I know leaves on plants turn a certain color to indicate things. Can you help me classify some? For example, when a plant leaves turn black or when a plants leaves turn yellow what do these mean?

Black leaves can indicate disease or death; yellow leaves can indicate poor nutrition, sunburn, lack of water, or end of the growing season. Symptoms vary from plant to plant so it's important to research the growing needs of specific plants in order to determine the cause of leaf color change. Hope this answers your question!
