Citrus latifolia Sticky Leaves - Causes & Fixes

error

Aphid Infestation

Aphids are small, soft-bodied insects that pierce the lime tree's tender new growth to suck sap, excreting a sugary substance known as honeydew. This residue creates a sticky coating on the leaves and can lead to stunted growth.

Very Common

How to confirm: Inspect the undersides of young leaves and terminal buds for tiny green or black moving insects.

Scale Insects

Scale insects attach themselves firmly to the stems and leaf petioles of the Tahiti Lime, extracting nutrients and secreting honeydew. Over time, this buildup can cause a thick, sticky film on the foliage.

Very Common

Sooty Mold Development

While not a direct cause of stickiness, sooty mold is a black fungus that grows specifically on the honeydew left by pests. The presence of black, powdery patches on your lime leaves indicates an underlying sap-sucking insect problem.

Very Common

How to confirm: Check if the sticky residue is accompanied by a dark, charcoal-like coating that can be wiped off.

Whitefly Infestation

Whiteflies congregate on the undersides of citrus leaves and excrete honeydew as they feed. This results in sticky leaf surfaces and often causes leaves to drop prematurely if the infestation is heavy.

Common
