Slimy Orchid Leaves and Leaf Bumps: Slugs, Scale, and Repotting Rescue

Diagnosing Two Problems

Slimy film on leaves = slugs/snails in the potting mix. Small bumps on leaf undersides = likely scale insects. Both weaken the plant and prevent blooming.

Immediate Action Plan

1. Confirm scale: try removing bumps with alcohol-dipped Q-tip. If they come off, it's scale.
2. Remove all visible scale with alcohol.
3. Apply systemic insecticide spray for hidden crawlers and eggs.
4. Repot in fresh mix—clean roots thoroughly to evict slugs/snails.
5. Monitor for reinfestation.

Blooming Potential

If it's Phalaenopsis, spring repotting can still allow blooming this season. Healthy roots = future flowers.
