Saving Your Money Tree from Scale Insects: Proper Treatment and Care Adjustments

Diagnosis: Scale, Not Disease

Brown spots and stickiness are classic signs of scale insects, not a disease. The infestation likely came with the plant. The shop’s remedy (soap + alcohol) had the right ingredients but wrong proportions and application method.

Correct Treatment

1. Mix 5 parts water : 1 part rubbing alcohol + a squirt of liquid dish soap.
2. Thoroughly drench ALL leaf and stem surfaces until dripping. This reaches hidden crawlers.
3. Repeat in 5–7 days to catch newly hatched nymphs.
4. Optionally, wipe off dead scales to monitor for reinfestation.

If That Fails

Try Brand X Foliage Cleaner (silicon-based, penetrates crevices). Available from Southwest Plantscape Products (1-800-333-7977, www.southwestplantscape.com).

Care Corrections

• Stop overwatering: The repotting into a larger pot was a mistake. Allow the top quarter of soil to dry between waterings.
• Light: Bright indirect light is best.
• Fertilizer: Hold off until the plant recovers.

Key Point

Scale treatment requires complete coverage and persistence. Fixing the cultural conditions (pot size, watering) is equally important for long-term health.
