Mini Rose Corn Jewel Sticky Leaves - Causes & Fixes

Aphid Infestation

Aphids are small, soft-bodied insects that pierce the tender new growth of miniature roses to suck sap. As they feed, they excrete a sugary substance known as 'honeydew,' which creates the sticky residue on leaves and buds.

Very Common

Very Common
