Plants are Very Similar to People
As the temperature warms and the days lengthen, a plant’s thirst for water grows, and they sweat a little more like humans do. Only their roots get water from the soil, which then goes up the plant to the rest of the plant. As a result, in the summer, it is required to water plants twice with pure water.
Effects of Heat on Plants
Heat affects plants in several ways. One of the most apparent effects is dehydration. When the temperature rises, plants lose water faster through their leaves, leading to wilting, yellowing, and death if not addressed.

Another effect of heat on plants is sunburn. Just like human skin, the leaves of plants can burn if exposed to direct sunlight for too long. Sunburned leaves may turn white or yellow and eventually die, affecting the plant’s ability to photosynthesize and grow.
Heat can also increase the risk of pests and diseases. Hot and humid conditions create the perfect environment for pests like spider mites, aphids, and whiteflies to thrive. Additionally, high temperatures can cause plant tissues to soften, making them more vulnerable to fungal and bacterial infections.
