Boxwoods Turning Yellow: Root Rot from Overwatering

April-planted boxwoods in new bed; some yellow, two fully yellow. Fertilized with Miracle-Gro in June. Leaky faucet nearby fixed weeks ago.

Diagnosis: Root Rot / Boxwood Decline

• Boxwoods hate wet feet; leak caused waterlogging.
• Check roots: dark, mushy = rot.
• Boxwood decline = multiple soil fungi.

Treatment Attempt

• Daconil fungicide: 2% solution, ½ gallon per plant, repeat 14 days.
• Fungicide preventive, not curative—may not save them.
• Don't overwater; replace dead plants in fall.

Fertilizer burn possible but wet soil primary culprit.
