Southern dewberry · Rubus trivialis

Why is my Southern dewberry dropping its leaves?

It is less common for Southern dewberries to drop leaves, as this usually signals a major environmental shift or a pest infestation. Check the undersides of the leaves for aphids first.

Check these first

  1. Look closely at the undersides of the leaves for tiny bugs.
  2. Check the soil to see if it has been dry for too long.
  3. Inspect the fallen leaves for spots or discoloration.

Likely causes

  1. Aphid Infestation

    Most likely

    How to tell: You see small clusters of insects on the new growth and the leaves are sticky or yellowing before they fall.

    What to do: Spray the aphids off with a strong stream of water from your hose. If they persist, use an insecticidal soap once a week until they are gone.

  2. Severe Drought

    Possible

    How to tell: The leaves turn yellow or brown and fall off in large numbers during a dry spell.

    What to do: Increase your watering frequency to every 3 to 5 days during hot weather. Ensure the water penetrates deep into the root zone.
