Warning
Be cautious when using soaps and oils on your plants, as they can cause harm if applied under the wrong conditions. Applying them when plants are water-stressed or in direct sunlight can be particularly damaging.
Some plants are sensitive to these sprays, including Portulaca, hawthorn, and sweet pea. These plants may react negatively to the chemicals in the soaps and oils.
Temperatures above 90 degrees can also exacerbate the problem, making it even more crucial to use these products carefully. High humidity can also prevent rapid drying, leading to further issues.
Certain plants, such as cherries, plum, and horse chestnut, are more susceptible to damage from soap and oil sprays.
