3. Deadhead flowers. Remove spent flowers to direct the plant's energy towards leaf growth and recovery.

Monitoring Temperature and Humidity

Temperature and humidity play a significant role in plant health. Here's how to monitor and control them:

1. Use a thermometer. Place a thermometer near your plants to monitor temperature fluctuations. Most houseplants prefer temperatures between 65°F to 75°F (18°C to 24°C).

2. Monitor humidity. Use a hygrometer to monitor humidity levels. Most plants prefer a relative humidity of 40% to 60%. You can increase humidity around your plants by placing them on a tray filled with water and pebbles.

Common Mistakes to Avoid

When reviving heat-stressed plants, it's essential to avoid common mistakes that can exacerbate the problem. Here are some mistakes to avoid:

1. Overwatering. Avoid overwatering, which can lead to root rot and further stress the plant.

2. Underwatering. Conversely, avoid underwatering, which can cause the plant to become even more stressed.

3. Failing to monitor temperature and humidity. Neglecting to monitor temperature and humidity can lead to further stress and decline.

Preventing Future Heat Stress

Prevention is always better than cure. Here are some tips to prevent future heat stress in your plants:

1. Choose heat-tolerant plants. Select plants that are native to warm climates or have natural adaptations to heat stress.

2. Provide adequate air circulation. Ensure good air circulation around your plants to regulate temperature and humidity.

3. Monitor weather forecasts. Keep an eye on weather forecasts and take preventive measures before heatwaves or extreme temperature fluctuations.
