Methods for Protecting Flowers from High Temperatures in Summer
Today's focus is on introducing you to the common knowledge of flower cultivation, specifically methods for protecting flowers from high temperatures in summer. Next, the site editor will introduce these methods to netizens.
In the past few days of high temperatures, many wild grasses on the roadside facing south have been sunburned to death, which was a profound realization. We know that wild grasses are more resilient than the flowers we cultivate, and if they can be sunburned to death, what about our cherished flowers that we take such good care of? Below, I will mainly discuss some commonly used methods for protecting flowers from high temperatures in summer.
We all know that when the external temperature approaches the upper limit for flower survival, the plants may grow poorly, develop slowly, or even die in a short period. High temperatures can strengthen the respiratory function of flowers while weakening photosynthesis, leading to an imbalance between nutrient accumulation and consumption. The plants fail to receive adequate nutrition, resulting in poor development or even halted growth. Ultra-high temperatures above 45°C can cause the proteins within flower cells to solidify due to heat, leading to plant death. High temperatures can cause the leaves of foliage plants to lose their green color and shorten the blooming period or cause the petals of flowering plants to scorch. Pests and diseases are also more active in high temperatures, posing a serious threat to flowers.
Shielding from Intense Light For flowers that are sensitive to both high temperatures and intense light, such as hanging begonias, cyclamen, and orchids, it is important to provide appropriate shade or place them under a shade shelter during the hot summer days to ensure their normal growth and protection from high temperatures. For those without a shade shelter or the ability to set one up, you can also move the plants indoors during the day to shade and cool them down, and then move them outside at night to receive dew and ventilation.
Watering to Cool Down Sprinkling water around the area where potted flowers are placed and spraying water on the leaves can increase humidity and lower the temperature. This reduces leaf evaporation, enhances the flowers' resistance to drought, and creates a cool and moist environment for the flowers. When watering, be sure not to do so in the scorching midday or pour cold water on wilted potted flowers, as this can easily cause "cold damage" and accelerate wilting or death.
Timely Rain Avoidance Many flower enthusiasts may think that rain is just the right thing to water their plants, but that's not the case. Summer rains are frequent, heavy, and last a long time. Sudden temperature drops caused by rainfall can damage root hairs. Accumulated water in pots after rain can hinder root respiration and cause root rot, which is even more severe in succulent-rooted flowers. Flowers that are weak or semi-dormant during the midsummer should be placed in a rain shelter, and even outdoor flowers should be covered appropriately; accumulated water after rain should be drained promptly.
Good Ventilation Flowers require plenty of fresh air for respiration and photosynthesis, and proper ventilation can also reduce the concentration of harmful and toxic gases. Poor ventilation can impede respiration and affect the normal growth of flowers, or even lead to gradual death. Enhancing site ventilation, reducing the planting density of outdoor flower beds, and pruning appropriately can all achieve good ventilation.
The above information on methods for protecting flowers from high temperatures in summer is provided for green plant enthusiasts to reference, and it is hoped that it can solve your problems in green plant and flower management.
