European crabapple · Malus sylvestris

Why is my European crabapple losing its leaves?

It is less common for this tree to drop leaves suddenly, so this usually points to environmental stress or a severe pest issue. Check your soil moisture and inspect the undersides of leaves for insects first.

Check these first

  1. Check the soil moisture level around the root zone.
  2. Inspect the undersides of leaves for small insects.
  3. Look for signs of wilting or crispy leaf edges.

Likely causes

  1. Drought stress

    Most likely

    How to tell: The leaves turn brown or crispy at the edges before falling off during a dry spell. The soil feels bone dry several inches down.

    What to do: Water the tree deeply once a week to ensure moisture reaches the root zone. Apply a 2 to 3 inch layer of mulch around the base to help retain water.

  2. Aphid infestation

    Possible

    How to tell: You will see small insects on new growth and sticky honeydew on the leaves. The leaves may curl or yellow before dropping.

    What to do: Spray the foliage with a strong stream of water to knock the aphids off. If the problem persists, apply insecticidal soap according to the label instructions.

Stopping it coming back

Maintain a consistent watering schedule during dry periods and keep the tree healthy with proper sunlight.

Questions people ask

Can overwatering cause leaf drop?
Yes, if the roots sit in soggy soil for too long, they can suffocate and cause the leaves to drop. Ensure your tree is planted in well draining soil.
Should I fertilize a tree that is losing leaves?
No, avoid fertilizing a stressed tree as it can cause further damage. Wait until the tree has recovered and is showing new growth.
