Why are my Brazil nut tree leaves turning yellow?

Yellowing leaves on a Brazil nut tree often signal that the plant is struggling with its water balance or light exposure. Check the soil moisture first to see if you are overwatering or underwatering.

Check these first

  1. Feel the soil moisture level with your finger.
  2. Check the drainage holes for blockages.
  3. Assess the amount of direct sunlight the plant receives daily.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow starting from the bottom of the plant, and the soil feels soggy to the touch.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so excess water can escape.

  2. Low Light

    Possible

    How to tell: Leaves lose their deep green color and turn a pale yellow, especially on the side facing away from the sun.

    What to do: Move your tree to a spot that receives full, direct sun for at least 6 to 8 hours a day. If you are growing indoors, use a high output grow light.

When to worry

It is normal for the oldest, lowest leaves to yellow and drop as the tree grows. Worry if the yellowing spreads rapidly to new growth.

Stopping it coming back

Maintain a consistent watering schedule and ensure the tree gets maximum sun exposure.
