What to Do When Begonia Leaves Turn Black
Begonia leaves turning black may be caused by overwatering, excessive sunlight, improper fertilization, or viral infections. It is necessary to water moderately, maintain a semi-shaded environment, provide shade during strong summer sunlight, and spray pesticides promptly to prevent viral infections. Blackened leaves should also be trimmed promptly to allow the plant to survive. If the main stem has already withered, it is difficult for the plant to survive.
What Causes Begonia Leaves to Turn Black
1. Overwatering: Begonias enjoy a moist environment but are afraid of waterlogging and dislike standing water. If overwatered, the roots can rot, causing the leaves to turn black.
2. Direct sunlight: Begonias prefer a semi-shaded environment. Excessive sunlight in the summer can burn the roots, leading to blackened leaves and leaf curling.
Reasons for Begonia Leaves Turning Black
1. Lack of fertilizer or fertilizer damage: Begonias require ample nutrients during growth. Insufficient or excessive fertilizer can cause the leaves to turn black.
2. Soil: Begonias prefer loose, well-draining, slightly acidic soil. If the soil is alkaline, it can cause the leaves to turn black and the flowers to become soft.
Remedial Methods for Blackened Begonia Leaves
Begonia leaves turning black may be due to viral infections such as begonia rust or rot diseases. It is necessary to spray pesticides promptly and trim the blackened leaves.
Begonia leaves that turn black can usually survive, but if the main stem has withered, new methods of propagation must be considered.
Should Blackened Begonia Leaves Be Cut Off?
Blackened begonia leaves should be cut off. If the blackening is just beginning and only affects the edges of the leaves, only the blackened part should be cut. However, if a large area of the leaf is affected, the entire leaf must be cut to prevent it from continuing to consume nutrients.
