Question

Quizplus · Accepted Answer

Ethylene is a gas that is released during the burning of gas, and it has been shown to cause leaf drop and other symptoms of senescence in plants. The proximity of the grill to the camellia bush is likely causing exposure to higher levels of ethylene, which is causing the plant to lose its leaves.
