Aphid Infestation

Aphids are common pests on Lady Banks' Rose that suck sap from tender new growth, excreting a sugary substance known as honeydew. This honeydew creates the characteristic sticky film on leaves and stems.

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaves of Rosa banksiae and feed on phloem sap. Like aphids, they excrete honeydew which leads to stickiness and can eventually promote the growth of black sooty mold.

Very Common

How to confirm: Look for small, stationary bumps or shell-like growths firmly attached to the rose canes.

Sooty Mold

While not a primary cause of stickiness, sooty mold is a fungus that grows on the honeydew left by sap-sucking insects. It appears as a black, velvety coating that can obscure photosynthesis in the climbing rose.

Common

How to confirm: Check if the sticky residue is accompanied by a dark, charcoal-colored fungal growth covering the leaf surface.
