Soursop · Annona muricata

How do I fix root rot on my soursop?

Root rot is a serious condition caused by fungi that thrive in wet, poorly aerated soil. You must act quickly to save the plant by inspecting the root system.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Gently pull the plant to see if it feels loose in the pot.
  3. Check the roots for a dark, slimy appearance.

Likely causes

  1. Poor Drainage

    Most likely

    How to tell: The plant wilts despite having wet soil and the leaves may turn yellow or drop.

    What to do: Carefully remove the tree from its pot and wash away the old soil. Trim off any mushy, dark, or foul smelling roots with sterilized scissors and repot in fresh, well draining soil.

  2. Excessive Watering

    Most likely

    How to tell: The soil stays wet for more than a week and the stem base feels soft or mushy.

    What to do: Allow the soil to dry out significantly between waterings. Use a moisture meter or your finger to ensure the top inch is dry before adding more water.

When to worry

If the stem base is soft or the roots are entirely black and mushy, the plant may be beyond saving. Act immediately at the first sign of wilting.

Stopping it coming back

Always use a pot with drainage holes and a high quality, airy potting mix. Never let the pot sit in a tray of water.
