Banyan tree · Ficus benghalensis

Why is my Ficus benghalensis getting root rot?

Root rot is a serious issue for your Banyan tree that usually stems from sitting in soggy soil for too long. Check the moisture level deep in the pot immediately to see if the soil is staying wet for more than a week.

Check these first

  1. Stick your finger two inches deep into the soil to check for dampness.
  2. Smell the soil for any signs of decay or mold.
  3. Inspect the drainage holes to ensure they are not blocked.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and drop suddenly, and the soil smells musty or sour. You might also see the stems near the soil line turning soft or mushy.

    What to do: Stop watering immediately and let the top three inches of soil dry out completely. If the plant stays wet, gently remove it from the pot, trim away any black or slimy roots, and repot it into fresh, well draining soil.

  2. Poor Drainage

    Most likely

    How to tell: Water pools on the surface for a long time after you pour it in. The pot lacks holes at the bottom, trapping water around the roots.

    What to do: Move your tree into a pot that has large drainage holes at the bottom. Add perlite or pumice to your potting mix to help water move through the soil more quickly.

When to worry

If the trunk feels soft to the touch or the majority of the leaves have fallen off, the damage may be too extensive to save the tree. It is normal to lose a few older leaves as the plant adjusts to a new spot.

Stopping it coming back

Always wait until the top two inches of soil are dry before you add more water. Ensure your pot has plenty of drainage holes to let excess water escape.

Questions people ask

Can I save a tree with root rot?
Yes, if you catch it early enough. You must trim the dead roots and repot the tree into fresh, dry soil.
How often should I water my Banyan?
Water every 7 to 10 days, but only if the top two inches of soil feel dry. Always check the soil rather than sticking to a strict calendar.
