Pachira (Money Tree) Brown Leaves: Mealybugs Then Mites

Phase 1: Mealybugs

White dots on leaf undersides + leaves turning brown and falling = mealybugs. Treatment: soap wash + 1–2 tbsp rubbing alcohol per quart water. Spray every 3–4 days until gone.

Phase 2: Spider Mites (Follow-Up)

Tiny bugs in soil + continued decline = spider mites. They thrive in dry, warm conditions. Alcohol-water soil drench helps. Better: repot in fresh soil, wash roots, spray foliage with neem oil or horticultural oil weekly for 3 weeks.

Lady Beetles?

Ladybugs eat aphids/scale, not mites. For mites, predatory mites (Phytoseiulus) are the biological control—but hard to use indoors.

Complete Reset (Best for Severe Cases)

1. Remove plant from pot.
2. Wash all soil off roots.
3. Dip entire plant in soap/alcohol solution.
4. Repot in fresh, sterile mix (2:1 soil:perlite).
5. Spray neem oil weekly × 3.
6. Increase humidity (mist, pebble tray)—mites hate humidity.

Prevention

• Inspect weekly with magnifier.
• Keep humidity up.
• Quarantine new plants.
• Don't over-fertilize (succulent growth attracts pests).

Your Pachira had a pest complex. The full reset gives it a clean start. Consistency with humidity and monitoring prevents recurrence.
