Mealybug Eradication on Hindu Rope Hoya Without Repotting

Hindu Rope 1

Hindu Rope 2 Hindu Rope Hoya (Hoya carnosa) has mealybugs in curly foliage. Alcohol-spray treatment (per prior advice) improved but didn't eradicate. Owner considers repotting due to soil contamination concern.

Soil Treatment Alternative

Mealybugs unlikely in soil. For small plants: fill sink with water/alcohol/soap solution, submerge entire pot (plant and soil) for ≤1 minute. Rinse plant and flush soil with clear water. Resolves issue without repotting.

Do NOT repot—worsens stress.

Addressing Root Causes

Pests target stressed plants. Hoya needs:

• Tight pot (potbound)
• Very sunny window
• Soil dry at least halfway down before watering (use wooden dowel, not moisture meter)
• Occasional pruning
• Remove all dead/discolored leaves
