Edema on monstera deliciosa

monstera deliciosa with edema

What's Happening

Edema occurs when a Monstera takes up water faster than it can transpire it. This is usually caused by overwatering during periods of high humidity or cool temperatures. It manifests as small, water-soaked bumps or muddled brown spots that are not mushy, often confused with bacterial leaf spot.

How to Fix It

  1. 1

    Improve airflow around the plant with a fan.

  2. 2

    Reduce watering frequency, especially on cloudy or humid days.

  3. 3

    Consistency is key: avoid letting the plant go bone-dry and then saturating it.

What You'll Need

humidifier hygrometer potting mix perlite

How to Prevent It

Maintain consistent 50-60% humidity and provide bright light to keep transpiration rates steady. Use unglazed terracotta pots to help wick excess moisture.
