#9 – Chinese Evergreen: The Coffee-Loving Color Champion

After my pothos success, I turned my attention to my collection of Chinese Evergreens. What happened next was nothing short of magical! These beautiful plants, especially my Silver Bay variety, responded to coffee grounds in ways that made me question everything I knew about Aglaonema care.
