Troubleshooting Dying Stems on Newly Planted Double Knock Out Roses

If stems die back after planting, the cause may be unaged cow manure burning the roots. Large container roses should not suffer transplant shock if watered properly. Water deeply with a bucket every three days rather than brief daily sprinklings. If the roses were purchased locally and you followed proper planting procedures, the nursery should replace them under warranty.

Key Steps

Ensure manure is fully composted before use.
Water deeply and infrequently.
Contact the garden center for replacement if the plants fail despite correct care.
