Why does my White mulberry have pests?

White mulberries are tough trees, but they can occasionally attract scale insects that sap their strength. Check your branches closely for small, bumpy growths that look like tiny shells.

Check these first

  1. Inspect the undersides of leaves and along the stems for bumps.
  2. Check for sticky honeydew on the leaves or ground below.
  3. Look for fine webbing between the branches.

Likely causes

  1. Scale insects

    Most likely

    How to tell: Look for small, brown or tan bumps on the stems and undersides of leaves. These insects stay stationary and suck sap, often leaving behind a sticky residue called honeydew.

    What to do: Scrub the branches gently with a soft brush and a mixture of water and mild dish soap. For larger infestations, apply horticultural oil during the dormant season to smother the pests.

  2. Spider mites

    Possible

    How to tell: You will see fine webbing between leaves and tiny yellow stippling on the foliage. They thrive in hot, dry weather.

    What to do: Spray the tree with a strong stream of water to knock the mites off. If the problem persists, use neem oil every 7 to 10 days until they are gone.

When to worry

Small numbers are usually manageable, but heavy infestations that cause significant leaf yellowing require immediate treatment. A few insects are normal, but a full colony will weaken the tree.

Stopping it coming back

Keep your tree healthy with proper watering and regular pruning to ensure good airflow. Healthy trees are much better at resisting pest attacks on their own.

Questions people ask

Will these pests kill my tree?
Usually no, but they can cause branch dieback and weaken the tree over time. Treating them early keeps your mulberry thriving.
Can I use chemical sprays?
It is better to use gentle methods like horticultural oil or soap first. Chemicals can harm beneficial insects that naturally hunt these pests.
