Cinnamon is as good for plants as it is for humans. "There are almost countless uses for cinnamon in the garden: it can be used as a nature-friendly pesticide, a repellent against annoying insects, or as a catalyst to promote root growth in plant cuttings," Plantura explains.

Scientific studies have found that cinnamon works against fungal pathogens. "Under laboratory conditions, scientists have shown that the elements in cinnamon powder inhibit the development of grey mould (Botrytis cinerea) and various species of Phytophthora." Spraying a mixture of ground cinnamon and water onto infected plants is an effective way to alleviate the symptoms of fungal infestations, too.
