Will cayenne pepper harm plants

Cayenne pepper can harm plants if used in excessive amounts, as its active compound, capsaicin, can irritate plant tissues. However, in moderate quantities, it may act as a natural pest deterrent, helping to keep certain insects away without causing significant harm. It's important to test on a small area first to ensure that the specific plant species can tolerate it. Always dilute cayenne pepper with water when applying it to avoid potential damage.
