Arborvitae Decline in Containers: Root Restriction and Rot

Container Limitations for Large Evergreens

A gardener has 5 arborvitae in 2.5-foot-wide pots for 5 years, now browning/yellowing underneath, one lost. Advised "pot rot" with no solution. Trimmed tops already.

Two Fatal Container Problems

1. Root restriction – No room for new root growth; old roots die without replacement space
2. Potential root rot – Check drainage; arborvitae hate excess water

Ed Gulliksen states plants this size should be in ground, not pots. Containers only temporary. Top trimming doesn't address root issues.
