Combating Damping Off
Damping off is a fungal disease that can prevent seeds and seedlings from thriving. To combat this, sprinkle cinnamon on the soil right after sowing seeds. Repeat the process once seedlings appear to ensure their survival.

Cinnamon can also help disinfect and heal cuts on plants. After pruning, sprinkle a little cinnamon on the cut areas to prevent fungal diseases.
Keeping Pests Away
