Why does my Burning bush have pests?

Burning bushes are prone to scale insects and powdery mildew, which can weaken your shrub over time. Check the undersides of leaves and along the stems for any signs of these invaders.

Check these first

  1. Inspect the stems for small, raised brown bumps.
  2. Look for white, powdery patches on the leaf surfaces.
  3. Check if the leaves look yellow or stunted.

Likely causes

  1. Scale Insects

    Most likely

    How to tell: You will see small, brown, bump like growths on the stems or undersides of leaves. These insects suck sap and cause yellowing or stunted growth.

    What to do: Scrape off light infestations with a soft brush or fingernail. For larger issues, apply horticultural oil or neem oil spray to the affected areas every 7 to 10 days until they are gone.

  2. Powdery Mildew

    Most likely

    How to tell: This fungal issue looks like a white, dusty coating on the surface of the leaves. It usually happens when there is poor air circulation or high humidity.

    What to do: Prune back crowded branches to improve airflow through the center of the bush. Apply a fungicide labeled for powdery mildew if the infection covers more than 20 percent of the foliage.

When to worry

Worry if you see the shrub losing vigor or if the pests are spreading to every branch. It is normal to see a few insects occasionally, but a heavy infestation requires immediate action.

Stopping it coming back

Keep the shrub healthy with proper watering and prune annually to ensure good air circulation. Avoid overhead watering which can encourage fungal growth.
