To effectively get rid of edema in succulents, it is important to create an environment that reduces relative humidity near the leaf surface. This can be achieved by implementing a few key strategies:
1. Increase plant spacing: By providing adequate space between succulents, you can improve air circulation around the plants. This helps to reduce the moisture buildup that can contribute to edema.
2. Improve air circulation: In addition to spacing, enhancing overall air circulation in the growing area is crucial. This can be achieved by placing fans strategically to promote the movement of air around the plants. Increasing ventilation in greenhouses or indoor spaces can also be beneficial.
3. Increase light intensity: Increasing the amount of light available to succulents can help to increase normal water loss through transpiration. This can be done by placing the plants in a location with more direct sunlight or by providing supplementary grow lights if needed.
4. Raise air temperatures: Succulents generally thrive in warm conditions, and increasing the air temperature can aid in reducing excess moisture. However, it is important to avoid extreme temperature fluctuations, as this can stress the plants. Gradual increases in temperature are ideal.
5. Adjust watering practices: During cool and humid weather, succulents are more prone to developing edema. To mitigate this, it is recommended to water less frequently during such conditions. Allow the soil to dry out between watering sessions to prevent waterlogged conditions that can contribute to edema.
6. Remove standing water: Ensure that any excess water, such as in saucers under pots, is promptly emptied. Standing water can increase humidity levels around the succulents and contribute to edema. Emptying saucers around 30 minutes after watering can help prevent this issue.
It is important to note that edema can also be caused by other factors such as overwatering or poor drainage. Therefore, it is crucial to assess the overall health of your succulents and address any underlying issues that may be contributing to edema.
In my personal experience as a gardener, I have found that implementing these strategies has been effective in preventing and reducing edema in succulents. By creating a well-ventilated and properly lit environment, while adjusting watering practices accordingly, I have been able to maintain healthy succulent plants with minimal edema issues.
