Oedema: Small Water Pockets Under Chilli Leaves
Oedema is a condition that occurs when small pockets of water form under the surface of chilli leaves. It’s usually caused by environmental or watering imbalances and can be a sign of stress in the plant.
What Causes Oedema?
Oedema is triggered when the roots absorb more water than the plant can transpire. This excess water creates pressure inside the plant, causing cells in the leaves to burst and form water-filled blisters or bumps. Key factors include:
Overwatering: Excessive or inconsistent watering can overwhelm the plant.
Poor Air Circulation: Humid, stagnant air prevents proper transpiration.
Sudden Environmental Changes: Shifts in temperature or humidity can stress the plant.
Low Light Levels: Without enough light, plants transpire less, leading to water retention.
How to Manage Oedema
Adjust Watering Habits:
Water only when the topsoil feels dry.
Ensure pots have proper drainage to avoid waterlogging.
Improve Airflow:
Place a fan nearby for gentle air circulation.
Avoid overcrowding plants to allow space for air movement.
Optimise Humidity Levels:
Use a hygrometer to monitor humidity.
Avoid overly humid conditions, especially in enclosed spaces.
Provide Consistent Lighting:
Ensure the plant gets enough sunlight or use grow lights if necessary.
Use Proper Potting Mix:
A mix that drains well and doesn’t retain excess water can help prevent oedema.
Prevention Tips
Gradually acclimatise plants to changes in light, temperature, and humidity.
Check the environment regularly to ensure optimal conditions for growth.
