Do Anthuriums Like to Be Root Bound?
No. anthuriums stop blooming when severely root-bound. They prefer to be repotted every 2–3 years to keep their flower production going.
What happens to a root-bound Anthurium
Severely root-bound anthuriums stop blooming, produce smaller leaves, and decline in vigor.
When to repot anyway
When flowering stops despite good light, or rootball mounds above the pot rim.
Signs the plant is TOO root-bound
No flowers for 6+ months despite bright indirect light, soil dries within a day, rootball pushing out of pot.
