New Gardener's Black Spot Crisis: Hard Prune, Soaker Hose, Resistant Varieties

North East Texas. 3 established roses blooming heavily, then black spot discovered after daily sprinkler watering. New bushes purchased. Action plan:

Immediate Triage

1. Infected bush: Cut to 12" (6+" above graft), strip ALL leaves. Won't kill it—roses rebound from 1' stumps.
2. Stop sprinklers on roses. Soaker hose only—deep water, dry foliage.
3. Preventive spray on healthy bushes (garden center fungicide).

Planting New Bushes

• Full sun, open area (no walls/fences within 4–5').
• Space for mature size—foliage must not touch.
• Air circulation = disease prevention.

Pot vs. Ground

Large pots (24"+) work but need daily watering in heat. Mulch 2–3". Ground better if staying long-term.
