Rose Canker and Possible Spider Mites: Prune, Sterilize, Spray Neem

Second-year 'Cariad' shrub rose has blackish-red speckles on stems, one brown, one yellow/dead.

Canker Treatment

• Mix 1 part bleach : 10 parts water.
• Cut each affected stem well below diseased area.
• Dip pruners in bleach between every cut.
• Trash all diseased wood—do not compost.

Check for Spider Mites

Tap leaves over white paper; moving specks = mites. Spray neem oil thoroughly, repeat 3–4 times at 5–7 day intervals. Inspect nearby plants.

Vigilance prevents recurrence.
