Diagnosing a Dying New Rose Bush and Caring for Its Healthy Companion

One of your two newly planted rose bushes is thriving while the other is browning and dying from the inside out. The diagnosis is clear: you purchased a rose that was already dead or mortally damaged.

Why the Bush Was Dead at Purchase

Roses damaged by cold during storage or transit often show green canes externally while the internal tissue is dead. Once planted and warmed, the dead tissue dries and turns brown—the "delayed death" phenomenon. This is a nursery/retail issue, not your fault.

Action for the Dead Bush

• Return it to the seller for replacement (most guarantee their plants)
• Do not attempt to revive it—no amount of care will help

Care for the Healthy Bush

Watering: Every 3 days initially, then every 5 days once established. Increase to every 2 days during heat waves. Soil should be damp, not soggy.

Fertilizing: Monthly application of rose fertilizer around the base until end of July. Stop fertilizing by August to allow hardening off for winter.

Mulching: 2–3 inches of organic mulch around the base conserves moisture, cools roots, and reduces watering frequency.

Your healthy bush has an excellent prognosis with this routine. The replacement should establish equally well.
