root mealybugs on String Of Pearls
Quick answer
If your String Of Pearls has root mealybugs, the most likely cause is: String of Pearls mealybug infestations persist despite surface alcohol treatments because root-zone colonies remain undisturbed beneath the soil line. The succulent's shallow, fibrous root system provides ideal habitat for root mealybugs (Rhizoecus spp.) to feed on root hairs and stored nutrients. Compacted soil in pots older than 12 months harbors egg clusters and creates anaerobic conditions that weaken the plant's natural pest resistance.
Start here:
- 1. Root excavation: Gently unpot plant and rinse entire root ball under lukewarm water to expose hidden mealybugs; use soft brush to dislodge eggs from root hairs
- 2. Root treatment: Soak roots in 3% hydrogen peroxide diluted 1:10 with water for 10 minutes to oxygenate and kill root-zone pests
