Phalaenopsis Sticky Leaves & Spike Death: Mealybugs, Not Soap Damage

Sticky Film = Mealybug Honeydew

Soapy water cleaned leaves temporarily but missed undersides where mealybugs hide. They suck sap, excrete sticky honeydew, weaken plant. Spike yellowed/blackened = mealybug damage + possible secondary fungus from evening spraying.

Mealybug Check & Cure

  1. Inspect undersides of all leaves for white cottony spots.
  2. If found: unpot, remove all mix, alcohol dip (50/50), wipe thoroughly.
  3. Repot in new pot + fresh mix.
  4. Systemic insecticide drench (imidacloprid) for insurance.

Spraying Timing Matters

Only spray/water in morning. Wet leaves overnight = fungus (black soot). If fungus present: wipe off, dust with cinnamon (antifungal).

If Not Mealybugs

Evening spraying → fungus → black soot → spike death. Same fix: morning only, cinnamon on spots.

Bottom Line

Check leaf undersides NOW. Mealybugs kill slowly but surely. Full cleanup + repot is the only sure cure.
