How one use mouthwash as rose fungicides?

Mouthwash can be used as a fungicide for roses due to its alcohol and antiseptic properties. To use it, dilute the mouthwash with water (typically a ratio of 1 part mouthwash to 3 parts water) and spray it onto the affected areas of the rose plant, ensuring thorough coverage on the leaves and stems. Apply this solution every few weeks or after rainfall to help prevent and control fungal infections. However, it's essential to test a small area first to ensure the plant does not react negatively.
