Camellia sinensis Sticky Leaves - Causes & Fixes

error

Aphid Infestation

Aphids are small, soft-bodied insects that pierce the tea plant's tender new growth to suck sap, excreting a sugary substance known as honeydew. This honeydew creates the characteristic sticky film on the leaf surfaces.

Very Common

Sooty Mold Development

While not a direct cause of stickiness, sooty mold is a black fungus that grows on the honeydew left by sap-sucking insects. This creates a dark, crusty layer over the sticky residue on the tea leaves.

Common

How to confirm: Check if the sticky residue is accompanied by a black, powdery coating that can be wiped off with a cloth.
