How to protect flowers from high summer temperatures

The hot summer is coming soon, and many flowers enter a dormant period during the high-temperature summer season. At this time, creating a suitable environment for flowers and keeping them away from high temperatures is very important, otherwise high temperatures may cause flowers to die within a short time.

Summer flowering plants

1. Shade from strong light

For flowers that fear both high temperatures and strong light, such as fuchsia, cyclamen, and orchids, during the high-temperature summer season, proper shading or keeping them under a shade frame can provide the necessary cool environment for their normal growth and development while avoiding heat in summer. If it is not possible to build a shade awning or there is no shade frame, you can also move them indoors during the day to shade and cool them, and move them outdoors at night to receive dew and ventilation.

2. Sprinkle water to cool down

Sprinkling water around the area where the potted flowers are placed and spraying water on the leaves can increase humidity and also help lower the temperature. It reduces leaf evaporation, enhances the flowers' drought resistance, and creates a cool and moist excellent micro-environment for the flowers. When sprinkling water, never water with cold water at the hot noon or on potted flowers that have already begun to wilt, otherwise it is easy to cause "chilling injury" and accelerate their wilting or death.

3. Avoid rain in time

Summer rain is frequent, heavy, and long-lasting. The sudden temperature drop caused by rainfall easily damages root hairs. After rain, water accumulates in the pots, which hinders root respiration and easily causes root rot; root rot is even more serious for fleshy-rooted flowers. All flowers that are weak or semi-dormant in midsummer should be placed in a rain-sheltered place, and even open-ground flowers should be properly covered; accumulated water after rain should be drained promptly.

4. Good ventilation

Both respiration and photosynthesis of flowers require sufficient fresh air, and ventilation can also reduce the concentration of harmful and toxic gases. Poor ventilation will hinder respiration, affect the normal growth of flowers, and even cause them to gradually die. Strengthening site ventilation, appropriately reducing the planting density of open-ground flower beds, and reasonable shaping and pruning can all achieve good ventilation results.
