Can Pot Plants Tolerate 125 Degrees in Greenhouse?

Greenhouses provide an exceptional environment for pot plants to thrive in. However, one of the major concerns that gardeners and horticulturists face is the maximum temperature that pot plants can tolerate in a greenhouse setting. The optimum temperature range for most pot plants is between 65 to 75 degrees Fahrenheit; thus, a temperature of 125 degrees will most likely have negative effects on pot plants.

How High Temperatures Affect Pot Plants?

High temperatures cause stress to pot plants, resulting in wilting, drooping leaves, and in severe cases, death. Temperatures above 90 degrees can lead to heat stress which adversely affects the photosynthesis process, causing the plant to lose chlorophyll, resulting in leaf yellowing or shedding. When plants experience high temperatures above 100 degrees, they can start to desiccate or dehydrate, causing them to wilt and ultimately die.

What Can Be Done To Protect Pot Plants from High Temperatures?

One effective way to protect your pot plants from high greenhouse temperatures is to install shade cloth. The shade cloth reduces the intensity of sunlight reaching the plants. Additionally, adequate ventilation is crucial in regulating the temperature inside the greenhouse. Automatic ventilation systems can help to control temperature levels by opening and closing vents and windows when temperatures rise or fall, thereby maintaining an optimal temperature range.

Another approach to regulate the temperature is by misting or using a humidifier. Pot plants that require high humidity, such as ferns and orchids, benefit greatly from this technique. Lastly, it is essential to use a thermometer to monitor the temperature inside the greenhouse to prevent damage to the plants.

Avoid Overcrowding the Plants

Overcrowding the pot plants in the greenhouse can also contribute to high temperatures. Plants growing too close together can limit air circulation, making it difficult to regulate the temperature inside the greenhouse. One effective way to prevent overcrowding is by planting only the required number of plants to ensure adequate space for adequate growth and proper air circulation. Space the plants according to their size, and keep in mind the final size of the pot plant when choosing the spacing.

Conclusion

In summary, 125 degrees Fahrenheit is a high temperature that is detrimental to most pot plants grown in greenhouses. High temperatures cause heat stress, wilt, drooping leaves, and in severe cases, plant death. Protecting pot plants from high temperatures requires installing shade cloth, adequate ventilation, using thermometers to monitor temperature levels, and preventing overcrowding in the greenhouse. With these measures in place, your pot plants can thrive in a greenhouse environment.
