Transplant Shock on calathea
What's Happening
Calathea experience severe transplant shock due to their fibrous, delicate root systems that are easily damaged during repotting. The plant redirects all energy to root repair, causing temporary leaf browning, curling, or stunted growth. Shock is exacerbated by changing multiple variables simultaneously (pot size, soil type, light, humidity). Unlike hardy plants, Calathea may take 4-8 weeks to show recovery signs post-transplant.
How to Fix It
- 1
Minimize root disturbance - keep root ball intact as much as possible
- 2
Only increase pot size by 1-2 inches maximum
- 3
Use identical soil composition to previous pot
- 4
Maintain high humidity (70%+) for 2-4 weeks post-repot
- 5
Avoid fertilizing for 6-8 weeks to prevent root burn
How to Prevent It
Repot only when rootbound (roots circle pot bottom). Best timing: spring when actively growing. Pre-moisten new soil. Match new pot material to old (terracotta vs plastic).
