Chinese Wisteria · Wisteria

Why is my Wisteria losing its leaves?

It is less common for Wisteria to drop leaves, usually caused by sudden environmental stress or a borer infestation. Check your vine for small holes in the stems near the base first.

Check these first

  1. Inspect the main stems for small entry holes or sawdust.
  2. Check the soil moisture level with your finger.
  3. Look for signs of wilting on specific branches.

Likely causes

  1. Wisteria Borer

    Possible

    How to tell: You will see small holes in the main stems or branches where larvae have tunneled inside. The foliage above these holes will wilt and drop prematurely.

    What to do: Prune out and destroy any infested branches immediately to stop the spread. You can apply a systemic insecticide labeled for borers to the soil around the base in early spring.

  2. Extreme Drought

    Possible

    How to tell: The leaves will turn crispy and brown before falling off during a hot, dry spell. The soil will feel bone dry several inches deep.

    What to do: Deeply water the plant until the soil is moist at least 6 inches down. Apply a 2 to 3 inch layer of mulch around the base to help hold that moisture in.

When to worry

It is normal for Wisteria to drop all its leaves in late autumn as it prepares for winter. Be concerned if leaves fall during the peak of summer.

Stopping it coming back

Keep your vine healthy with consistent watering and avoid wounding the main trunk with lawn equipment.

Questions people ask

Will my Wisteria grow back after losing leaves?
If the roots are healthy and the borer damage is minor, it will likely push out new growth next season. Keep it watered and watch for new shoots.
Can I fertilize a stressed Wisteria?
No, wait until the plant shows signs of recovery. Fertilizer can burn roots that are already struggling.
