First-Time Rose Care: Yellow Leaves, Black Spot, and Recovery

New Kansas City Gardener's Rose Problems

Inherited roses (3 wild, 3 climbers, few miniatures) bloomed well, then yellowed leaves, black spots, sparse foliage after feeding, pruning, deadheading, and insect spray.

Diagnosis

• Stress response: Weather change, spraying in heat, or over-fertilizing caused yellowing.
• Black spot: Fungal disease—common, treatable.

Action Plan

1. Don't prune canes—only leaves are affected. Roses grow 3 leaf sets per season.
2. Spray fungicide (Ortho Rose Defense) for black spot.
3. Water deeply, avoid wetting foliage.
4. Hold fertilizer until healthy growth returns.

Follow-Up

New healthy leaves will replace yellow ones. Blooms will resume.
