How do I fix root rot in my cacao tree?

Root rot is a serious issue caused by soggy soil that prevents the roots from breathing. Check the roots immediately if the leaves are yellowing or dropping while the soil stays wet.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Check if the pot has functional drainage holes.
  3. Gently lift the plant to inspect the roots for dark, mushy sections.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil stays wet for more than a week and the plant smells musty or sour.

    What to do: Stop watering immediately and allow the top 2 inches of soil to dry out. If the soil is waterlogged, repot the tree into fresh, well draining potting mix.

  2. Poor Drainage

    Most likely

    How to tell: Water sits in the saucer after you water the plant.

    What to do: Ensure your pot has large drainage holes at the bottom. Empty the saucer within 15 minutes of watering so the roots do not sit in standing water.

When to worry

If the roots are black and mushy, the situation is critical and requires immediate repotting. It is normal for the tree to lose a few older leaves as it adjusts to a new pot.

Stopping it coming back

Always check the top inch of soil before watering and use a high quality, airy potting mix.
