Red, Misshapen, Soft Canes on Shrub Roses = Rose Rosette Disease

Fast-growing deep red canes with distorted, curled red leaves = Rose Rosette Disease (RRD), caused by a virus vectored by eriophyid mites. No cure. Infected plants must be removed entirely (roots and all) and burned or bagged for trash. Do not compost. Nearby roses at high risk.
