Why is treatment generally not recommended for galls on ornamental plants?

Galls on ornamental plants are typically not treated because, while they may detract from the aesthetic appeal of the plants, they do not usually pose a significant threat to the overall health of the plants. Many galls result from the activity of insects or mites, which induce abnormal growths in specific parts of the plant. These growths can be unsightly, but they rarely lead to serious harm such as stunting growth or affecting the plant's ability to photosynthesize.

In many cases, plants can tolerate the presence of galls, and the ecological balance remains uneffectively maintained without intervention. The focus often shifts toward managing the overall health of the plants and ensuring proper care, rather than treating individual galls. Therefore, the decision to refrain from treatment stems from an understanding of the relatively benign nature of galls in most ornamental situations.
