Mountain Laurel · Kalmia latifolia

Why is my Mountain Laurel losing its leaves?

It is less common for Mountain Laurel to drop leaves, and this usually happens when the plant is suffering from severe root stress or a sudden change in its environment. Check the soil condition first to ensure it is not waterlogged or completely dried out.

Check these first

  1. Check the soil for signs of waterlogging.
  2. Look for any recent changes in the plant's location.
  3. Inspect the base of the stems for softness.

Likely causes

  1. Root Rot

    Possible

    How to tell: Leaves turn yellow or brown before falling off, and the stems may feel soft. This is caused by roots sitting in standing water for too long.

    What to do: Repot the plant into fresh, well-draining soil and trim away any mushy, dark roots. Adjust your watering schedule to ensure the soil stays moist but not soggy.

  2. Environmental Shock

    Possible

    How to tell: Leaves drop suddenly after you move the plant to a new location with different light or temperature. The plant is reacting to the change in conditions.

    What to do: Keep the plant in a stable environment with consistent bright indirect light. Avoid moving it frequently so it can adjust to its surroundings.

When to worry

Losing a few older leaves near the base is normal as the plant grows. However, if healthy leaves are dropping from the top or middle, it is a sign of a serious problem.

Stopping it coming back

Avoid sudden changes in light or temperature and ensure the soil has excellent drainage to prevent root issues.
