Which flowers and trees among green plants and flowers are prone to sooty mold?

Sooty mold occurs because the sticky honeydew excreted by scale insects or aphids provides a nutrient base for pathogens in dark, damp environments; it is also known as soot disease.

Sooty mold mainly affects greenhouse flowers such as calla lily, evergreen, Aspidistra, Monstera deliciosa, jasmine, and woody potted flowers such as sago palm, camellia, goji, white magnolia, osmanthus, crabapple, Baisheng, oleander, etc. Pomegranate; it is also frequently infesting various potted citrus flowers and trees.

In the early stages of sooty mold, dark brown mold spots appear on the branches and leaves, later spreading into a soot-like mold layer, which obstructs the leaves' photosynthesis and normal respiration, making them unable to be displayed and observed.

The main way to prevent sooty mold is to strengthen greenhouse ventilation, keep air humidity low, avoid spraying water on the plants, and promptly remove insects and mites. Once the disease begins, immediately spray 0.3-0.5 degree Baumé lime sulfur mixture. Household flowering plants cannot be sprayed with lime sulfur mixture indoors. Only after diluting white wine with double its volume of water, wipe the soot off the leaves with cotton lint, then rinse with water and place in a ventilated spot to dry. Using a half-strength 100-times Bordeaux mixture to prevent sooty mold is also very effective.
