Citrus Leaf Curl in Miami: Leaf Miner and Sun Requirements

New Citrus Trees with Curled Leaves

Lemons, key limes, grapefruits planted in sandy soil amended with cow manure. Leaves curl closed like a book. Owner asks about sun needs (30% shade).

Cause: Citrus Leaf Miner

Moth larvae tunnel in leaves. Stops when weather cools; new leaves emerge clean. No treatment needed—owner gets good fruit without spraying.

Sunlight

30% shade is fine. Key limes everbearing—patience. New trees focus on roots first. Ensure not planted deeper than in pot (old soil visible). No mulch/plants/stones under canopy. Minimum 3 inches water/week.
