Screw pine · Pandanus tectorius

How do I fix root rot in my Pandanus tectorius?

It is less common for this plant to get root rot, and it usually happens due to heavy soil that holds too much water. Check the roots for a mushy texture and dark color.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Gently lift the plant to see if the roots are firm or mushy.
  3. Check if the pot has adequate drainage holes.

Likely causes

  1. Waterlogged soil

    Most likely

    How to tell: The plant looks wilted despite having moist soil, and the roots appear brown and slimy. You might notice a foul odor coming from the pot.

    What to do: Remove the plant from its pot and trim away any black, mushy roots with sterilized shears. Repot the plant into a fresh, well-draining potting mix.

  2. Poor drainage

    Possible

    How to tell: Water sits at the bottom of the pot for days after watering. The leaves may show yellowing or brown spots.

    What to do: Ensure your pot has large drainage holes at the bottom. Add perlite or coarse sand to your potting mix to improve aeration and drainage.

When to worry

Worry if the stem feels soft or mushy at the base, as this indicates the rot has spread to the main structure. If the roots are mostly black and mushy, the plant may not recover.

Stopping it coming back

Use a well-draining soil mix and never let the pot sit in standing water.
