Finger lime · Citrus australasica

Is my finger lime suffering from root rot?

Root rot is less common for finger limes unless the soil stays soggy for too long. Check the moisture level of your soil right now to see if it is waterlogged.

Check these first

  1. Stick your finger an inch into the soil to check for dampness.
  2. Lift the pot to see if water is sitting in the saucer.
  3. Smell the soil for a musty or rotten odor.

Likely causes

  1. Overwatering

    Possible

    How to tell: The leaves will turn yellow and drop off, and the soil will smell sour or swampy. The roots will look mushy and dark instead of firm and white.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the soil is heavy, repot the plant into a well draining citrus mix. Trim away any black or slimy roots with clean scissors.

  2. Poor Drainage

    Possible

    How to tell: Water pools on the surface for a long time after you water. The plant looks wilted even when the soil feels damp.

    What to do: Ensure your pot has large drainage holes at the bottom. Elevate the pot on bricks or feet to allow air to circulate underneath. Use a potting mix specifically designed for citrus to improve drainage.

When to worry

This is serious if the leaves are wilting and the stems feel soft. If the roots are mostly black and mushy, the plant may not recover.

Stopping it coming back

Only water when the top inch of soil is dry and always empty the saucer after watering.
