Cinnamon offers several advantages for garden plants:
Preventing Fungal Diseases
To promote healthy plants, use cinnamon to ward off cryptogamic diseases. Simply sprinkle a bit of cinnamon powder at the base of plants that are susceptible to mildew, rust, or powdery mildew.
Protecting Seedlings from Mold
Mold spores can threaten seedlings due to excess moisture. Use cinnamon’s fungicidal properties by mixing half a liter of water, two tablespoons of cinnamon, and an aspirin tablet in a bowl. Let it sit overnight, then soak the cuttings in this solution. The aspirin encourages root growth while cinnamon protects against mold.
