What happens when plants get too hot?
Typically, heat stress of a plant shows itself by wilting, a sign that water loss has taken place. Just as people and animals perspire, plants transpire, giving off water vapor through their leaves. When temperatures spike above 85 degrees Fahrenheit, plants can lose a lot of the water that they need to grow.
Can too much sun kill plants?
Too much sunlight for plants can sunburn them usually causing white areas on the liaves before the leaves die. Extreme wilting when they don't need water is another sign of too much light. It rots at the base of the plant as well as the plant wilting and drop it's leaves and dies.Is it bad to water plants in the heat?

Plants frequently wilt in hot weather, allowing both leaves and flowers to droop, sometimes to an alarming degree. Wilting occurs when the pace at which plant leaves dispel moisture into the air, in a process called transpiration, outpaces the ability of plant roots to supply enough water.Will plants recover from heat stress?
Summary: Heat-stressed plants not only need to produce new proteins to survive the stress, they need to make them right away, explain researchers.
