Why does your Crassula mesembrianthoides subsp. hispida have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Scale insects attach to the stems and undersides of Hairy Crassula leaves, secreting 'honeydew,' a sticky substance. This sugary waste often attracts secondary issues like sooty mold.
Mealybugs produce honeydew while feeding on the plant's sap, which creates a sticky residue. They are particularly well-camouflaged within the fine hairs of this specific subspecies.
Aphids are soft-bodied insects that pierce plant tissues to suck sap, leaving behind sticky honeydew. This can cause the fine hairs of the Crassula to appear clumped together.
In rare cases of physical damage or extreme temperature fluctuations, the plant may exude sap that dries into a sticky film.
