Yellow Leaves on money tree
What's Happening
Yellowing leaves in Pachira aquatica result from insufficient light intensity (below 1000 lux) reducing photosynthetic capacity, combined with inadequate nitrogen availability. When light levels drop below tropical understory minimums (typically in north-facing windows or during winter), the plant cannot produce sufficient chlorophyll, causing nitrogen-starved lower leaves to yellow progressively. This differs from overwatering yellowing, which appears rapidly and affects multiple leaves simultaneously.
How to Fix It
- 1
Measure current light: Use phone light meter app or dedicated device - target minimum 1500 lux
- 2
Relocate to brighter indirect location or install full-spectrum grow light (12-14 hours/day)
- 3
Apply balanced fertilizer (10-10-10 at half strength) every 4-6 weeks during active growth
- 4
Allow top 2-3 inches of soil to dry between waterings; avoid cold water below 65°F
- 5
Remove fully yellowed leaves at base; monitor new growth for return to deep green color
- 6
If yellowing persists after 4 weeks, check roots for rot and repot if necessary
How to Prevent It
Maintain bright indirect light (2000-5000 lux measured with light meter); position within 3-5 feet of east/west windows; supplement with grow lights during winter months; fertilize monthly with balanced 10-10-10 at half strength during growing season; maintain consistent watering to prevent nutrient leaching.
