The most common cause of the blackening of the leaves — dry air. The leaves deteriorate even those plants that caring owners regularly watered. But many inhabitants of the sills are very sensitive to dust and humidity. If these options do not meet their needs — plants sick. This is especially true for inhabitants of the tropics. For example, the dracaena owners face this problem regularly. Medication should be always at hand. This is the most common sprayer, which is necessary to use not less regularly than the lake.
Remove the damaged leaves. Spray the plant and in the future, try to do this more often. In large-flowers it is also advisable to regularly wipe the leaves. Do it best wet sponge.
Pay attention to how you water the plant. Many novice gardeners think that the more often watering is better for plants. But this is not always the case. If the plant is watered too often, the leaves begin to turn yellow and fall off. But overflow leads to blackening of leaves. This is especially true for colors that like good drainage and are sensitive to standing water in the soil. Oddly enough, the overflow is not like many plants in the humid tropics and subtropics. To start, try to remove blackened leaves and change the mode of irrigation. If this does not work, transplant the plant. Dig it out, remove the damaged roots. Sprinkle the wounds with charcoal. Pot for transplant it is better to take smaller size than the previous one. Wash it well with baking soda and pour over boiling water. Provide the plant good drainage. For this reason, often blacken the leaves of camellias, begonias and geraniums even unpretentious.

Especially do not like frequent fertilizing plants, accustomed to the meager nutrient-poor soils. Excess minerals can suffer including marsh and aquatic plants.
