Why is my Watermelon Peperomia rotting at the base?

Root rot is the most common issue for Watermelon Peperomias, usually caused by soil that stays wet for too long. Check the soil moisture and the smell of the pot immediately.

Check these first

  1. Feel the top inch of soil for moisture.
  2. Smell the soil for a musty or rotten odor.
  3. Inspect the roots for a brown or slimy appearance.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The stems feel mushy at the base and the soil smells sour or swampy.

    What to do: Stop watering immediately and let the soil dry out completely. If the rot is advanced, remove the plant from the pot, trim away black or slimy roots, and repot into fresh, well draining soil.

  2. Poor Drainage

    Possible

    How to tell: Water sits in the bottom of the pot or the soil remains heavy and dense for weeks.

    What to do: Ensure your pot has drainage holes at the bottom. Mix perlite or orchid bark into your potting mix to increase airflow and drainage.

When to worry

If the stems are turning black and mushy at the soil line, the plant is in critical condition. It is normal for a few older leaves to die off, but mushy stems indicate a systemic issue.

Stopping it coming back

Always wait until the top inch of soil is dry before watering again. Use a pot with drainage holes to prevent water from pooling at the bottom.

Questions people ask

Can I save a plant with root rot?
Yes, if you catch it early. Trim the dead roots, repot in fresh soil, and be very careful with your watering schedule afterward.
How often should I water to avoid rot?
Water every 7 to 14 days, but only when the top inch of soil is dry. Never water on a strict calendar schedule if the soil is still damp.
