What is the reason for the black leaves of gardenia?
The black leaves of gardenia are usually caused by three reasons. First, the temperature is too low; gardenias prefer a warm environment and are not cold-resistant. If they are exposed to low temperatures for a long time, they may be frostbitten, causing the leaves to turn black. Second, too much sunlight; although gardenias like light, they only require diffused light. If they are exposed to strong sunlight for a long time, they may be scorched, leading to black leaves, and even causing the leaves to fall off in large numbers. Third, they may be infected with diseases or pests. Regardless of the cause, it is necessary to treat and address the issue promptly to prevent further deterioration.
