Dwarf Key Lime Transplant Shock: Overwatering in Oversized Pot

Problem Sequence

Amanda's dwarf key lime: thrived in small pot, transplanted to 10-gallon plastic pot (Miracle-Gro soil). Since then: no growth, leaves browning from edges inward, dropping at 1/4 leaf progression.

Root Cause: Pot Size Mismatch

"When transplanting into a larger pot, the plant in the center stays wetter longer, causing drowning." Pots dry outside-in; roots haven't filled new volume.

Correct Watering for Up-Potted Plants

• Water around edge mostly until roots colonize new soil
• Occasional full soak
• Winter: even less water (slower drying)
• Saucer drainage: Empty within 15 minutes

Diagnostic Sign

Brown leaf tips = classic overwatering indicator

Soil Concern

Kathy notes customer reports: "Miracle-Gro is killing their plants" — likely the fertilizer-amended version causing salt buildup/root burn in containers.

Recovery Steps

1. Drastically reduce watering frequency
2. Edge-watering technique
3. Ensure saucer empty
4. Consider repotting to smaller intermediate size
5. Switch to unfertilized, well-draining mix
