overwatering and Croton
Quick answer
If overwatering is what's going on with your Croton, the most likely cause is: Croton root rot develops when soil remains waterlogged for 5+ days, creating anaerobic conditions that promote Pythium and Fusarium fungal growth. Unlike drought-tolerant succulents, crotons have fine, fibrous root systems requiring oxygen exchange between waterings. Overwatering - watering before top 2 inches of soil dry - causes root tissue to suffocate and decay. Early signs include yellowing lower leaves, wilting despite wet soil, and reduced variegation. Advanced rot produces foul-smelling soil, mushy stems at base, and complete leaf drop. Root rot progresses rapidly in standard potting soil without drainage amendments.
Start here:
- 1. Stop watering immediately and allow soil to dry completely
- 2. Unpot plant and inspect roots - healthy roots are white/firm; rotted roots are black/mushy/foul-smelling

How to correct overwatering on Croton
- 1
Stop watering immediately and allow soil to dry completely
- 2
Unpot plant and inspect roots - healthy roots are white/firm; rotted roots are black/mushy/foul-smelling
- 3
Trim ALL rotted roots with sterile scissors until only firm white tissue remains
- 4
Repot in fresh well-draining mix: 50% potting soil + 30% perlite + 20% orchid bark
- 5
Water only when top 2-3 inches of soil are completely dry; use moisture meter for accuracy
Keep overwatering from repeating on this Croton
Water only when top 2 inches dry - use finger test or moisture meter. Ensure pot has multiple drainage holes. Use terracotta or unglazed ceramic pots that wick excess moisture. Avoid self-watering devices. Never let pot sit in standing water.
