Curling Leaves on Potted Calamondin: Citrus Leafminer Cycle

Gift Calamondin in Michigan has curled leaves from day one. No bugs visible. Outdoors all summer, no improvement. Grew citrus successfully in Florida. Different situation—need advice.

Diagnosis: Citrus Leafminer

The curling + silvery trails = citrus leafminer (Phyllocnistis citrella). Larvae mine inside leaves. In Florida, they cycle seasonally: active summer, dormant winter, new clean growth in spring.

Management Options

• Accept it: Cosmetic only. Tree fruits fine. I grow organically—never lost a tree.
• Remove bad leaves: But may lose fall fruit
• Spray oil/spinosad every 7 days on new flush—labor intensive
• Companion plant: Orange jasmine (if legal) as trap crop

Michigan Specifics

Indoors in winter: leafminer may persist. Provide bright light, cool temps, reduced water. Move out after frost.

Your tree is healthy. Leafminer is a nuisance, not a threat.
