Cigar plants, also known as Cuphea ignea, are popular among gardeners due to their vibrant red and orange flowers that bloom all year round. However, like any other plant, cigar plants are susceptible to diseases that can cause damage and even death if left untreated. In this article, we will discuss some of the most common cigar plant diseases, how to identify them, and how to treat them.
Identification of Common Cigar Plant Diseases
