Why does your Mini Rose Desert Ovation have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are small, soft-bodied insects that pierce the tender new growth of mini roses to suck sap. They excrete a sugary substance known as honeydew, which creates the sticky residue on the leaves.
Scale insects attach themselves to the stems and leaves of mini roses, feeding on phloem sap. Like aphids, they excrete honeydew that coats the foliage in a sticky film.
These pests thrive in the sheltered crevices of compact mini rose varieties. They produce honeydew as they feed, often accompanied by a white, cottony appearance around the leaf axils.
While not a pest itself, sooty mold is a black fungus that grows directly on the sticky honeydew left by insects. It can eventually coat the 'Desert Ovation' leaves, blocking sunlight.
