Magnolia

Why is my magnolia tree losing its leaves?

Magnolias often drop leaves when they experience sudden changes in their environment or moisture levels. Check your soil moisture first to see if the roots are too dry or sitting in standing water.

Check these first

  1. Feel the soil 3 inches down to see if it is bone dry.
  2. Inspect the base of the trunk for signs of standing water.
  3. Check the leaves for signs of pests like scale.

Likely causes

  1. Drought stress

    Most likely

    How to tell: The leaves turn brown at the edges and feel brittle before falling off. This happens when the tree does not get enough water during hot, dry spells.

    What to do: Water the tree deeply once a week, ensuring the moisture reaches 6 to 10 inches into the soil. Apply a 3 inch layer of mulch around the base to help the soil hold onto that moisture.

  2. Transplant shock

    Most likely

    How to tell: The tree drops leaves shortly after being moved or planted in a new spot. It is a common reaction to root disturbance.

    What to do: Keep the tree well watered and avoid fertilizing for the first 6 months. Give the plant time to establish its roots in the new location.

When to worry

It is normal for evergreen magnolias to drop some older leaves in the spring. You should worry if the tree is losing green, healthy leaves rapidly during the growing season.

Stopping it coming back

Maintain a consistent watering schedule and keep the root zone mulched to prevent moisture swings.

Questions people ask

Will my magnolia grow its leaves back?
Yes, if the cause is corrected, the tree will produce new growth in the next growing season. Be patient while the tree recovers.
Should I fertilize a tree that is dropping leaves?
No, avoid fertilizing a stressed tree. It can push the plant to grow when it needs to focus on root repair.
