal water, bright light, and cool temperatures. Leaf miner goes dormant in cold.
