Olive tree · Olea europaea

Why is my olive tree losing its leaves?

Olive trees are evergreen, so seeing leaves fall is usually a sign that something is off with their environment. The most common culprit is either too much water or not enough sunlight.

Check these first

  1. Check the moisture level two inches deep in the soil.
  2. Verify the tree is getting direct sunlight for most of the day.
  3. Inspect the drainage holes to ensure they are not blocked.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil stays damp for weeks and the leaves turn yellow before dropping.

    What to do: Stop watering immediately and let the soil dry out completely. Ensure your pot has drainage holes and never let the tree sit in a saucer of water.

  2. Insufficient Light

    Most likely

    How to tell: The tree is in a dim corner and the leaves are dropping from the bottom up.

    What to do: Move the tree to a spot that gets at least 6 to 8 hours of direct sunlight. If you are indoors, place it right in front of your sunniest south facing window.

When to worry

It is normal for a few old leaves to drop occasionally, but heavy leaf loss is a serious sign of stress that needs immediate attention.

Stopping it coming back

Stick to a strict watering schedule where you let the soil dry out almost completely between waterings.
