Why does my Multiflora rose have pests?

Multiflora roses are magnets for tiny visitors that can cause significant damage to your plant. Check the undersides of your leaves and the new growth for signs of infestation.

Check these first

  1. Inspect the new growth for abnormal red, witch broom clusters.
  2. Look for tiny insects on the undersides of leaves or near flower buds.
  3. Check for sticky residue on the foliage.

Likely causes

  1. Eriophyid Mites

    Most likely

    How to tell: These microscopic mites cause Rose Rosette Disease, which shows as distorted, bright red, witch broom growth on stems. You will not see the mites themselves, but the twisted, rapid growth is a telltale sign.

    What to do: Prune out all infected branches immediately, cutting well below the distorted growth. Sterilize your pruners with rubbing alcohol between every single cut to avoid spreading the virus to healthy canes.

  2. Aphids

    Most likely

    How to tell: You will see clusters of tiny green or pink insects on the flower buds and tender new leaves. They often leave behind a sticky substance called honeydew.

    What to do: Blast the aphids off with a strong stream of water from your garden hose. If they persist, apply insecticidal soap directly to the colonies every 5 to 7 days until they are gone.

When to worry

If you see the witch broom growth of Rose Rosette Disease, the plant is likely beyond saving and should be removed entirely. Minor aphid populations are normal and usually resolve on their own.

Stopping it coming back

Keep your rose healthy with proper spacing to improve airflow and avoid overhead watering. Regularly inspect your plants during the growing season to catch issues early.
